Abstract

The CLEO III detector has recently commenced data taking at the Cornell electron Storage Ring (CESR). One important component of this detector is a 4 layer double-sided silicon tracker with 93% solid angle coverage. This detector ranges in size and number of readout channels between the LEP and LHC silicon detectors. In order to reach the detector performance goals of signal-to-noise ratios greater than 15:1 low noise front-end electronics together with highly regulated low noise power supplies were used. In this paper we describe the low-noise power supply system and associated monitoring and safety features used by the CLEO III silicon tracker.
