Abstract :
Scintillation light and ionization yields in pure xenon and xenon doped with various concentration of methane (0.2-2%) have been measured as a function of the reduced electric field (E/N) from 0 to 4×10-18 Vcm2 at a pressure of 2.6 MPa. The measurements of photons and electrons have been made in gaseous xenon excited by 241Am alpha particles. High purity xenon was used to fill a high-pressure xenon chamber equipped with MgF2 window coupled to a photomultiplier tube (PMT). The scintillation light in xenon-methane mixture is observed to decrease as the concentration of methane increases.
