Description
A giant (10-50 kt) liquid argon TPC has been proposed as the detector for an underground observatory for the study of neutrino oscillations, neutrino astrophysics and proton decay.
This detector has excellent tracking and calorimetric capabilities much superior to currently operating neutrino detectors.
LBNO-DEMO (WA105) is a large demonstrator of the double phase liquid argon TPC based on the GLACIER design, with a 6$\times$6$\times$6~m$^3$ (appr. 300t) active volume.
The TPC will be built inside a tank based on industrial LNG technology. Electrons produced in the liquid argon are extracted in the gas phase. Here, a readout plane based on LEM detectors provides amplification before the charge collection onto an anode plane with strip readout. PMT located on the bottom of the tank containing the liquid argon provide the readout of the scintillation light.
This demonstrator is an industrial prototype of the design proposed for a large underground detector. WA105 is under construction at CERN and will be exposed to a charged particle beam (0.5-20 GeV/c) in the North Area in 2018.
The data will provide necessary calibration of the detector performances and benchmark sophisticated reconstruction algorithms.
This project is a crucial milestone providing feedback for the long baseline neutrino program, including projects like LBNO and DUNE.
