Readout electronics and data acquisition system of PandaX-4T experiment

Understand

PandaX-4T is a dark matter direct detection experiment located in China jinping underground laboratory.

• The central apparatus is a dual-phase xenon detector containing 4 ton liquid xenon in the sensitive volume, with about 500 photomultipliers instrumented in the top and the bottom of the detector.
• In this paper we present a completely new system of readout electronics and data acquisition in the PandaX-4T experiment.
• Compared to the one used in the previous PandaX dark matter experiments, the new system features triggerless readout and higher bandwidth.
