Abstract
Abstract
The Deep Underground Neutrino Experiment (DUNE) is a next
generation experiment aimed to study neutrino oscillation. Its
long-baseline configuration will exploit a Near Detector (ND) and a
Far Detector (FD) located at a distance of ∼1300 km. The FD
will consist of four Liquid Argon Time Projection Chamber (LAr TPC)
modules. A Photon Detection System (PDS) will be used to detect the
scintillation light produced inside the detector after neutrino
interactions. The PDS will be based on light collectors coupled to
Silicon Photomultipliers (SiPMs). Different photosensor
technologies have been proposed and produced in order to identify
the best samples to fullfill the experiment requirements. In this
paper, we present the procedure and results of a validation campaign
for the Hole Wire Bonding (HWB) MPPCs samples produced by Hamamatsu
Photonics K.K. (HPK) for the DUNE experiment, referring to them as
`SiPMs'. The protocol for a characterization at cryogenic
temperature (77 K) is reported. We present the down-selection
criteria and the results obtained during the selection campaign
undertaken, along with a study of the main sources of noise of the
SiPMs including the investigation of a newly observed phenomenon in
this field.
