Nanoseconds Timing System Based on IEEE 1588 FPGA Implementation
D. Pedretti, M. Bellato, R. Isocrate +54
Clock synchronization procedures are mandatory in most physical experiments where event fragments are readout by spatially dislocated sensors and must be glued together to reconstr…
DarkSide-50 532-day Dark Matter Search with Low-Radioactivity Argon
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +172
The DarkSide-50 direct-detection dark matter experiment is a dual-phase argon time projection chamber operating at Laboratori Nazionali del Gran Sasso. This paper reports on the bl…
Constraints on Sub-GeV Dark Matter-Electron Scattering from the DarkSide-50 Experiment
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +193
We present new constraints on sub-GeV dark matter particles scattering off electrons in argon based on an analysis of ionization signal data from the DarkSide-50 detector.
Low-Mass Dark Matter Search with the DarkSide-50 Experiment
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +192
We present the results of a search for dark matter WIMPs in the mass range below 20 GeV/c^2 using a target of low-radioactivity argon. The data were obtained using the DarkSide-50…
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…
Charge reconstruction in large-area photomultipliers
M. Grassi, M. Montuschi, M. Baldoncini +60
Large-area PhotoMultiplier Tubes (PMT) allow to efficiently instrument Liquid Scintillator (LS) neutrino detectors, where large target masses are pivotal to compensate for neutrino…
