ABSTRACT:
A cold cathode gauge including a glow lamp or the like disposed within the vacuum space of the gauge for initiating the gauge discharge, the lamp emitting UV or blue light directly at least at the cathode of the gauge where the energy of the light is sufficient to release photoelectrons from the cathode to thus initiate the discharge. Various techniques for supplying power to the lamp are also disclosed.
