Abstract
The EXO-200 experiment searched for neutrinoless double-beta decay of 136Xe with a single-phase liquid xenon detector. It used an active mass of 110 kg of 80.6%-enriched liquid xenon in an ultra-low background time projection chamber with ionization and scintillation detection and readout. This paper describes the design and performance of the various support systems necessary for detector operation, including cryogenics, xenon handling, and controls. Novel features of the system were driven by the need to protect the thin-walled detector chamber containing the liquid xenon, to achieve high chemical purity of the Xe, and to maintain thermal uniformity across the detector.
Additional Information
EXO-200 is supported by DoE and NSF in the United States, NSERC in Canada, SNF in Switzerland, IBS in Korea, RFBR (18-02-00550) in Russia, DFG in Germany, and CAS and ISTCP in China. EXO-200 data analysis and simulation uses resources of the National Energy Research Scientific Computing Center (NERSC). We gratefully acknowledge the KARMEN collaboration for supplying the cosmic-ray veto detectors, and the WIPP for their hospitality. We thank Randy Elmore of WIPP for the initial idea of the thermal store. We thank SDMS for their commitment during the construction of the cryostat, and Sheedy Drayage for the careful shipment of the experiment to the WIPP site. We thank Carriaga Machine for onsite support during installation and operations. Finally, we thank H. Mong and W. Jarratt for assistance with the preparation of figures.Additional details
