Design and construction of Xenoscope -- a full-scale vertical demonstrator for the DARWIN observatory

Understand

The DARWIN observatory is a proposed next-generation experiment to search for particle dark matter and other rare interactions.

• It will operate a 50 t liquid xenon detector, with 40 t in the time projection chamber (TPC).
• To inform the final detector design and technical choices, a series of technological questions must first be addressed.
• Here we describe a full-scale demonstrator in the vertical dimension, Xenoscope, with the main goal of achieving electron drift over a 2.6 m distance, which is the scale of the DARWIN TPC.
