Keywords: | Photoemission; Noble gases; Methane; Electron backscattering | Issue Date: | 2007 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 581:1-2 (2007) 190-193 | Abstract: | 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 E/p, where p is the gas pressure. Results are presented for He, Ne, Ar, Xe, Kr and CH4. | URI: | https://hdl.handle.net/10316/4346 | DOI: | 10.1016/j.nima.2007.07.075 | Rights: | openAccess |
