Abstract
A circuit is described which provides a simple power supply for ionising and running 125 W high-pressure mercury-argon arc discharge lamps (e.g. type MBL/U) on stabilised direct current. An improvement of 10-20 dB, at 300 mu m, in the total noise of an infrared interferometer is reported, relative to AC operation. The reasons for the improvement are examined.Keywords
