Identification of anomalous fast bulk events in a p-type point-contact germanium detector
文献摘要:
The ultralow detection threshold,ultralow intrinsic background,and excellent energy resolution of p-type point-contact germanium detectors are important for rare-event searches,in particular for the detection of direct dark matter interactions,coherent elastic neutrino-nucleus scattering,and neutrinoless double beta decay.Anomalous bulk events with an extremely fast rise time are observed in the CDEX-1B detector.We report a method of extracting fast bulk events from bulk events using a pulse shape simulation and reconstructed source experiment signature.Calibration data and the distribution of X-rays generated by intrinsic radioactivity verified that the fast bulk experi-enced a single hit near the passivation layer.The perfor-mance of this germanium detector indicates that it is capable of single-hit bulk spatial resolution and thus pro-vides a background removal technique.
