PRESIDENT'S MESSAGE

Dear Colleagues:

As incoming president, and on behalf of everyone in MAS, I would like to thank Tom Huber for the excellent job he did as the 1993 president. I know that Tom had some reservations when he accepted the job, especially when he found out that he had to deliver, as he put it, his first and last scientific talk at the 1993 MAS meeting.

The 1993 MAS meeting at Loyola Marymount University was a success. I would like to thank the Los Angeles local arrangements and program committees for the excellent scientific program and beautiful meeting locations. I would particularly like to thank Jack Worrall, the LAC chair, for all his efforts in keeping everything running smoothly. In addition to the meeting committees, I would also like to recognize the support of our sustaining members. Without their efforts, it would be difficult to hold successful meetings like the one in LA.

We were honored to have Chuck Fiori's widow, Virginia Fiori, with us during the week. On Monday, I presented Virginia with a plaque in recognition of Chuck's election to honorary membership in the Microbeam Analysis Society. Attending with Virginia were Chuck's daughter, Alice, and his maternal aunt, Agnes Tuberville. Honorary membership is the most prestigious award of our society and is reserved for recognition of those individuals who have made significant scientific contributions to the field of microbeam analysis. We have had only 15 members elected to honorary status and this was only the second time in the 27 year history of the society that we have awarded honorary membership posthumously. Chuck was elected to honorary membership in recognition of his fundamental and practical contributions to x-ray spectrometry particularly with the Si-Li solid state detectors, quantitative analysis with Si-Li detectors, analytical electron microscopy, biological microanalysis and quantitative x-ray mapping; and finally in recognition of Chuck as a great friend to everyone in MAS, always ready with a helpful hand and a good joke.

At the summer council meeting, we passed a motion presented by the Chuck Fiori Scholarship Committee to establish a Chuck Fiori Memorial Tour Speaker Program. A speaker, financed by the Chuck Fiori Memorial Fund, which totals in excess of 4,000 dollars, and the MAS tourspeaker budget,will be available to our local affiliate societies. The topics for the Fiori speaker will be practical in nature and will address the needs of technicians through lectures, workshops and other related activities. The first Fiori speaker, Cindy Zeissler, will be presenting a tutorial on sample preparation for microbeam analysis.

The council is also working to develop closer ties with microbeam analysis communities in the rest of the world. Dave Williams has worked closely with representatives from the European, Australian, and Asian societies to establish an international federation for microbeam analysis. The first international meeting is being planned for Australia in 1995.

The council also established a committee to propose ethical guidelines for financial support of invited speakers at our annual meetings. The committee is scheduled to make a report at the next winter council meeting.

I am pleased to announce that at the annual business meeting we approved the addition of two new local affiliates: the SouthEastern Electron Microscopy Society (SEEMS) and the Microscopy Society of the Ohio River Valley (MSORV). We also approved the slate of nominees for 1994 officers which includes Jon McCarthy as president-elect, David Simons as secretary, and Paul Hlava, Inga Musselman, Carol Swyt, and Nestor Zaluzec as directors.

As the journal, Microbeam Analysis, begins its 2nd year of publication, I would like to thank Rich Linton for his efforts as Editor-in-Chief. The journal is on schedule with respect to the number of submitted papers and the number of pages allocated for MicroNews. We, as MAS members, need to continue to submit our scientific papers for publication in Microbeam Analysis and to request our libraries to obtain journal subscriptions.

In looking forward to this next year as your president, I am pleased to see that the society has a very active and growing membership with the addition of two new local affiliates. It is my hope as president that we continue to expand our services to our members through programs like the Fiori Tour Speaker, the MAS distinguished scholars awards for students, and our interactions with other microbeam communities worldwide through the international federation.

John A. Small

President

MAS 1993

The 27th Annual Meeting and AEM Workshop

July 11-16 Loyola Marymount University

Report by Thomas G. Huber, Past President

The MAS council met Saturday, July 10, 1993. Of particular interest was council's decision to dedicate all donations to "The Chuck Fiori Memorial Fund", approximately $4,600, to advancing the education of technicians in our field. This year, an appropriate speaker will be placed on our tour to address matters of interest to our technicians. We are all quite sure that Chuck would have very much agreed with this decision. Council also confirmed Chuck's honorary membership and a plaque was handed to Ginny, Chuck's wife, and to his daughter Alice, both attending the meeting for the week.

