Commissioning of the Xenoscope Time Projection Chamber for the DARWIN Dark Matter Observatory

POSTER

Abstract

Xenoscope at the University of Zurich is an R\&D platform for the DARWIN observatory. It aims to validate electron drift in a 2.6-meter tall TPC and optimize purification rates for DARWIN's goals. After installing the TPC in the Xenoscope cryostat and filling it with about 350 kg of LXe, various subsystems were commissioned. This report focuses on the detector filling, operation, and calibration of the level meter sensors to achieve optimal conditions for dual-phase TPC operation.
