Paper Abstract

A ferroelectric based multiple radiation source is being developed and tested at JPL. This device has the potential to emit five radiation types enabling a new generation of compact, low power, low mass in-situ analysis instruments. These radiation types include visible light, ultraviolet, X-ray, as well as electron and ion beams. These types of emitted radiation can support multiple instruments that may potentially be used in future NASA missions to detect water, perform mineralogical/chemistry analysis and identify biological signatures. The source consists of a ferroelectric wafer having a continuous ground electrode on one side and a grid-shaped cathode on the other side. This source is placed in a vacuum tube and is used to generate plasma by switching high voltage pulses. A series of experiments were performed to evaluate the characteristics of the generated radiation and the results are described and discussed in this paper.
