“…The obtained results are helpful for monitoring drift properties, gain stability, and gas purity of the detector of the PandaX-III experiment during commissioning. The technique will also be applied to other gaseous TPCs, such as low-background alpha detectors [31]. The method may be of interest to TPC detectors with 𝑡 0 for validation of timing measurements.…”

We report the calibration of a gaseous Time Projection Chamber based on Micromegas charge readout modules with cosmic ray muons, utilizing their penetrating power and relatively uniform energy deposition per unit length. Muon events were selected through track reconstruction to characterize detector performances, such as the drift velocity, electron lifetime, detector gain, and electric field distortion. The evolution of detector performances over a 50-day data-taking cycle was measured with the muon calibration method. For instance, the drift velocity degraded from 3.40 ± 0.07 cm/μs to 3.06 ± 0.06 cm/μs without gas purification, and then recovered with gas purification. A 137Cs calibration source was also placed inside the detector as a reference for muon calibrations.
