Abstract
The elongated monolithic radiation absorbing body of a gamma ray sensor has its entire external surface exposed to coolant for establishing a uniform heat sink temperature throughout. Cold junction regions are formed in portions of the elongated body of reduced cross-sectional area sufficient to produce measurable signal levels from a differential temperature thermocouple. A removable low melting filler in the reduced cross-sectional portions of the body enable accurate electrical calibration of the sensor.
