Abstract :
To characterize the electron cloud in RHIC, eleven custom electron detectors have been designed, fabricated and installed at a few RHIC warm-bore vacuum sectors for data collection during FY2003 runs. Prior to installation, the transmission and collection efficiencies of these detectors at various grid and collector bias voltages were measured using an electron gun with energy up to 1500 eV. This paper describes the design of the detector and the test system set-up, and summarizes the calibration results. In addition the calibration of a commercial microchannel plate is also reported.
