Spatially uniform calibration of a liquid xenon detector at low energies using Kr-83m
Original language description
A difficult task with many particle detectors focusing on interactions below similar to 100 keV is to perform a calibration in the appropriate energy range that adequately probes all regions of the detector. Because detector response can vary greatly invarious locations within the device, a spatially uniform calibration is important. We present a new method for calibration of liquid xenon (LXe) detectors, using the short-lived Kr-83m. This source has transitions at 9.4 and 32.1 keV, and as a noble gaslike Xe, it disperses uniformly in all regions of the detector. Even for low source activities, the existence of the two transitions provides a method of identifying the decays that is free of background. We find that at decreasing energies, the LXe light yield increases, while the amount of electric field quenching is diminished.
