Research aimed at the development of new techniques includes the study of promising technological advances, such as; superconducting magnet technology, new electronic techniques for on-line data collection, improved automatic analysis systems, and new, concepts for detection of the higher energy particles to be available in the near future. Experience indicates that technological developments such as these frequently have an impact in many areas other than high energy physics. Also supported are advanced accelerator research and development studies, which are expected to lead to improved and more economical new accelerators, or make possible significant improvements in the capability and efficiency of existing accelerators. The major requirement for additional funding in FY 1971 is related to the National Accelerator Laboratory. An increased level of effort is required to provide pre-construction R&D support, so that design decisions can be made on a time scale properly phased with the construction schedule for the 200 Bev accelerator. An increase in the level of pre-operational R&D is also necessary in order to prepare for experimental utilization of this facility. Increases to partially compensate for increased costs are included for high priority activities supported at the Alternating Gradient Synchrotron and the Stanford Linear Accelerator Center. To permit these increases, it is necessary that the funding of other activities within the program be reduced below the FY 1970 It is contemplated that this will include complete shut-down of the Princeton-Pennsylvania Accelerator in FY 1971, a level. substantial reduction in the level of operation of the Cambridge Electron Accelerator (which will permit only the colliding beam research to continue), shutdown of the heavy liquid bubble chamber at Argonne, shutdown of the Lawrence Radiation Laboratory 25" bubble chamber, and a reduction in the operating level of the Bevatron, and substantial cutbacks throughout the university program. There follows a breakdown of the estimates for each major accelerator: The $2,000,000 funding level programmed for this facility will require shutdown of PPA by the end of FY 1971. This schedule The $2,400,000 funding level programmed for this facility will require a substantial reduction in research activities of the CEA during FY 1971. Termination of the research program devoted to the more conventional electromagnetic type experiments near the beginning of FY 1971 will permit scientists to concentrate on obtaining results from the colliding beam experimental program; since CEA is the only U.S. facility with any capability to carry out these important experiments. During the latter half of FY 1970, repetition rate and average intensity of the AGS will be increased to twice their previous value. This increase in intensity, coupled with the recently developed capability of delivering particles to the slow extracted proton beam simultaneously with particles to internal secondary beam targets will considerably enhance the experimental capability of the AGS facility. Several high performance secondary beam branches from the slow extracted proton beam will be available to experimenters for the first time early in FY 1971. These branches will permit increased utilization of the highest energies of the AGS; and in addition will permit experimentation with beams of particle types not previously available. An increase of $700,000 is programmed for the AGS to assist in utilization of these new capabilities and maintenance of other high priority research activities. This is expected to require curtailment or postponement of other ongoing activities. c. Operations ..... Total...

A reduction of $320,000 is months of FY 1970 and the first two months of FY 1971 for installation of the new vacuum chamber. planned for this activity but the accelerator itself is expected to continue near the FY 1970 shift level when in operation, although the machine operation may be curtailed for several additional weeks pending detailed evaluation of the FY 1971 program. It is anticipated that this will require shutdown of the 40" heavy liquid bubble chamber, which is the only one in the U.S. Operation of the new 12' bubble chamber and operation of the new beams and targetry will be accomplished by a reduction in other activities.
