Compact microwave source for excitation of electrodeless lamp (exciting electrodeless lamps)

摘要

(14) for the antenna terminal (12) of the magnetron (11) for generating electromagnetic energy in the microwave region. The elongated body 14 extends the length of the antenna 12 to control the phase loaded on the magnetron 11. The cylindrical grounding flange 16 and the apertured film 19 surround the electrodeless lamp 15 and consequently the energy is held in the space surrounded by the perforated film 19 and the cylindrical grounding flange 16, And emits microwave energy to excite the gas in the chamber 15. The stretch material 14 for the antenna 12 has a length that maintains the phase reflection coefficient at a level that does not adversely affect the magnetron operating frequency.
