The Darkside-20k Data Acquisition System
Fabio Acerbi, Pushparaj Adhikari, Paolo Agnes +289
DarkSide-20k is a WIMP search experiment using liquid argon as a target, designed to perform a background-free search for dark matter with unprecedented sensitivity, and is current…
Sensitivity projections for a dual-phase argon TPC optimized for light dark matter searches through the ionization channel
P. Agnes, I. Ahmad, S. Albergo +296
Dark matter lighter than 10 GeV/c encompasses a promising range of candidates. A conceptual design for a new detector, DarkSide-LowMass, is presented, based on the DarkSide-50…
Calibration of the liquid argon ionization response to low energy electronic and nuclear recoils with DarkSide-50
The DarkSide collaboration, P. Agnes, I. F. M. Albuquerque +136
DarkSide-50 has demonstrated the high potential of dual-phase liquid argon time projection chambers in exploring interactions of WIMPs in the GeV/c mass range. The technique, b…
A study of events with photoelectric emission in the DarkSide-50 liquid argon Time Projection Chamber
50 Collaboration, P. Agnes, I. F. M. Albuquerque +135
Finding unequivocal evidence of dark matter interactions in a particle detector is a major objective of physics research. Liquid argon time projection chambers offer a path to prob…
Performance of the ReD TPC, a novel double-phase LAr detector with Silicon Photomultiplier Readout
P. Agnes, S. Albergo, I. Albuquerque +64
A double-phase argon Time Projection Chamber (TPC), with an active mass of 185 g, has been designed and constructed for the Recoil Directionality (ReD) experiment. The aim of the R…
Separating Ar from Ar by cryogenic distillation with Aria for dark matter searches
DarkSide Collaboration, P. Agnes, S. Albergo +309
The Aria project consists of a plant, hosting a 350 m cryogenic isotopic distillation column, the tallest ever built, which is currently in the installation phase in a mine shaft a…
SiPM-matrix readout of two-phase argon detectors using electroluminescence in the visible and near infrared range
The DarkSide collaboration, C. E. Aalseth, S. Abdelhakim +312
Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter searches to record (in the gas phase) the ionization signal induced by particle…
Electroluminescence pulse shape and electron diffusion in liquid argon measured in a dual-phase TPC
P. Agnes, I. F. M. Albuquerque, T. Alexander +163
We report the measurement of the longitudinal diffusion constant in liquid argon with the DarkSide-50 dual-phase time projection chamber. The measurement is performed at drift elec…
DarkSide-20k: A 20 Tonne Two-Phase LAr TPC for Direct Dark Matter Detection at LNGS
C. E. Aalseth, F. Acerbi, P. Agnes +282
Building on the successful experience in operating the DarkSide-50 detector, the DarkSide Collaboration is going to construct DarkSide-20k, a direct WIMP search detector using a tw…
Cryogenic Characterization of FBK RGB-HD SiPMs
C. E. Aalseth, F. Acerbi, P. Agnes +268
We report on the cryogenic characterization of Red Green Blue - High Density (RGB-HD) SiPMs developed at Fondazione Bruno Kessler (FBK) as part of the DarkSide program of dark matt…
Imaging with the invisible light
R. Bellazzini, G. Spandre, A. Brez +12
We describe a UV photo-detector with single photon(electron) counting and imaging capability. It is based on a CsI photocathode, a GEM charge multiplier and a self triggering CMOS…
Studies of 100 um-thick silicon strip detector with analog VLSI readout
T. Hotta, M. Fujiwara, T. Kinashi +6
We evaluate the performances of a 100 um-thick silicon strip detector (SSD) with a 300 MeV proton beam and a 90Sr beta-ray source. Signals from the SSD have been read out using a V…
