Abstract
Integrated photodiodes and silicon JFET preamps are used for the optic al readout of the Gravity Probe B cryogenic star tracking telescope. T he heated circuit assembly is mounted on a thermal isolator so that it can be heated to around 80 K while the telescope remains at its opera ting temperature of 2.8 K. We present test results of the readout with a night quality telescope.
