Using Na-22 And( 83m)Kr To Calibrate And Study The Properties Of Scintillation In Xenon-Doped Liquid Argon

We have measured the properties of scintillation light in liquid argon doped with xenon concentrations from 165 ppm to 10,010 ppm using a Na-22 source. The energy transfer processes in the xenon-doped liquid argon are discussed in detail, and a new waveform model is established and used to fit the average waveform. The time profile of the scintillation photon in the xenon-doped liquid argon and of the TPB emission are presented. The quantities of xenon-doped are controlled by a Mass Flow Controller which is calibrated via a Redusial Gas Analyzer to ensure that the xenon concentration is accurate. In addition, a successful test of Kr-83m as a calibration source has been implemented in the xenon-doped liquid argon detector for the first time. By comparing the light yield of the Na-22 and Kr-83m, it can be concluded that the scintillation efficiency is almost same over the range of 41.5 keV to 511 keV.
