Abstract
Some novel ideas of ionization-electron and scintillation-photon sensing concepts in single-phase noble-liquid detectors are presented. They rely on immersed micro-structured...
The bubble-free Liquid Hole-Multiplier (bf-LHM) has been proposed as a novel sensor for recording both scintillation- and electroluminescence-photons in dual-phase detectors. The new concept follows that of the bubble-assisted one investigated over the past years.
In this contribution, we will discuss the progress made with this new, simpler concept – in which the gas bubble is replaced by...
We describe a novel concept for dual-phase noble liquid detectors, the Floating Hole Multiplier (FHM). It consists of a perforated electrode freely floating on the surface of the liquid. The concept has been validated with a Thick Gas Electron Multiplier (THGEM) on the surface of liquid xenon. First experimental results will be reported showing that the electrons, liberated in liquid xenon due...
Large scintillation gaps are desirable for electroluminescence chambers with ultimate energy resolution and single-electron counting characteristics, whereas large-area amplification structures are needed for next-generation ton-scale experiments. We present systematic studies of a custom designed structure (Field-Assisted Transparent Gas Electroluminescence Multiplier, or FAT-GEM), consisting...
The Short Baseline Neutrino (SBN) program at the Fermi National Laboratory in the US is an extensive experimental programme based on three Liquid Argon Time Projection Chambers (LAr-TPCs) aiming at searching for sterile neutrino(s), whose existence is one of the fundamental open questions of neutrino physics. The SBN program aims to study neutrino oscillations and interactions in the...
SBND is the near detector of the Short Baseline Neutrino program at Fermilab. Its near location (110 m) to the neutrino source and relatively large mass (112 ton active volume) will allow studying neutrino interactions on argon with unprecedented precision.
This talk focuses on the SBND Photon Detection System. It represents a major R&D opportunity for the LArTPC technology. Its design is a...
The DARWIN project aims to build and operate a next-generation observatory for dark matter and neutrino physics, featuring a time projection chamber (TPC) with a proposed active target of 40 t of liquid xenon (LXe). As an R&D facility to test fundamental components of the future detector, Xenoscope, a full-scale vertical demonstrator with 350 kg of LXe and up to 2.6 m electron drift length was...
Compact large-area dielectric photon detectors ensure modular noble liquid detectors can sense scintillation light signals for triggering and reconstruction purposes with minimal decreases to the overall target volume of the module. ArCLight is a small volume, sizeable sensitive area detector that consists of a light trap covered in a thin layer of TPB that can be placed along a time...
The Deep Underground Neutrino Experiment (DUNE) will be using a liquid argon time projection chamber (LAr TPC) with optically separated modules in the Near Detector (ND) complex. A prototype experiment for these modules, DUNE ND-LAr 2x2, is currently commissioning and constructing four test modules. These modules detect ionization charge through a pixel-based readout and scintillation light...
The Deep Underground Neutrino Experiment (DUNE) is be a massive long baseline (1300 km) neutrino experiment that aims to shade light on some of the major open questions in neutrino physics. The neutrino beam measurements will be performed by a near detector (ND) and far detector (FD). The far detector will consist of four modules, installed 1,5 km deep underground, based Liquid Argon Time...
