Summary

Description and test results of a new stationary thermometry system used to map the temperature of the outer surface of 1.5 gigahertz superconducting single-cell cavities during operation at 1.6 K. The system comprises 764 removable carbon thermometers whose signals are multiplexed and scanned by a computer. A complete temperature map can be obtained in as little as 0.1 second at a temperature resolution of about 0.2 milliK. Alternatively, it has been demonstrated that if the acquisition time is increased to several seconds, then a temperature resolution on the order of 30 microK is possible.
