Abstract

ICARUS is the largest imaging LAr TPC ever operated. During its LNGS run on the CNGS neutrino beam, from 2010 to 2013, produced some thousands neutrino events of unprecedented quality. This was possible thanks its mechanical precision and stability, liquid argon purity and electronics front-end and DAQ. Actually ICARUS T600, in view of its operation at FNAL on the SBN neutrino beam, is undergoing a major overhauling that implies cathode mechanics improvement, additional PMTs installation and a new electronics front-end and DAQ. This electronics implements a new architecture, integrated onto the flange proprietary design, and a new front-end that improves S/N and induction signals treatment. This issue will be presented in detail together with data recently recorder at CERN in the FLIC, 50 litres, LAr facility.

Highlights

ICARUS is the largest imaging Liquid Argon Time Projection Chamber (LAr TPC) ever operated
ICARUS-T600 searched for a possible LSND-like effect through the appearance of νe in the CNGS νμ beam; in the ∼ 7.9 1019 pot exposure, seven νe events have been observed while the expected background was ∼ 8.5
The two T600 modules were transported to FNAL in July 2017 and are currently being installed in the far position at the FNAL Booster beam; the detector commissioning is expected in the summer of 2018

Summary

The ICARUS T600 detector

EPJ Web of Conferences total volume results 760 tons of ultra-pure LAr. The TPCs are characterized by a 1.5 m drift length, over which a uniform electric field ED = 500 V/cm is maintained. The anode plane is made of three parallel wire planes, 3 mm apart, biased in such a way to have ionization electrons going around the wires of the first two (Induction) planes, and being collected on the third, Collection plane. An array of 74 PMTs has been located and used to collect the scintillation light produced in the LAr and this signal is the basis for the trigger of the detector [2, 3]. A more detailed description of the ICARUS T600 detector can be found in [4,5,6]
