Proposal for time separated antiproton beam at BNL

During the past year the authors collaborated in preparing a proposal to develop a time purified/separated antiproton beamline (TSB) at the Alternating Gradient Synchrotron (AGS) of the Brookhaven National Laboratory. The proposed beamline is 1 kilometer long and would operate over a momentum range of 1-10 GeV/c. The principle feature of the beamline is its length, which would permit purification of the anti p beam by allowing time for π decay. In addition, by timing off of the AGS rf, clear temporal separation can be achieved through time-of-flight versus particle mass measurements. Total beam flux is estimated to be 107 particles per second with as many as 106 antiprotons per second
