Description
The photoelectron-collection efficiency from photocathodes in noble gases is
studied. The case of electron emission induced by a Hg lamp in a CsI
photocathode is analyzed. The ratio between the number of transmitted
photoelectrons in the gas media and in vacuum is determined, and results
are presented for He, Ne, Ar, Xe, Kr, and CH4 as a function of the applied
reduced electric field E/p, where p is the gas pressure.
