Preface

The fifth annual International Symposium on the Super Collider was a great success. Over 700 participants from around the country and the world gathered on May 6-8,1993, in San Francisco to mark the progress of the SSC, to discuss current issues, and to chart a course of action for the continued development of our understanding of basic subatomic matter.

Together, the American public, academic communities, private sectors and governments from around the world have embarked on a project critical to maintaining our nation's preeminence as the world's leader in basic scientific research and the practical application of scientific knowledge. America has long maintained a commitment to investing in our nation's future. The Super Collider represents an essential next step in the direction of scope of human knowledge. The theme of the conference reflects these important goals: "SSC­Focusing the World on Next Generation Science. "

The challenge for us today is to spread the message of the importance of investing in America's future. This is our task, and the task of supporters of the Super Colliderthroughout the nation. Without employing all of our energies, our nation will miss an historic opportunity to ensure America's scientific technological and economic leadership in the years ahead as we enter the next millennium.

Many exciting parallel and plenary sessions were planned in order to educate the participants on the great scientific activities and technological developments that are happening at the Super Collider. 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 community.

This year's plenary session speakers included:

Mr. Charles Anderson, Air Products and Chemicals, Inc. Mr. Joseph R. Cipriano, DOE Project Manager for the SSC Dr. Charles R. Perry, Chairman of the Texas National Research Laboratory

Commission Dr. Roy Schwitters, Director of SSCL Dr. Wolfgang K.H. Panofsky, Director Emeritus of Stanford Linear Accelerator

Center Dr. George F. Smoot, Lawrence Berkeley Laboratory Dr. Nicholas P. Samios, Director of Brookhaven National Laboratory Dr. John Toll, President of URA Mr. Robert W. Galvin, Chairman of the Executive Committee of Motorola, Inc.

The IISSC presented its annual award to Congressman Tom Bevill of Alabama, Chairman of the House Appropriations Subcommittee on Energy and Water. As a senior Member of the powerful House Appropriations Committee, our award recipient is responsible for legislation which funds all the Nations major energy research projects. Our award recipient has been a staunch supporter of the Super Collider since its inception. His support for the project has been instrumental in moving the project forward and his efforts deserve our recognition.

Another group which deserves special recognition is this year's program committee. It was chaired by Ms. Regina Borchard, from Martin Marietta. Her committee consisted of the following members for the IISSC Board of Directors:

Mr. Charles Anderson Dr. Paul Ayres Mr. Co by Chase Dr. William R. Frisken Mr. Henry Gandy Dr. Eric Gregory Dr. Hiromi Hirabayashi Dr. Thomas Kirk Mr. Ted Kozman Dr. Uriel Nauenberg Dr. Satoshi Ozaki Dr. Clyde Taylor Mr. Ken Wilson

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

For the fifth consecutive year, Pamela Patterson served as conference manager. Year after year, she manages a successful conference, despite the large size and scope of the IISSC. We appreciate and recognize her time and commitment to the SSC and to the conference.

The following companies, organizations, societies, and agencies assisted in producing IISSC 1993. Those listed below provided support in many ways, including financial, inkind, volunteers, or combinations of all three.

The 1993 International Industrial Symposium on the SuperCollider is a private non-profit corporation, whose Board of Directors serves as volunteers. The IISSC exists to promote the SSC program by sponsoring an annual symposium. Attendees can exchange ideas and learn about the possibilities created by the SSC program in furthering science, technology, and education. The 1993 Board was composed of the following members from industry, universities, government, and national laboratories.

To assure the success of the SSC in the coming years, the Board of Directors urges all the attendees to renew their commitment to this premier research program. This symposium is an excellent forum in which to learn the great news about the Super Collider.

Remember, it is our responsibility as industry, scientific and academic leaders to educate the American people, our elected officials and the world about the importance of the Super Collider.

On behalf of the nssc Board of Directors, we thank all those who attended and contributed to IISSC 1993.
