Abstract
Large (6,3 × 6. 3cm2) linear Silicon Drift Detectors were developed for use in the SVT, the inner tracking detector of the STAR experiment at the RHIC Collidcr. The concern of this paper is to estimate the effects of neutron and proton radiation damage to these devices and associated electronics. Detectors and their associated electronics were irradiated with 10n - 1012/cm2, 1 MeV equivalent neutrons and 101° - 1012/on2, 24 GeV protons. I-V and C-V characteristics of diode test structures were used to determine depletion voltages, lifetimes, and reverse bias values. Measurements of the voltage and drift linearity with laser injection show the effects of irradiation on the detector performance. Measurements of noise levels show the effects of irradiation on the front-end electronics.
