Abstract
A light source is powered by a magnetron and has a quartz crucible having a plasma void with an excitable fill, from which light radiates in use. Two aluminum attachment blocks are attached together and the block is attached to a casing of the magnetron by screws—not shown. The quartz crucible is attached to the block by a Faraday cage, in the form of a perforate metal enclosure secured at its rim to the block. An output formation of the magnetron has a conductive, copper cap fitted in electrical contact with it. The cap is extended by a copper rod. The rod extends through the blocks into a bore in the crucible for coupling microwaves from the magnetron into the crucible. An airspace is provided around the cap in the block. From the cap, the rod extends with negligible air gap in an alumina ceramic tube through the airspace and a boss of the block located in an aperture in an end wall of the block.