Our nominating committee, chaired by then President-elect John Small, offered the following slate for consideration in our fall elections:

President - elect Jon McCarthy, NORAN

Secretary Dave Simons, NIST

Director (2 positions) Paul Hlava, Sandia

Inga Musselman, UT-Dallas

27th MEETING OF THE

MICROBEAM ANALYSIS SOCIETY

Loyola Marymount University

Marina del Rey / Los Angeles, California

July 11-16, 1993

I would like to take this opportunity to give you a quick update on some of the numbers for MAS 1993. We had a total of 317 registrations for the meeting. Of this number, 201 were full registrations, 10 were students, 37 were one day registrations, and 69 were exhibitors. We also had 19 guests and 20 children registered for the meeting. While this number was somewhat below our expectations, it is actually quite close to the number attending previous MAS only meetings. Given the current conditions weprobably did quite well. While the final financial numbers will not be available until all of the bills are cleared, the meeting is extremely close to breaking even. We owe a big thank you to the exhibitors who contributed to our success by having a booth, and a very special thanks to those who added to the success of our program by their contributions.

I hope all of you who came to Loyola this year enjoyed your visit and the excellent meeting we had. I assure all of you who have made comments to me on how well the meeting went, that I have forwarded those comments to the committee. The LAC was a wonderful group of people who worked very hard to put this meeting together. I would like to take this opportunity to thank them all for their hard work and commitment to MAS 1993 (Please see list). It is with mixed feelings that I leave this task behind. While it was a bit of a strain, it was also a very rewarding experience working with the LAC and seeing all of the planning come to such a fantastic ending. Did I really say I had a good time? Absolutely. Thanks again for coming.

Jack L. Worrall

LAC Chair MAS 1993

P.S. All non member attendees at this years meeting will become members automatically. The success of our meeting, and for that matter the society in general, depends on participation. I believe that we all know at least one person who would benefit by receiving the journal and attending our meetings. With a little extra effort I think I can get that one person I know to join MAS. How about you??

As has been said many times before, it is indeed a very special privilege to single out members of our Microbeam Analysis Society to receive Presidential Awards. This year the Presidential Award was presented to Dale Newbury, NIST, the Service Award was presented to Harvey Freeman, MAS Treasurer, and the Heinrich Young Scientist Award was presented to Phillip Russell, NCSU.

I am deeply indebted to all of the speakers taking part in the Presidential Symposium. Your presentations brought forth so many very positive comments for which I was able to take credit. Thank you one and all and a special thanks to all of you who filled the hall.

Last, but not least, all of us wish to thank the local arrangements committee, chaired by Jack Worrall, John Armstrong and John Porter, program co-chairs, and all of the committee members for a great meeting. The program was excellent and the socials were just great. The Mexican buffet and the Inca Peruvian folk music were outstanding. But Montazumas Revenge at Knotts Berry Farm truly took our breath away. It was a very nice afternoon. Thanks again LA Committee, you provided a real family environment both for young and old all week long. You were great. Thank you.

Finally, one last time, I must say thank you to our membership and to our council and committee chairs for giving me this wonderful opportunity to serve you and our society. Its been a very rewarding and memorable experience for me and I do hope a pleasant one for you.

Very Sincerely,

Thomas G. Huber

Past President, MAS

MAS 1993 - COMPUTER WORKSHOP AND SOFTWARE EXCHANGE

John Mansfield, MAS Computers Activities Chair

In conjunction with this year's MAS only meeting at Loyola Marymount University in Los Angeles, The Microbeam Analysis Software Library Computer Workshop and Software Exchange was held. The workshop was located this year in the registration area, a good location to welcome workshop attendees, as they were able to easily determine its location whilst waiting to register. The equipment available this year comprised three Apple Macintosh systems and two MS-DOS systems and an Apple LaserWriter. The free loan of the Apple computers was negotiated by John Mansfield and was courtesy of Rani Kelly the local Apple Higher Educational Representative. The MS-DOS equipment and the Apple LaserWriter were rented from a local rental company by Brad Lawrence. The LaserWriter proved invaluable in saving a number of attendees talks, since they were able to make last minute changes and additions to their view graphs. A number of new programs were added to the MASSL this year. Four Macintosh programs from the University of Michigan were added, three of which related to SEM diffraction pattern analysis and one was an image processing utility. ECPOrient performs crystal orientation determinations on electron channeling patterns. MisMat and FindCSL further process the outputs from ECPOrient to determine crystal texture and coincident site lattices. TiffMaker is a small utility to convert Tracor/Noran TN5500 images and X-ray maps and Kevex images and X-ray maps to TIFF images. Rich Waldo from GM

