Abstract
THERMACORE HAS RECENTLY DEMONSTRATED HEAT FLUXES IN EXCESS OF 6000 W/cm2 AND HEAT TRANSFER COEFFICIENTS OF NEARLY 100 W/cm2 - DEGREE C USING AN APPROACH CALLED POROUS METAL HEAT TRANSFER,USING COPPER AS THE HEAT EXCHANGER MATERIAL, AND WATER AS THE COOLANT. THE PROPOSED PROGRAM WILL MEET ALL SEMICONDUCTOR LASER ARRAY COOLER (SLAC) REQUIREMENTS BY ADAPTING POROUS METAL HEAT TRANSFER USING APPROPRIATE MATERIALS, COOLANT, AND PACKAGING. THIS WILL ELIMINATEN COOLING ISSUES AS LIMITING FACTOR IN LASER DIODE OPERATION. PHASE I WORK WILL INCLUDE DEFINITION OF ALL RELEVANT REQUIREMENTS FOR SLAC DEVICES. THE PROPOSED PROGRAM WILL UTILIZE POROUS METAL HEAT TRANSFER TO ACHIEVE COOLING RATES OF OVER 1000 W/cm2 AND ELIMINATE COOLING ISSUES AS LIMITING FACTOR IN SLAC POWER OUTPUT. PHASE I WILL DEMONSTRATE A HEAT EXCHANGER THAT MEETS SLAC COOLING REQUIREMENTS.
