ARGONCUBE – Design, Construction and Test of the Liquid Argon Near Detector for the DUNE Neutrino Experiment

In association with the giant 10 kton DUNE (Deep Underground Neutrino Experiment) being built at Homestake there will need to be a smaller near detector at Fermilab. The Sheffield group is collaborating with Bern University to build and test a liquid argon version of this with responsibility to design, build and test a 1.0m x 0.5m time projection chamber device. The project involves contributing to the design, installation and operation of this with Bern colleagues and subsequent analysis of particle data following transfer to a test beam at CERN. There will be opportunity also to conduct support detector R&D using the Sheffield liquid argon test-stand facility to study upgrade options for the readout, including comparison of silicon photo-sensors, cryogenic photomultipliers, GEMs and micromegas devices. Critical measurements are anticipated of liquid argon parameters including electron drift. There will be chance of long term attachment (6-12 months) in Bern or at CERN in Switzerland.
