6. Correlated noises for NUV-HD-Cryo SiPMs

Alessandro Razeto (INFN)

9/22/22, 11:40 AM

Signal reconstruction and identification (analysis methods, simulations)

Presentation

Silicon Photomultipliers (SiPM) represent an established solution for the light detection of large particle detectors. The NUV-HD-Cryo family from Fondazione Bruno Kessler exhibits a very attractive solution at liquid argon temperature, being stable with large overvoltages with a primary dark count rate below a few count per second per square centimeter. On the other hand, for those SiPMs the...

11. Measurement of SiPM external cross-talk in a liquid xenon detector

David Gallacher (McGill University)

9/22/22, 11:55 AM

Signal reconstruction and identification (analysis methods, simulations)

Presentation

Silicon photomultipliers (SiPMs) are the photo-detection technology of choice for future noble-liquid scintillator rare-event search experiments, both in neutrino-less double beta decay and dark matter. The high radio-purity and exceptional gain of SiPMs along with a high VUV detection efficiency make them ideal for these applications. The Light only Liquid Xenon (LoLX) experiment is a...

46. A large facility for photosensors test at cryogenic temperature

Dr Nicola Canci (Istituto Nazionale di Fisica Nucleare)

9/22/22, 12:10 PM

Light/charge readout (PMT, SiPM, WLS, electronics etc.)

Presentation

Silicon based photo-detectors are innovative light collecting devices and represent a successful technology in the field of direct dark matter search detectors based on liquified noble gases.
The DarkSide collaboration started a dedicated development and customization of SiPM technology for its specific needs resulting in the design, production and assembly of a large surface module of 20x20...

51. Rapid characterization of SiPMs for noble liquid experiments

Bindiya Chana (Carleton University)

9/22/22, 12:25 PM

Light/charge readout (PMT, SiPM, WLS, electronics etc.)

Presentation

Silicon photomultipliers (SiPMs) are emerging as the photodetector technology to be used in upcoming noble liquid experiments. Newly developed SiPMs sensitive to vacuum ultraviolet (VUV) light will be directly used for the readout of scintillation photons (λ = 175nm) from liquid xenon in future tonne-scale experiments such as nEXO searching for neutrinoless double beta decay in 136Xe. In this...

15. Novel VUV Light Detection in a Pixelated Liquid Argon Time Projection Chambers

Jonathan Asaadi (University of Texas at Arlington)

9/22/22, 12:40 PM

Light/charge readout (PMT, SiPM, WLS, electronics etc.)

Presentation

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...

27. Studies of event burst phenomenon with SiPMs at cryogenic temperature

Thomas Tsang (Brookhaven National Lab)

9/22/22, 12:55 PM

Light/charge readout (PMT, SiPM, WLS, electronics etc.)

Presentation

Silicon photomultipliers (SiPMs) are used to collect scintillation photons in many cryogenic noble liquid detectors deployed around the world, such as DarkSide, nEXO, MEGII, ProtoDUNE and DUNE. An event burst phenomenon was observed during routine characterization on many models of SiPMs operated in liquid nitrogen. These bursts of consecutive pulses are initiated by an intense dark...