Research in Warren, Michigan updated his thin film X-ray analysis program. John Armstrong of Caltech updated his program CITZAF. Paul Carpenter, also from Caltech, has been busy converting CITZAF to run on the Macintosh and in the process has been porting it to C, thus enabling the program to be compiled on a wide variety of UNIX workstations in addition to PCs and Macs. A beta version of his code was added to the library and a full release version should be available soon (watch the readme files on the MASSL ftp server, freebie.engin.umich.edu, for details). The dispersed nature of this years conference, i.e. the fact that the sessions were located in lecture theaters all over campus, meant that there was a decrease in the attendance at the workshop compared to other years. However, it is estimated that there were over 50 of the conference registrants who took advantage of the workshop and in all the workshop was a success. Next years workshop will be held jointly with MSA and should feature a number of live demonstrations of microscopy and image analysis software and also a primer to computer communications. Further information will be made available in a later issue of MicroNews.

NEW MAS AFFILIATES

The MAS council, at its summer meeting, voted to approve the affiliation of the SouthEastern Electron Microscopy Society (SEEMS) and the Microscopy Society of the Ohio River Valley (MSORV). We welcome these two new affiliate members.

The SouthEastern Electron Microscopy Society was formed in 1965 in response to a need for support and diffusion of knowledge in the southeast about the new field of electron microscopy. Today we are a regional society representing over ten states with a membership of over 300. We are one of the largest and most supportive LAS's of the MSA and will be hosting the MSA 1998 meeting in Atlanta. Our 1994 meeting will be a joint meeting with Scanning 94 in Charleston, SC (May 16-20). Over the past few years our membership has evidenced a strong desire to expand our society to cover all fields of microscopy and analysis. To these ends we are very pleased to have become one of the newest LAS's of the MAS. We are looking forward to an equally long and prosperous association with MAS.

Sandra H. Silvers, President, SEEMS

The Microscopy Society of the Ohio River Valley was formed in 1981 to meet the needs of microscopists in the tri-state area of Ohio, Indiana, and Kentucky which share the watershed of the scenic Ohio River Valley. It is also affiliated with the Microscopy Society of America (MSA). The society, with about 150 regular members and 30 corporate members, is well balanced in its mixture of members in the physical and life sciences. At the 1993 spring meeting in Louisville which was held in conjunction with the Louisville Advanced Technology Council, the members voted to drop "Electron" from the society's name. At that meeting, it was also decided to petition MAS for affiliation because of the large number of members that are performing microanalysis. Many of its members are members of MAS and are excited about the new affiliation. MSORV is an active local society; it holds two meetings a year and a newsletter is put out on a regular basis. The society plans to take advantage of the MAS tour speaker program. MSORV is the host for the 1993 51st Annual Meeting of MSA in Cincinnati with Ruth V. W. Dimlich chairing the Local Arrangements Committee. The current MSORV officers are Robert R. Cardell, Jr. (who is the 1993 President of MSA), President; Scott D. Walck, President-Elect; Ann B. Kier, Secretary; and Ray Boissy, Treasurer

Scott D. Walck, President-Elect, MSORV

THE MAS TOUR SPEAKER PROGRAM FOR 1993-1994

As everyone should know, MAS sponsors a yearly visit by a nationally recognized expert in some facet of microbeam analysis to each of the affiliated societies. These Tour Speakers give a presentation on their special field of research at the affiliated society's home and at a mutually agreed time and date: MAS pays the expenses. During the Affiliated Societies Committee meeting of Tuesday, July 13, 1993 (at Loyola Marymount University in Los Angeles, during the MAS Conference) three people were selected as candidate Tour Speakers for MAS this year. These people, their affiliations, and their topics are:

Dave Bright, NIST

Image Processing and Free Software for the Microscopist

Jon McCarthy, NORAN

The Effect of Detector Dead Layer on Light

Element Detection

Cindy Zeissler, NIST

Preparation Methods for Particle Analysis: Picking Particle Preparation Procedures to Prevent Painful Problems

Enclosed are short abstracts and biographies for the three speakers. I would appreciate the various program chairs presenting this information to their societies and getting back to me as soon as they have decided upon a speaker and/or an approximate to definite date. I will try to arrange schedules so that the tour speaker program doesn't bankrupt the society. When enough of the societies have responded for me to schedule some tentative tour swings, I will chase after some of the laggard societies and twist some arms. I also want to add that we are always open to suggestions for future tour speaker authors and topics and even to alternate speakers in lieu of our list. If we think we can accommodate you, we will try.

