IRCM Lamp Development
Abstract
The purpose of this program was to design, develop and fabricate two prototype CASPAR/CAIR arc lamps. The EIMAC IRCM source was patterned after the ADM-1 series E source. The lamp is of double envelope design. The inner (arc) envelope consists of a synthetic(cesium-filled)sapphire tube with refractory metal electrodes. The outer envelope, quartz/metal assembly, is evacuated to protect the inner envelope from oxidation during operation. High temperature brazing alloys for sapphire/Cb-1Zr seals were evaluated and thermal cycling tests made on brazed seal structures. Techniques for cesium filling were investigated. Power tests were run with the sapphire inner envelope portion in a vacuum bell jar to verify the thermal design and determine basic design deficiencies.
