Abstract
An arc lamp comprises nine component parts that are brought together in three brazes and one TIG-weld to result in a finished product. An anode assembly is brazed with the rest of a body sub-assembly in one step instead of two. A single-bar cathode-support strut is brazed together as one step. A window flange and a sapphire output window are brazed together with the product of the strut braze step in a mounted-cathode-braze step. A copper-tube fill tubulation, a kovar sleeve, a ceramic reflector body, an anode flange, and a tungsten anode are all brazed together in a “body-braze” step. The products of the mounted-cathode-braze step and body-braze step are tungsten-inert-gas (TIG) welded together in a final welding step. A lamp is finished by filling it with xenon gas and pinching off the tubulation.
