A pulsed, compact, low-background X-ray generator

Abstract

A novel type of pulsed X-ray generator especially suitable for rare event searches, as dark matter and neutrino experiments, has been developed. Being compact and built with selected radio-pure materials, it is appropriate for low-background experiments. UV light generated by a pulsed lamp produces photoelectrons on a metallic cathode, which are subsequently accelerated to produce X-rays. The X-rays are emitted in bunches with a time resolution better than 1 ns and the system provides a fast trigger for event tagging. We present the idea of the new X-ray generator as well as experimental results showing the proof of concept of the device. Data are in good agreement with simulation results and future optimisations of the system are also discussed.
