Supercollider 3

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.
