Precise Measurement and Control of Radon Progeny on Detector Surfaces
C. B. Z. Luo, C. Guo, L. P. Xiang +5
In low-background particle physics experiments, surface deposition of radon progeny presents a significant background challenge. To characterize this contamination, a high-sensitiv…
Search for Light-Mass Fractionally Charged Particles in Space with DAMPE Experiment
F. Alemanno, Q. An, P. Azzarello +144
Free Fractionally Charged Particles (FCPs) are predicted by some theories beyond or extended to the standard model. FCPs have been widely searched for by underground and space-base…
Diverse properties of electron Forbush decreases revealed by the Dark Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +147
The Forbush decrease (FD) of cosmic rays is an important probe of the interplanetary environment disturbed by solar activities. In this work, we study the properties of 8 FDs elect…
Measurement of radon concentration in the output water of the 100~t/h ultrapure water system at the Jiangmen Underground Neutrino Observatory
C. B. Z. Luo, Q. Tang, C. Guo +7
The Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton multi-purpose low background liquid scintillator detector, was proposed primarily to determine the neutrino mass ord…
Investigation of hadronic cross sections of cosmic ray carbon and oxygen on BGO from 200 GeV to 10 TeV energy at the DAMPE experiment
F. Alemanno, Q. An, P. Azzarello +143
The Dark Matter Particle Explorer (DAMPE) has made significant progress in measuring the fluxes of cosmic rays. These new measurements are pivotal in advancing our understanding of…
