RHIC electron detector signal processing design

The RHIC gold beam intensity is presently limited by pressure rise at some warm sections, and the main cause is thought to be the electron cloud. For the FY2003 RHIC run, a system has been installed to characterize the electron cloud, if it exists. The system is comprised of electron detectors, high voltage bias supplies, signal amplifiers, and data acquisition electronics, all integrated into the control system. The 11 detectors are grouped into four locations, one in an interaction region and three in single beam straight sections. This paper describes the signal processing design of the detector system, and includes data collected from the FY2003 run.
