Measurement of solar neutrino flux with the new PandaX-4T data
PandaX Collaboration, Peiyuan Chen, Wei Chen +104
We report a new measurement of the solar proton--proton () neutrino flux via neutrino--electron elastic scattering using the PandaX-4T Run 2 data set collected between 2024 and…
Probing scalar-neutrino and scalar-dark-matter interactions with PandaX-4T
PandaX Collaboration, Tao Li, Zihao Bo +113
Scalar-mediated interactions may exist among neutrinos, dark matter particles, or between the two. Double -decay experiments provide a powerful tool to probe such exotic intera…
A MIDAS-based Data Acquisition System for Gaseous Detectors
Yuanchun Liu, Tao Li, Yu Chen +4
We present a data acquisition~(DAQ) software based on the MIDAS framework, specifically for gaseous detectors to support the detector deployments and applications. It implements a…
Precise Xe Double Beta Decay Measurement in PandaX-4T with Implications on the Nuclear Matrix Elements and Majorons
PandaX Collaboration, Zhe Yuan, Zihao Bo +111
The continuous spectrum of double beta decay () provides a sensitive probe to test the predictions of the standard model and to search for signatures of new physics beyond it…
Performance Test and Circuit Simulation for R12699-406-M4 Photomultiplier Tube Base
Houqi Huang, Peiyuan Chen, Ke Han +8
The next-generation liquid xenon experiments like PandaX-xT target an energy range from sub-keV to multi-MeV to address the requirement of multiple physics searches. The Hamamatsu…
The throttling refrigeration system for the large cooling power recovery of the PandaX-xT cryogenic distillation system for radon removal
Shunyu Yao, Zhou Wang, Kangkang Zhao +15
In order to solve the continuous large cooling power supply problem (20 kW) for the radon-removal cryogenic distillation system, which operates at high liquid ffow rate of 856 kg/h…
