A Compact Setup Based on a Gas Diode for Studying of Cathodoluminescence

Resumo

A compact setup for investigating the cathodoluminescence was created on the basis of a gas diode, a compact GIN-55-01 pulse–periodic generator, and an industrial spectrometer. Under the excitation by a beam of runaway electrons with a pulse duration (full width at half maximum) of ~100 ps, the cathodoluminescence spectra of natural and synthetic diamonds, calcite, cesium iodide, zinc selenide, zirconium dioxide, sapphire, gallium oxide (III), cadmium sulfide, zinc sulfide, calcium fluoride, and other crystals were recorded. The prospects of using gas diodes, which were developed at the Institute of High Current Electronics (Siberian Branch, Russian Academy of Sciences), and pulsers, which were created by the FID-Tekhnologiya Company (St. Petersburg), were shown when studying the properties of pulsed cathodoluminescence.
