摘要：Calibration program:Internal/external ER peaks:Detector uniformity corrections，Light/charge collection parameters.Low rate AmBe neutron source:Simulate DM NR signal.CH3T injection: tritium beta decays，Simulate ER background.Single electron gain:Identify smallest S2 in the data.Fitted with two Gaussians (with S2 rec. efficiency taken into account).Extracting detector parameters:Gaussian fits to all ER peaks in data.Linear fit in S1/E vs S2/E to extract PDE and EEE.
