IMAGE FURNACE FOR LOW YIELD NUCLEAR WEAPONS EFFECTS SIMULATION.

Abstract

The capability of the Naval Applied Science Laboratory for direct simulation of thermal effects due to nuclear weapons has been extended to low yield devices (as small as 10 kt) by the installation of a high performance servo-driven shutter in a carbon arc imaging furnace. The system can simulate thermal pulses from weapons with yields of from 10 kt to those from the largest known devices. It can deliver a peak irradiance of 45 cal/sq cm/sec over an effective spot diameter (irradiance at least 90% of macimum) of approximately 17 mm using a single ellipsoidal mirror. With the addition of a second mirror, a peak irradiance of over 200 cal/sq cm/sec can be obtained with an effective spot diameter of about 4mm. Arbitrary pulse shapes such as square waves and sinusoids can also be delivered. Provision is made to record irradiance histories and source characterystics during each exposuru without 0p6resy0b2y y4bu8fe8ing with samp2e yr80dy0byo4. (Author)
