Abstract :
A microprocessor-based cryogenic refrigerator controller developed at the Los Alamos Scientific Laboratory provides automatic cooldown and subsequent monitoring of liquid hydrogen targets. The controller performs the initial cooldown of the cryogenic system and provides continuous monitoring of the important system parameters. An alarm is sounded to summon an operator in the event of any parameter exceeding predetermined limits.
