摘要：
The photoelectron-collection efficiency from photocathodes in noble gases and methane is experimentally investigated. The ratio between the number of transmitted photoelectrons in the gas media and in vacuum is determined as a function of the applied reduced electric field Elp, where p is the gas pressure. Results are presented for He, Ne, Ar, Xe, Kr and CH4. (C) 2007 Elsevier B.V. All rights reserved.
