论文摘要
在高加速梯度上运行的CW光注射器有望彻底改变科学和应用的许多领域。他们可以为新一代单色X射线无电子激光器，高亮度强子束或新一代微芯片生产建立基础。在这封信中，我们报告了具有$ \ textrm {csk} _ {2} \ textrm {sb} $ photocathode的纪录的超导射频射频枪支。该枪正在产生高电荷电子束（最多10 nc/bunch）和低横向发射量，同时用单个光电极运行数月。这项成就开启了一个新时代，以产生高功率梁的平均亮度非常高。
CW photoinjectors operating at high accelerating gradients promise to revolutionize many areas of science and applications. They can establish the basis for a new generation of monochromatic X-ray free electron lasers, high brightness hadron beams, or a new generation of microchip production. In this letter we report on the record-performing superconducting RF electron gun with $\textrm{CsK}_{2}\textrm{Sb}$ photocathode. The gun is generating high charge electron bunches (up to 10 nC/bunch) and low transverse emittances, while operating for months with a single photocathode. This achievement opens a new era in generating high-power beams with a very high average brightness.
