Study Of Xe-Doping To Lar Scintillator

Liquid argon (LAr) is an inorganic scintillator widely used in experimental physics. In this paper, the experimental study of Xe-doping as a volume-distributed wavelength shifter in LAr is described. The efficiency of light collection and the pulse shapes has been measured for the concentrations of Xe in Ar from few ppm to 24(-9)(+16) Pppm. The stability of the data has been measured for the 24(-9)(+16) Pppm concentration during 31 hours.
