摘要
The results of a systematic investigation of the properties of CsI and CsI-TMAE photocathodes, in the spectral range of 150-200 nm, are presented. The measurements were carried out in high vacuum and in CH4 atmosphere. Effects of the photocathode regeneration and the enhancement of the quantum efficiency due to temperature and TMAE adsorption are observed. The stability of the TMAE effect was investigated and is discussed. A comparison is given with different results of other groups.
