Description
Summary:Summary form only given. We report here experimental results from a miniature radiation source based on a ferroelectric cathode. One of the main characteristics of ferroelectric emission at low anode voltages is that the measured current exceeds the Child-Langmuir current by several orders of magnitude. On the other hand, cross field devices, like the magnetron, have inherently high conversion efficiency. It is therefore possible that a low energy cross field oscillator based on a ferroelectric cathode will allow us to investigate the important trade-offs between a space-charge dominated beam and high conversion efficiency. A ferroelectric cathode is used as the electron source in a low energy (
