Commissioning the polarized beam in the AGS
Abstract
The operation of a high energy polarized proton beam is described. A 2 micron of polarized H(-) was accelerated through the Linac to 200 MeV with a polarization of about 65%. One micron A was injected into the alternating gradient synchrotron (AGS) and acceleration attempts began. Several relatively short runs were made during the next 3 months. On June 26 the AGS polarized beam reached 13.8 GeV/c to exceed the previous ZGS peak momentum of 12.75 GeV/c. Commissioning continued to the point where 10 to the 10th power polarized protons were acclerated to 16.5 GeV/c with 40% polarization. Two experiments had a short polarized proton run. A description of the facility and of the methods used for preserving the polarization of the accelerating beam is presented.
