Abstract

Emission properties of Scandia Doped Impregnated (SDI) cathodes tested at DC model has been investigated in close-spaced diodes with water-cooled copper anodes. Space Charge Limited (SCL) current density of over 40 A/cm2 has been measured at 950°Cb after temperature compensation for electron cooling. The life test has lasted for more than 500 hours and is going on.

掺钪浸渍分点阴极的直流发射特性

在直流模型下，研究了含铜水冷阳极的钪掺杂浸渍(SDI)阴极的发射特性。在950°Cb温度补偿电子冷却后，测量到空间电荷有限(SCL)电流密度超过40 A/cm2。寿命试验已经持续了500多个小时，并且还在进行中。
