In this talk, we propose a detector concept called APEX (Aluminum Profiles with Embedded X-arapucas) for large LArTPC detectors by instrumenting large-area X-arapuca photon detectors on the entire LArTPC field cage. The photon detectors will cover four sides of a typical cuboid LArTPC volume like the DUNE VD module excluding the two anode planes, with a covered area of up to 2500m^2. The PoF...

Large Area Picosecond Photo-Detectors (LAPPDs) produced by Incom Inc. are the world’s largest commercially-available planar-geometry photodetectors based on microchannel plates (ALD-GCA-MCPs). It features a chevron pair of “next generation” large area MCPs produced by applying resistive and emissive Atomic Layer Deposition (ALD) coatings to borosilicate glass capillary array (GCA) substrates...

Vacuum-ultraviolet (VUV) light has applications in many areas of fundamental research and technology, including high-energy physics (HEP) experiments and especially those based on scintillation of noble elements (xenon and argon).

There has been increasing progress in using Low Gain Avalanche Detectors (LGADs) for HEP applications to obtain improved signal-to-noise ratio and temporal resolution compared to PIN diode arrays. However, the lack of a thin entrance window is a limiting factor for deploying LGADs in some applications. For instance, UV light from noble liquid scintillation, low-energy electrons in reaction...

Micro-channel plate photo-multiplier tubes (MCP-PMTs) have become ubiquitous and are widely considered potential candidates for next-generation high-energy physics experiments due to their picosecond timing resolution, ability to operate in strong magnetic fields, and low noise rates. A key factor determining the applicability of MCP-PMTs is their lifetime, mainly when used in high-event rate...

Amorphous selenium (a-Se) is a well-studied photoconductor utilized in both direct and indirect X-ray detection, with applications in medical, industrial, materials, and high-energy imaging; recent studies also highlight its potential for particle detection with noble elements. Amorphous Se exhibits many ideal properties for photodetection, with excellent conversion efficiency from the vacuum...

Liquid Argon Time Projection Chambers (TPC) are promising detectors for dark matter search due to their response uniformity, scalability to large target masses, and suitability for extremely low background operations. The DarkSide-20k experiment is a new dark matter detector under construction at Istituto Nazionale di Fisica Nucleare (INFN) Laboratori Nazionali del Gran Sasso (LNGS) that...

nEXO is a next-generation 5-tonne liquid xenon time projection chamber that will search for neutrinoless double beta decay (0$\nu\beta\beta$) of $^{136}$Xe with a projected half-life sensitivity of 1.35x10$^{28}$ years in 10 years of livetime. To achieve this sensitivity, the design goal of nEXO is $\leq$1% energy resolution at the Q$_{\beta\beta}$ endpoint value of 2.458 MeV. To reach this...

A critical element in all high-energy physics experiments is the signal transmission from the active elements to the data acquisition system. It is especially challenging in large volume detectors based on noble liquids that are extensively being used for dark matter and neutrino detection.
The topics of this contribution is the optical signal transmission of the signals acquired with...

We have proposed a method of construction and simulated the performance in TOPAS [1] of large-area microchannel plates (MCPs) assembled by stacking thin, patterned laminae on edge to form laminar microchannel plates (LMCPs$^\rm{TM}$) [2]. The laminae are first patterned with channels of arbitrary shape and size so that when stacked, they form pores as in a traditional MCP. The laminae are...

The next generation of ground and space-based cosmic surveys in the optical to near-IR regime require extremely sensitive, virtually noiseless detectors that are capable of counting single-photon or single-electron events. Skipper charge-coupled devices (CCDs) offer the ability to achieve deeply sub-electron read noise by exploiting the technique of non-destructive readout to independently...
