On May 31st 2021, the first technical paper describing our Xenoscope facility was posted on arXiv. Xenoscope is a full-scale vertical demonstration platform which will be used to develop and test key technologies necessary to the realisation of the future DARWIN observatory.
Our main objective is to demonstrate the drift of electrons over a distance of 2.6 m by investigating HV distribution and xenon purification methods. In this paper, we describe the different systems built into Xenoscope, such as the cryogenic and purification systems, two recovery and storage systems, the slow control, the purity monitor and the TPC. We also report on the successful commissioning of the Xenoscope facility. The first full run was performed over 40 days of continuous operation with ~80 kg of LXe. Next, Xenoscope will be outfitted with the first phase of the experiment, the purity monitor, by the end of Q2 2021.
