Preface

The fourth annual International Industrial Symposium on the Super Collider, rrssc held March 4-6, 1992, in New Orleans was a great success. Present at this year's conference were 839 attendees representing 24 universities and colleges, 34 states, 13 countries, 17 national laboratories, 11 research centers, many government entities at the local, state and federal levels, and 235 businesses and companies. This year's symposium also included 101 exhibits by 78 organizations. In all categories, this year's participation exceeded the totals of previous years and is an example of the growing support for the Superconducting Super Collider Program.

This year's program had many highlights. One of the best was a message from President George Bush, read by Linda Stuntz, Acting Deputy Secretary, Department of Energy. President Bush said that each of us "can be proud of the role that you are playing in building the Collider and in setting the stage for a new era of research and discovery in high energy physics."

The 1992 IISSC's theme was "SSC-Discovering the Future." This theme was chosen in commemoration of the SOOth anniversary of Columbus's voyage of discovery and the relationship of the SSC with discovery. This theme was articulated by all the speakers in the opening plenary session. Progress on the program was also very evident at this year's symposium. In the pictorial session, 66 photographs from all over the world were displayed to highlight progress in making the SSC a reality. In addition, we had the participation of over 100 local school children at the "Discovering for Education" luncheon, where Nobel laureate Sheldon Glashow showed how discovery and physics can also be fun. The Congressional speakers discussed this year's funding challenges and the inputs needed from all of us to make the program succeed. The quality and diversity of this year's sessions and speakers allowed the IISSC to meet its goals of promoting a fruitful exchange of ideas among the SSC's community.

This year's plenary session speakers included:

Andrew J. Jarabak, Westinghouse Electric Corporation Joseph Cipriano, DOE Project Manager for the sse Dr. Edward Bingler, Executive Director, Texas National Research Laboratory

Commission Dr. Roy F. Schwitters, Director of SSCL Edward Siskin, General Manager of SSCL George Robertson, Deputy Project Manager of SSCL Dr. Edward W. Kolb, Institute for Theoretical Physics, University of California

Dr. Fred Gilman, Associate Director, Physics Research Division, SSCL Dr. Volker Soergel, DESY Dr. Sheldon L. Glashow, Lyman Laboratory, Harvard University Linda Stuntz, Acting Deputy Secretary of Energy, DOE Dr. John Toll, President, Universities Research Association, Inc. Dr. Alvin W. Trivelpiece, Director, Oak Ridge National Laboratory Carleton H. Jones, Manager, Research and Development Space and

Telecommunications, Bechtel Corporation Dr. John B. Yasinsky, President, Power Systems, Westinghouse Electric Corp. Honorable Tom Bevill, Congressman from Alabama, Chairman of the House

Appropriations Subcommittee for Energy and Water Development Congressional Panel:

Honorable Joe Barton, Congressman from Texas Honorable Jim Chapman, Congressman from Texas Honorable Martin Frost, Congressman from Texas Honorable James Hayes, Congressman from Louisiana

The IISSC presented its annual award to Senator J. Bennett Johnston of Louisiana, Chairman Senate Appropriations Subcommittee for Energy and Water Development. The award was presented to Senator Johnston for his leadership in obtaining Congressional support for the funding increase obtained in FY 92. Senator Johnston has played a key part in the SSC's success and is well deserving of this year's award.

The Symposium included a series of parallel technical sessions offering papers on the following topics: education, superconductors, environment, safety, health, magnets, detectors, cryogenics, quality assurance, technology transfer, accelerators, and special sessions on SSC for the Layman and Small Disadvantaged Business Opportunities.

This year's program committee deserves special recognition. It was chaired by Dr. Thomas Bush, Associate Director, Magnet Division, SSCL. His committee consisted of the following members from the IISSC Board of Directors:

Mr. Charles E. Anderson Dr. William R. Frisken Dr. Eric Gregory Mr. T. Scott Kreilick Dr. Paul Mantsch Dr. Uriel Nauenberg Dr. Satoshi Ozaki Mr. Maurice M. Sabado Dr. Clyde Taylor Ms. Gully Walter

The program committee's effort was also supplemented by numerous other associates from government, industry, and national laboratories.

For the fourth consecutive year, Pamela Patterson served as conference manager. Through her attention to detail and expert management, the symposium's arrangements proceeded smoothly and without problems. For this she is to be congratulated considering the large size and scope of the IISSC.

Also, at that time the site and date of IISSC 1993 was chosen to be San Francisco, May 5-8, 1993, at the San Francisco Hilton.

viii

To assure the success of SSC in the coming years the Board of Directors urges all the attendees to renew their commitment to this premier research program. By attending the symposium, we can grow with the SSC, show support, and display to the world all that has been accomplished. Remember, however, the lessons learned in Columbus's voyage; that great discoveries occur from events that cannot be predicted. Let us all now set sail on the ship of SSC in "Discovering the Future."

On behalf of the IISSC's Board of Directors, we thank all those who attended and contributed to IISSC 1992. We cordially invite all to attend the 1993 symposium in San Francisco and I look forward to seeing you there. I am certain it will be another memorable event.

March 4, 1992

I am delighted to extend warm greetings to all those who are gathered in New Orleans for the Fourth Annual International Industrial Symposium on the superconducting Super Collider.

This impressive gathering of researchers, educators, public officials, and business and industry leaders underscores not only the progress that we are making with the Super Collider but also the scope and intensity of interest in this exciting project. Truly, it is an international undertaking -- one that will benefit people around the world as it yields greater insight into the fundamental nature of matter and energy. Each of you can be proud of the role that you are playing in building the Collider and in setting the stage for a new era of research and discovery in high energy physics.

The year ahead poses great opportunities and challenges as we work to uphold America's leadership in this important area of science and technology. It is critical that we maintain the momentum and the technical progress that we have achieved, and I commend you for your efforts to help ensure that we keep moving forward in the development of the SSC.

You have my best wishes for a productive conference.
