大直径钪酸盐阴极发射特性
Emission characteristic of scandate cathode with large diameter
摘要
Abstract
In order to acquire Kilo-Ampere level emission current,a 100 mm diameter scandate cathode was manufactured. A 2 MV injector test stand was established with a large area thermionic cathode. A 1 038 A emission current was produced with a diode voltage 1. 95 MV, pulse width 120 ns(FWHM), cathode temperature 1 120 ℃. The emission current density was 13 A/cm2. The results indicate that the ability of cathode emission relies on diode vacuum and cathode activation temperature.关键词
