- -20- boiling reactor, which has a different H,0/U ratio, was operating at Arco on October 8, and that excursion experiments were being run with it. It is designed to run steadily at 300 psi and give 6 MW of heat. At 4:55 p.m, the visitors left, except for Dr. Zinn and Dr. T. H. Research matvers Johnson who remained for the session on Research Matters, of the Committee and the Secretary were present. All members The topic was high energy accelerators, Dr. T, H. Johnson reviewed the history of the Cambridge proposal Accel~ for a circular 6 Bev electron accelerator and the Princeton proposal Propos= for a 2 Bev proton accelerator of high intensity (100 x that of BNL's ats cosmotron). They would cost about $5 x 10® each, They had been budgeted for FY 56, and the budget proposals were currently being reviewed, They would probably be struck from the budget. An appeal “SSSGalabemade Tfthe GAC gave a favorable recommendation on the proposals. Dr. T. H. Johnson mentioned other current plans, some of them preliminary, in the high energy field: (1) the Midwest proposal; (2) the Stanford interest in a greater than 10 Bev linear accelerator; (3) latent interest at ORNL; (4) Berkeley plans to increase the 184" cyclotron energy to 750 Mev; (5) Columbia plans to increase their energy to 520 Mev; (6) the heavy ion accelerators at Berkeley and Yale, which are going ahead.
