摘要

本文研究了离子源相关真空条件下表面上的功函数和铯动力学的真空兼容原位测量探针(PRISM)的研制。功函数估计是基于测量激光照射探针表面后光电信号的起始点。此外，PRISM的独特设计使得它可以作为表面电离探针，也可以用于测量铯通量。此外，利用红外成像可以估计同一表面上铯的覆盖率。

Probe for in situ measurement of work function in correlation with cesium dynamics suitable for ion source applications

This paper deals with the development of a vacuum compatible probe for in situ measurement (PRISM) of work function and cesium dynamics on a surface under ion source relevant vacuum conditions. The work function estimation is based on the measurement of the onset of the photoelectric signal after laser irradiation on the caesiated surface of the probe. Moreover, the PRISM is uniquely designed such that it can operate as a surface ionisation probe also for the measurement of cesium flux. In addition, cesium coverage on the same surface can be estimated using infrared imaging.
