Abstract: | Photoelectron extraction efficiency is a key parameter in gaseous detectors design requiring CsI photocathodes, particularly in pressurized applications for rare event experiments. Within this work we report on our measurements of the photoelectron extraction efficiency from a CsI photocathode into argon and xenon up to 10 atm. It is demonstrated that the photoelectron extraction efficiency is independent from pressure when scaling the electric field accordingly. This measurement provides experimental validation to the Monte Carlo predictions. |
