光电阴极是下一代超高亮度光电注入器的限制因素。我们研究了超导射频枪腔低温环境中超导 Pb 阴极的行为，以测量量子效率、其空间分布和功函数。我们还将讨论阴极表面污染物如何改变光电阴极以及枪腔的性能，并讨论去除这些污染物的可能性。
Photocathodes are a limiting factor for the next generation of ultrahigh brightness photoinjectors. We studied the behavior of a superconducting Pb cathode in the cryogenic environment of a superconducting rf gun cavity to measure the quantum efficiency, its spatial distribution, and the work function. We will also discuss how the cathode surface contaminants modify the performance of the photocathode as well as the gun cavity and we discuss the possibilities to remove these contaminants.
