Testing the GP-B telescope readout electronics on a flight quality telescope.
Abstract
Integrated photodiodes and silicon JFET preamps are used for the optical readout of the Gravity Probe B cryogenic star tracking telescope. The heated circuit assembly is mounted on a thermal isolator so that it can be heated to around 80K while the telescope remains at its operating temperature of 2.8K. The authors present test results of the readout with a flight quality telescope.
