摘要
本文研究了S-25与NewS-25光阴极的光谱响应特性.在850～1000nm范围光谱响应的提高主要归因于阴极层较厚,具有较大的阴极结构参量和截止波长.这既体现了NewS-25光阴极的优越性,也代这表了多碱阴极的发展方向.
In this paper, spectral response characterization on S-25 and New S-25 photo-cathodes are studied. Since photocathode has thicker pliotocathode thickness, higher photocathode structure parameter and spectral response cut-off wavelength, phot oca-thode sensitivity between 850 and 1000nm is improved. The improvements repres ent the superiority of New S-25 photooathode as well as a new direction of multialkali photocathodes.
