Abstract
Temperature sensitive photodetectors are temperature stabilized by coupling the photocathode of a photodetector in heat exchange relationship to a heated casting which acts as a heat source for the photocathode. The photocathode is coupled to the casting by a metallic Z-shaped bracket positioned on an insulating block with one base of the Z being coupled to the photocathode and the other base being coupled to a metal box through a Mylar insulating spacer, the box being directly mounted on the casting. A printed circuit board associated with the photodetector is also mounted on the insulating block. The direct heat path from the heated casting through the Z-shaped bracket to the photocathode reduces the warm up time of the photodetector thereby more rapidly temperature stabilizing the photodetector.
