Light/charge readout (PMTs, SiPM, WLS, electronics, etc.)
Presentation
We present the performances and characterization of an array made of S13370-3050CN (VUV4 generation) Multi-Pixel Photon Counters manufactured by Hamamatsu and equipped with a low power consumption preamplifier for operations in liquid xenon environment. The electronics is designed for the readout of a 8×8 matrix of individual photosensors and it is based on a single operational amplifier...

Presentation
The nEXO collaboration is designing a 5-tonne xenon time projection chamber (TPC) using enriched Xe-136 isotope to search for neutrinoless double beta decays. Both the light and charge signals from interactions in the TPC will be collected. The light signals are planned to be detected with silicon photomultipliers (SiPMs). Comprehensive efforts have been made on SiPM performance...

Light/charge readout (PMTs, SiPM, WLS, electronics, etc.)
Presentation
The Silicon Geiger Hybrid Tube (SiGHT) is a novel photosensor designed for use in ultra low background experiments operating at low temperatures.
Thanks to an electric drift field, electrons, produced by the conversion of the incoming photons onto a hemispherical photocathode, are accelerated and focused onto a Silicon Photomultiplier which provides single stage electron multiplication....

Light/charge readout (PMTs, SiPM, WLS, electronics, etc.)
Presentation
In this talk, I will present work being done at Davis to develop and utilize SensL silicon photomultiplier (SiPM) arrays. First, I will talk about the development of a UV-sensitive SiPM system suitable for deployment in noble element time projection chambers. We show that device performance is not compromised in high electric fields nor at low temperatures.
Second, I will talk about arrays...

Light/charge readout (PMTs, SiPM, WLS, electronics, etc.)
Presentation
Liquid argon time projection chambers (LArTPCs) are ideally suited to perform long baseline neutrino experiments aiming to measure CP violation in the lepton sector, and determine the ordering of the three neutrino mass eigenstates.
LArTPCs have used projective wire readouts for charge detection since their conception in 1977.
However, wire readouts are notoriously fragile and therefore a...

Presentation
The CAPTAIN (Cryogenic Apparatus for Precision tests of Argon Interactions with Neutrinos) experiment is a five-ton liquid Argon Time Projection Chamber at Los Alamos National Laboratory. CAPTAIN is designed to make measurements of liquid argon interactions relevant to neutrino physics in particular for the proposed DUNE (Deep Underground Neutrino Experiment) underground detector. In addition...

Light/charge readout (PMTs, SiPM, WLS, electronics, etc.)
Presentation
The Deep Underground Neutrino Experiment (DUNE) is a 40-kton underground liquid argon (LAr) time-projection-chamber (TPC) detector, for long-baseline neutrino oscillation studies and for neutrino astrophysics and nucleon decay searches. Photon detector systems embedded within the LAr TPC add precise timing capabilities for non-beam events. The ProtoDUNE dual phase detector will consist of a...
