title: An oscillator circuit to produce a radio-frequency discharge and application to metastable helium saturated absorption spectroscopy.
abstract: We present a rf gas discharge apparatus which provides an atomic frequency reference for laser manipulation of metastable helium. We discuss the biasing and operation of a Colpitts oscillator in which the discharge coil is part of the oscillator circuit. Radiofrequency radiation is reduced by placing the entire oscillator in a metal enclosure.
