Machine Advisory Committee Reviews the GDE
The Machine Advisory Committee (MAC) reviewed the GDE for the second time last week at KEK in Japan from 20 to 22 September. The MAC, appointed by the International Linear Collider Steering Committee, is made up of an experienced international group of accelerator experts. The first review was held at Fermilab last spring and served to introduce the committee to the GDE. This time, the review looked more deeply into specific areas of our efforts. Today, I highlight some of the key observations and recommendations of the committee, based on what we were told during the closeout session for this review. The complete report should be issued within a few weeks.
The MAC also discussed design issues and endorsed the change of the baseline to 14mrad x 14mrad crossing angles, which I reported on in last week's column. They also expressed satisfaction with the efforts we have made to communicate design issues with the high-energy physics community, the initiation of a task force to demonstrate our baseline gradient of 31.5 MV/m, the studies and design considerations we are taking regarding availability and the progress we are making in coordinating the global R&D program.
The next meeting of the MAC will be at the Cockcroft Institute at Daresbury in the U.K. in January 2007. That review will be at a critical time for us as we should be very close to releasing our draft RDR with preliminary costing. That MAC review will provide an important check on our readiness.
