Question: Why is $60.5 million needed for the Stanford Linear Collider in FY 1985? How would a $20 million reduction affect the project? Answer: The Stanford Linear Collider (SLC) was planned on an optimized three-year construction schedule. The $60.5 million requested for SLC is required to maintain the schedule for this important project. The SLC project has gotten off to an excellent start in FY 1984. The $32 million construction funds appropriated by Congress for FY 1984 was made available to the Stanford Linear Accelerator Center (SLAC) on October 3, 1984; within a week, the first major contract was awarded by SLAC. This contract was with Gates and Hodges, a California-based tunneling contractor, for construction of the two arc tunnels that will contain the magnets which guide the electrons and positrons from the end of the existing SLAC linac to the SLC interaction region. Since then, additional large contracts have been let for procurement of magnet steel and for production of magnet laminations. Several major milestones have been completed; among them improvement of the SLAC linac and success of efforts to reduce the electron and positron beam cross sections and acceleration of tightly bunched, high peak current electron beams through the first third of the two-mile long linear accelerator with proper characteristics for SLC operation. ability to continue the excellent progress on SLC and meet the planned goal of first beam in October 1986 is paced by funding. The FY 1985 funding request is essential to complete procurement of critical technical components and to place under contract the construction of the interaction hall which is on the critical path for completion of this project and where experiments will be located. The A $20 million reduction in the fiscal year request of $60.5 million for SLC construction would delay the project by a full year and would add about $9 million to the cost, depending in part on the final funding profile provided. A primary factor in the increased cost is that the staff supporting the SLC activity would have to be maintained for an additional year both in the R&D and construction phases of the SLC project. The present estimate is that the additional costs to the project would be $6.0 million for incremental staff costs and inefficiency associated with a one-year delay and that the escalation on deferred funding would add an additional $3.0 million to the total estimated cost. The SLC has been developed with a dual purpose; to take a major step forward in accelerator technology which is essential to future progress in the capability of electron-positron colliders and to provide a copious source of the newly discovered Zo particle for the purpose of studying the electroweak interaction. The SLC will give U.S. physicists a first and unique opportunity in the world to carry out precision research in this scientifically exciting and important area of physics. Question: Provide a list of the proposed GPP projects at each laboratory including the TEC of each. Also, please provide a breakdown for FY 83 and FY 84. Answer: The requested information for GPP projects is shown in a table I would like to insert in the record. |
