DESIGN OF 1.2 GEV SCL AS NEW INJECTOR FOR THE BNL AGS

Gradient Synchrotron (AGS) accelerator complex at the Brookhaven National Laboratory (BNL) to provide an average beam power of 1 MW at the energy of 28 GeV. The facility is to be used primarily as a proton driver for the production of intense neutrino beams [1,2]. A study of a proton Super-Conducting Linac (SCL) as the new injector to the AGS has just been completed [3] and found feasible. We are now initiating a second design phase with more emphasis on engineering considerations, namely: cryogenics, cryostat design, RF cavity design, RF power couplers and power sources, conventional engineering, and insertions for transverse focusing and other beam utilities. Some of these issues are addressed in this paper
