Preface
The third annual International Industrialization Symposium on the SuperCollider, IISSC-held March 13-15, 1991, in Atlanta, Ga.-was an enormous success. The number of attendees, exhibitors, and representatives from foreign countries surpassed the totals of previous years. There were 740 attendees, representing more than 2 dozen universities and colleges, 32 states, 9 national labs, 6 research centers, several government entities at the local, state, and federal level, 182 businesses & industry and 14 countries. More than 100 exhibits, sponsored by 85 organizations, added to the excitement.
"Getting Down to Business" was the theme of this year's Symposium. The fact that the Superconducting SuperCollider (SSC) is indeed underway was the message delivered by the Symposium's keynote speaker, Dr. Roy Schwitters, and expanded upon by the opening plenary speakers. The project is moving from the planning stage to actual construction, to development and procurement of equipment, and to resolution of the technical issues involved in advancing the state-of-the-art in areas such as theory, controls, systems, metallurgy, quality control, management, cryogenics, power systems, detectors, interagency cooperation and funding.
Plenary speakers included:
Paul Gilbert, Chairman of Parsons Brinckerhoff Quade & Douglas, Inc.
Dr. Thomas Kirk, Director of High Energy Physics at Argonne National Laboratory
Joseph Cipriano, DOE Project Manager for the SSC
Edward Siskin, General Manager of the SSCL
Robert Johnson, Program Director of Energy Programs, General Dynamics Space Systems
Bruce Boswell, General Manager of Collider Magnet Division, Westinghouse Electric Corporation
Kent Higgins, Project Director, Koch Processing Systems
Dr. Raphael Kasper, Chief of the Directorate for the SSCL
Edward Donley, Chairman of the Executive Committee of the Board of Directors for Air Products and Chemicals, Inc.
Dr. John Marburger, President of State University of New York at Stony Brook

John Clendenin, Chairman of the Board and Chief Executive Officer of BellSouth Corporation
Dr. Gary Gibbs, Acting Director, Office of the SSC, DOE
The symposium included a series of technical sessions offering discussions and technical papers on a variety of topics: accelerator systems, computers and controls, conventional construction, cryogenics, detectors, education, and various aspects of project management and systems engineering.
The program committee for this symposium included:
Dr. Thomas Kirk, Chairman
Dr. Edward Bingler
Dr. Thomas Bush
Dr. Paul Mantsch
Dr. Satoshi Ozaki
Dr. Giuseppe Scarfi
Dr. Clyde Taylor
Dr. William Wallenmeyer
Equally important was the contribution made by Pamela Patterson, who served as Conference Manager for the third year and tended to the numerous details necessary to coordinate such a large-scale, international conference.
Two special awards were presented at the meeting. The nssc award was presented to Dr. Alvin Trivelpiece by the IISSC Board of Directors for his substantial contribution to the SSC program in its formative stages. The U.S. Department of Energy's Distinguished Associate Award was presented to E. Parke Rohrer by the DOE in recognition of his outstanding contributions to the SSC magnet research and development program.
The 1991 International Industrial Symposium on the Super Collider is a private, nonprofit corporation, staffed totally by dedicated volunteers from business and industry; local, state, and federal government; university research; and national labs. The organization exists solely to conduct an annual symposium on the SSC in order to educate people about the project and thereby increase understanding and support.

Those listed provided support in many ways, including financial or volunteer staff assistance, or both. A total of $15,550 in direct funds contributions were raised this year for operating funds for the IISSC.
Continuing solid support is vital to the success of the SSC. Support is very much like a brick wall. Each brick is important to the whole and, in the wall, mortar gives all the individual bricks connection, continuity, and purpose. The SSC enjoys many good quality bricks of support. By learning more about the SSC, renewing our commitment, and working together, we refresh the mortar and provide the connectivity, the continuity, and quality of solid support necessary to assure that the SSC will become a reality.
