Abstract:
The monochromat ic photocurrent of photocathode actually reflects it s quantum yield under the monochromat ic light . T he principle measuring monochromat ic photocurrent and factors influencing quantum yield are expounded in this paper . The system measuring mult-i parameter of photocathodes is presented . The system can on-line measure and deal w ith the monochromatic photocurrent of cathodes. T he measured curves are valuable to analyzing and direct ing technolog y producing photocathodes . The photoelectrons escaped depth can be est-i mated by the curves . The results measuring the parameters of cathodes in the glass tubes are g iven and analy zed .
