The DARWIN project aims to build and operate a next-generation observatory for dark matter and neutrino physics, featuring a time projection chamber with a proposed active target of 40 t of liquid xenon.
- As an R&D facility to test fundamental components of the future detector, Xenoscope, a full-scale vertical demonstrator with ~400 kg of liquid xenon and up to 2.6 m electron drift length, was built at the University of Zurich.
- Its main objective is to demonstrate electron drift over unprecedented distances in liquid xenon - first in a purity monitor setup with charge readout, followed by a dual-phase time projection chamber.
- In this second phase, an array of 48 VUV4 MMPCs from Hamamatsu (model S13371-6050CQ-02) with a 12-channel readout will be placed above the liquid xenon column and operated as a light readout for the secondary proportional scintillation signals coming from extracted electrons in the time projection chamber.
