RF腔光阴极注入器中热发射度的测量研究

论文介绍RF腔光阴极注入器中热发射度的测量方法，在注入器中有三个因素影响热发射度的测量，它们是：射频场效应、空间电荷效应和发射度测量误差. 在注入器出口处，电子束发射度由：热发射度、射频场效应引起的发射度增长和空间电荷效应的发射度增长三部分组成. 论文从注入器中发射度增长理论和模拟出发，给出了一个能够消除射频场效应和空间电荷效应的热发射度测量方法.

Invetisgation of Thermal Emittance Measurement in RF Photoinjector

A new method for the measurement of the thermal emittance in the RF photoinjector is introduced in the paper. The measurement are affected mainly by three factors which are the RF effect, the space charge effect and the error of measurement. According to the theory of emittance growth in the RF photoinjector and the simulation, a new method to eliminate the RF effect is proposed for the thermal emittance measurement in RF photoinjector. Error of measurements is not included, and the space charge effect is also ignored on the condition of the low charge operation mode.
