Abstract
Scintillation detectors used in space applications must meet rigid criteria for high performance at reduced pressure, at variable temperatures and must withstand extremes of shock and vibration. A large number of tubes have been subjected to shock and vibration tests. Ruggedized tubes withstood the tests and showed little change in gain. Measured temperature coefficients of gain varied from -.19% to -. 53% /°C, from 25°C to 70°C and may be circuit compensated. Battery and inverter type high voltage supplies have shortcomings which have been overcome in a high frequency voltage inverter circuit which supplies potential to each dynode directly. A preamplifier is described which has a voltage gain of one, a high input impedance and wide dynamic range such that further amplification is not required. The techniques described have been tested in several space flights.Keywords
