Noble liquid time projection chambers (TPCs) are of interest for experiments in the quest to answer some most basic questions in both particle and nuclear physics. The charge and light in both LAr and LXe in response to particles of interest are at the limits of detection sensitivity and accuracy of their respective charge sensing electrodes and light sensors, such as silicon photomultipliers...
The Deep Underground Neutrino Experiment (DUNE) is a long baseline neutrino experiment designed to mainly investigate oscillation parameters, supernova physics and proton decay. Its far detector will be composed of four liquid argon time projection chamber (LArTPC) underground modules, in South Dakota-USA, which will detect a neutrino beam produced at Fermilab, 1300 km away, where a near...
Liquid argon is commonly used as a detector medium for neutrino physics and dark matter experiments in part due to its copious scintillation light production in response to its excitation and ionization by charged particle interactions. As argon scintillation appears in the vacuum ultraviolet (VUV) regime and is difficult to detect, wavelength-shifting materials are typically used to convert...
Photon detectors which are sensitive to the vacuum ultraviolet (VUV) scintillation light produced in noble element particle detectors is an area of active research and development. In particular, searching for photoconductive materials which are capable of converting VUV light to charge could open the doorway to a potentially game changing solution of an integrated charge and light (Q+L)...
One of the important variables to optimize for a successful detection of the neutrinoless double-beta decay is the energy resolution at its Q-value. nEXO is a proposed tonne-scale experiment aiming to search such decay for the isotope Xe-136. It exploits the anticorrelation between ionization and scintillation of xenon to improve the ultimate energy resolution. A major factor affecting the...
In recent decades, argon-based particle detectors have become a widely-used technology for numerous applications, including dark matter searches and neutrino measurements. For these detector designs, WaveLength Shifters (WLS) such as tetraphenylbutadiene (TPB) are used to shift argon's scintillation light from the hard UV (128 nm) to visible wavelengths. In particular, the use of...
The Short-Baseline Near Detector (SBND) is a Liquid-Argon Time Projection Chamber (LArTPC) currently under construction at Fermilab. SBND is one of three detectors that make up the Short Baseline Neutrino (SBN) program, which aims to investigate the excess of low-energy electron-like events observed by the MiniBooNE and LSND experiments, as well as perform high-precision neutrino-argon cross...
