Silicon photomultipliers (SiPM) are the baseline option as the photodetector technology for the dual-radiator Ring-Imaging Cherenkov (dRICH) detector at the future Electron-Ion Collider (EIC) in the Electron-Proton/Ion Collider experiment (EPIC). A SiPM-based readout offers important advantages being cheap devices, highly efficient and insensitive to high magnetic field (~ 1 T at the expected...
Silicon photomultipliers (SiPMs) are suitable for scintillation light detectors used in multiple rare searches experiments. The SiPMs are distributed on a hierarchical structure of mini-tiles, multiple readout channels tiles, integrated on staves, and arranged in a form of a barrel of detectors with large area of SiPM, looking inside the volume filled with noble liquid. In addition to...
The Light-only Liquid Xenon (LoLX) experiment is designed to study the properties of light emission and transport in liquid xenon (LXe) using Hamamatsu VUV4 Silicon Photo Multiplier (SiPM) modules. LoLX is also being used to investigate the timing structures of scintillation and Cherenkov light production in LXe and provide a better understanding of the effects of external cross-talk between...
The DarkSide program aims to a WIMP direct detection using a dual phase argon time projection chamber. The next generation experiment, DS-20k, will be a detector in excess of 20 tonnes of fiducial mass. A pivotal aspect to the sensitivity of the experiment is its light detection technology. The DarkSide collaboration decided to adopt a new family of photo-sensors called Silicon...
The MIP Timing Detector (MTD) is a new detector being developed for the CMS upgrade for the High-Luminosity LHC era. The detector will bring the capability of precisely measuring the production time of particles produced in proton-proton collisions. In particular, the MTD will allow for the disentangling of the estimated 200 nearly simultaneous pileup vertices occurring in the interaction...
A metalens is an emerging type of flat optical metamaterial that presents several advantages over a traditional lens, such as reduced cost and reduced bulkiness. We developed a set of software tools and fabrication procedures for the rapid development and characterization of new metalens designs. A large field-of-view centimeter-scale metalens was fabricated, and its performance compared with...
Silicon PhotoMultipliers (SiPMs) are increasingly used in next-generation, large area particle physics experiments to achieve single-photon resolution [1, 2, 3]. An array of Single Photon Avalanche Diodes (SPADs) within the SiPM reacts to incident photons through an avalanche process that creates a measurable current flow. This avalanche process generates secondary photons which must be...
The next generation of experiments for rare-event searches based on skipper Charge Coupled Devices (skipper-CCDs) will bring new challenges for the packaging and read-out of the detectors. Scaling the active mass and simultaneously reducing the experimental backgrounds in two orders of magnitude will require a novel high-density Silicon-based package, that must be massively produced and...
Non-destructive readout capability of the Skipper Charge Coupled Device (CCD) has been proven to be a powerful technique to reduce the noise limitation of conventional silicon devices even to levels that allow single-photon or single-electron counting. The noise reduction is achieved by spending extra time taking several measurements of the same pixel charge. The technique requires minimal...
We present a multiplexed analog readout electronics system for Skipper-CCDs. The system allows for sub-electron noise-level operation while maintaining a minimal number of acquisition channels. In addition, it requires low-disk storage and low-bandwidth data transfer with zero added multiplexing time during the simultaneous operation of thousands of channels. We describe the implementation and...
Projective readout technologies currently used in Liquid Argon Time Projection Chambers come with a set of challenges from the construction of the wire planes themselves to the continuous readout of the system required to accomplish the physics goals of proton decay searches and supernova neutrino sensitivity. Additionally, the reconstruction techniques required for these projective readouts...
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...
Here we describe the physics behind the pixel based accelerated aging method of the microchannel plate-photomultiplier tubes (MCP-PMTs) developed at the University of Texas at Arlington. In this fast lifetime testing method, a highly localized region of the MCP-PMT is exposed to photons at a high repetition rate. The pixel-based testing method was inspired by our previous research that has...
In this talk I will present my most recent results of single photoelectron detection with an Incom Inc. LAPPD (LAPPD 38). The single photoelectron signal is used to determine the characteristic dependence of gain on MCP and photocathode voltages. It is also used to calibrate the LAPPD in units of number of photoelectrons for Cherenkov light detection.
I will also discuss my incipient work on...
Various ring imaging Cherenkov sub-systems are being proposed in EIC detector for hadron identification with momenta up to 50 GeV/c. It is critical to have a reliable highly pixelated readout sensor working in the high magnetic field environment. Optimization of the photosensor design for high magnetic field tolerance, precision timing resolution, and pixelated readout was performed at Argonne...
Large Area Picosecond Photodetectors (LAPPDs) are micro-channel based photosensors featuring hundreds of square centimeters of sensitive area in a single package and timing resolution on the order of 50 ps for a single photon detection. However, until recently LAPPDs did not exist in finely pixelated 2D readout configurations that in addition to the high-resolution timing would also provide...
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...
At present a single pixel or camera plane capable of detecting single photons with high dynamic range, time resolution approaching 10ps, and frame rates above 100’s MHz are unavailable. MicroChannel Plate (MCP) based imaging tubes or PMT have superior time resolution compared with PMT, and performance in magnetic fields due to secondary electrons with laterally confined paths to the anode. On...
Researchers at IHEP have conceived two types of MCP-PMTs for photon detection in particle physics. One is the 20-inch Large MCP-PMT (LPMT) with small MCP units in the large area PMTs for neutrino detection. This LPMT has already been mass-produced in more than 15K pieces in the JUNO experiment and has also been evaluated by the PMT group in LHAASO and HyperK. The other is the 2-inch Fast...
Micro Channel Plate (MCP) Photomultiplier Tubes (MCP-PMTs) are photon detectors with many useful characteristics, such as high gain, single photon detection efficiency, precise timing resolution, and the capability of operating in strong magnetic fields without performance degradation. The quantum efficiency of the photocathode of the MCP-PMTs, however, is known to degrade due to “positive-ion...
New live-cell chemical imaging techniques became feasible due to the progress in superconducting quantum detectors. One can decompose IR radiation coming from the region of the single cell dimensions over 1000 or more spectral channels and timestamp IR photons arriving to the detector array with about 10 ps time resolution. This opens ways to use IR luminescence spectroscopy, which can be...
