Abstract:
Precise measurement of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) is crucial for constraining the Standard Model, probing non-standard neutrino interactions and rejecting the background in dark matter detection. The two phase Liquid Xenon Time Projection Chamber (LXeTPC) achieves enhanced signal amplification and lower-energy thresholds, making it an ideal technology for CEvNS detection. The RELICS experiment utilizes the LXeTPC technology to detect neutrinos from a nuclear reactor in Taizhou, China. One of the key challenges in this new scenario is suppressing the dominant delayed-electron background from cosmic muons. This seminar will report the latest R&D progress of RELICS experiment on sub-keV level signal detection, as well as the main strategy to this background.
Biography:
Dr. Jijun Yang currently serves as the coordinator of the electronics and data acquisition (DAQ) system in the RELICS experiment. His research focuses on neutrino and dark matter detection. He obtained his Ph.D. from Shanghai Jiao Tong University in 2022. In 2017, he joined the PandaX collaboration working on dark matter and neutrino detection, and served as the on-site leader of the electronics and DAQ system during the PandaX 4T commissioning run. In 2024, as a postdoc at Westlake University, he worked on fast analysis of Rn 220 calibration for low energy electrical recoil and backscatter facility installation for low energy nuclear recoil calibration in XENONnT. He proposed and is responsible for developing the extended dynamic range readout electronics for rejecting the main backgrounds in RELICS experiment.
