LIQUID NITROGEN COOLING IN A CMOS COMPUTER SYSTEM.

Author(s) : CALLAGHER G. R., FARRELL J. A., COLONNA-ROMANO L. M.

Summary

IT IS WELL KNOWN THAT THE PERFORMANCE OF CMOS CIRCUITS IMPROVES AT REDUCED TEMPERATURES. A SMALL CMOS COMPUTER HAS BEEN DESIGNED AND CONSTRUCTED IN WHICH THE CENTRAL PROCESSING UNIT OPERATES IMMERSED IN LIQUID NITROGEN AT APPROXIMATELY TWICE THE CLOCK SPEED AS A SIMILAR ROOM-TEMPERATURE SYSTEM. THE SYSTEM USES A SINGLE-STAGE GIFFORD-MCMAHON REFRIGERATOR AND AN ELECTRONIC CONTROL SYSTEM TO MAINTAIN THE TEMPERATURE AND PRESSURE WITHIN NARROW LIMITS.
