Abstract: (IOP)
The PandaX-4T experiment is designed for multiple purposes,including searches for solar neutrinos, weakly interacting massiveparticles, and rare double beta decays of xenon isotopes. Theexperiment produces a huge amount of raw data that needs to bestored for related physical analyses in a wide energy range. Withthe upgrading of the PandaX-4T experiment, the doubled sampling rateresulted in a larger data size, which challenges both the cost andthe data processing speed. To address this issue, we propose a datareduction strategy by removing the noise tail of large signals anddownsampling the remaining parts of them. This strategy reduces therequirement for storage by 65% while increasing data processingspeed. The influences on physical analyses on different topics atdifferent energy regions are negligible.Note:
