Status of slow extraction of high intensity protons from Brookhaven's AGS

摘要

The Brookhaven AGS third integer resonant extraction system allows the AGS to provide high quality, high intensity 25.5 GeV/c proton beams simultaneously to four target stations and as many as 8 experiments. With the increasing intensities (over 7/spl times/10/sup 13/ protons/pulse) and associated longer spill periods (2.4 to 3 seconds long), we continue to run with low losses and high quality low modulation continuous current beams. We have an active program of high energy physics experiments, including the high precision measurement of the muons magnetic moment and the discovery of the rare Kaon decay, K/sup +/ /spl rarr/ /spl pi/ + /spl nu//spl nu/~. This program is continuing into the future with the rare symmetry violating process experiments currently being designed to operate at the AGS. In this paper we present results from operation of high intensity slow extraction, the problems we encounter, and our solutions to those problems.
