Wed, 21 Dec 2022 14:15:52 GMT (1862kb,D) | Abstract: | The XENONnT detector uses the latest and largest liquid xenon-based time
projection chamber (TPC) operated by the XENON Collaboration, aimed at
detecting Weakly Interacting Massive Particles and conducting other rare event
searches. The XENONnT data acquisition (DAQ) system constitutes an upgraded and
expanded version of the XENON1T DAQ system. For its operation, it relies
predominantly on commercially available hardware accompanied by open-source and
custom-developed software. The three constituent subsystems of the XENONnT
detector, the TPC (main detector), muon veto, and the newly introduced neutron
veto, are integrated into a single DAQ, and can be operated both independently
and as a unified system. In total, the DAQ digitizes the signals of 698
photomultiplier tubes (PMTs), of which 253 from the top PMT array of the TPC
are digitized twice, at $ imes10$ and $ imes0.5$ gain. The DAQ for the most
part is a triggerless system, reading out and storing every signal that exceeds
the digitization thresholds. Custom-developed software is used to process the
acquired data, making it available within $mathcal{O}left(10 ext{ s}
ight)$
for live data quality monitoring and online analyses. The entire system with
all the three subsystems was successfully commissioned and has been operating
continuously, comfortably withstanding readout rates that exceed $sim500$ MB/s
during calibration. Livetime during normal operation exceeds $99\%$ and is
$sim90\%$ during most high-rate calibrations. The combined DAQ system has
collected more than 2 PB of both calibration and science data during the
commissioning of XENONnT and the first science run. | Source: | arXiv, 2212.11032 | Services: | Forum | Review | PDF | Favorites |
