Study in Spurious Sensitivity of Electronics in Space.
Abstract
The results of an experimental investigation into the interaction of protons, E = 318 MeV and 132 MeV, with selected multiplier phototubes and silicon photodiodes are presented. The devices were chosen because of their spaceborne applications and previous gamma ray, electron, and lower energy proton measurements. The energies are representative of those expected of particle beam weapons. A discussion of the operation of each device and its expected response to protons is presented. Testing at Los Alamos Meson Physics Facility demonstrated the temporal response of multiplier phototubes to be nanoseconds but requires microseconds for decay. Another test at the Harvard Cyclotron Lab. determined the transient response of these sensors to 132 MeV protons in the range of 100,000 to 2 X 10 to the 8th power P/sq cm sec. The response was very nearly linear, but was slightly less for most devices. The radiation sensitivity of each device was calculated as expected. The multiplier phototubes were the least sensitive.