If you have any questions, do not hesitate to contact me.

Abstract:

This tutorial will review some of the basic principles of image processing using example micrographs, and will illustrate the advantages and disadvantages of various algorithms and image processing operations. The talk can be slanted to the interests of the audience, and include examples from x-ray mapping, for example. Images and imaging problems from the audience can be discussed if I'm given them in advance. The talk can include an overview of image processing techniques, discussions of free software, review books, journals and network mailing lists.

Biographical sketch:

Dr. Bright has been a research chemist at the National Institute of Standards and Technology since 1976. In 1984, he joined the Microanalysis Group of the Center for Analytical Chemistry to develop an image analysis system, and apply image analysis techniques to various research problems of the group. Researchers use the system to automate electron microscopes, identify arrays in electron diffraction patterns, and examine x-ray maps. Dr. Bright has authored several dozen papers on image analysis since 1983, including an Interface article in Analytical Chemistry, and has given over twenty invited talks on the subject. He received his Ph.D. in Biophysics from Colorado State University in 1975, and is married with four children.

The Effect of Detector Dead Layer on Light Element Detection

Abstract:

Many factors influence the performance of EDS systems in the detection of photons below 1 keV. The major factors are the electronic noise of the system, the properties of the semiconductor material used as the detecting element, photon absorption by the vacuum window of the system, the metals used as voltage contact, and the "dead layer" associated with the front surface of the detector diode.

In the last five years, much progress has been reported in reducing the effect of several of these factors. Reduction of electronic noise of EDS system, and the use of new vacuum window materials are well known. The use of alternative semiconductor materials for detectors, specifically high purity germanium, in place of lithium drifted silicon has also met with some success. However, the subject of the dead layer has not been explored in much detail in the recent literature. After a brief review of the state of the art in electronic noise reduction and window technologies, this paper will discuss the spectral characteristics caused by the detector dead layer and the efforts made to minimize these effects. The results of these studies has lead to a better understanding of the detector dead layer and to significant improvements in light element sensitivity of EDS systems.

Preparation Methods for Particle Analysis (Picking Particle Preparation Procedures to Prevent Painful Problems)

Cindy Zeissler (Fiori Memorial Speaker)

Surface and Microanalysis Science Division

National Institute of Standards and Technology

Gaithersburg, MD 20899

(301) 975-3910

Abstract:

Particle preparation for electron or ion beam analysis can require special methods and tricks. One may need to worry about how to distribute a heterogeneous powder evenly on a substrate without biasing the results, or one may wish to mount a single precious particle without losing or altering it. Methods such as static control, ultrasonification, suspension dispersion and evaporation, filtration, film casting tricks, and micromanipulation can be utilized to achieve these goals. Trace analysis or single particle work may require the use of light microscopy and clean room practices. The choice of liquid reagent used for dispersion or various handling and preparation methods can also be an important factor to consider to avoid chemical and morphologic artifacts. This talk will discuss a broad range of practical topics pertinent to both bulk and single particle preparation: equipment, reagents, methods, artifacts, and results. Micrographs will be used to help elucidate the special behavior and problems of particles in the microworld and how to handle them. Tricks and tips will be offered for problems such as avoiding "tiddleywinks" or static-induced losses, how to turn a single or an entire field of particles upside down to analyze the other side, "quickie" preparation methods, clean methods for trace analysis, and others.

Biographical sketch:

Cynthia Zeissler began work at NIST in 1985. She holds a B.S. in Geology from the University of Maryland, College Park. Her specialties include neutron-induced radiography and autoradiography using track-etch and semiconductor detectors, light and electron microscopy as applied to particle analysis for materials science problems, and clean room operations for trace analysis. Recent areas of research include ppm-level microscale mapping of uranium in minerals, and the co-development of a novel video radiation imager. The sample preparation skills developed to support these and other analytical methods have emphasized particulate samples, with special attention to clean, nondestructive micromanipulation and preparation methods of single microscopic particles.
