Abstract
In order to conserve battery power of an electrically-operated cryogenic ler for an infrared imaging detector, a control logic is inserted between the battery and the cooler. This logic operates to maintain the detector at a higher than optimum operating temperature in a "STANDBY" mode, but holds the detector at optimum temperature in an "ON" mode.
