Characterization of the large-size NDL EQR20 silicon photomultipliers
Yu. A. Melikyan, I. G. Bearden, V. Buchakchiev +3
Unlike most commercially available silicon photomultipliers (SiPMs), EQR20 SiPMs produced by the Novel Device Laboratory (NDL) avoid using individual resistors to quench the avalan…
Status and performance of the ALICE Fast Interaction Trigger
Yury Melikyan
The ALICE apparatus at CERN has undergone significant upgrade during the LHC's Long Shutdown 2 to increase the experiment's rate capability and measurement precision for Run 3 and…
Performance of the electromagnetic and hadronic prototype segments of the ALICE Forward Calorimeter
M. Aehle, J. Alme, C. Arata +74
We present the performance of a full-length prototype of the ALICE Forward Calorimeter (FoCal). The detector is composed of a silicon-tungsten electromagnetic sampling calorimeter…
Characteristic properties of Planacon MCP-PMTs
Yu. A. Melikyan, M. Slupecki, I. G. Bearden +14
A systematic investigation of Planacon MCP-PMTs was performed using 64 XP85002/FIT-Q photosensors. These devices are equipped with microchannel plates of reduced resistance. Result…
Measurement of scintillation response of CsI[Na] to low-energy nuclear recoils by COHERENT
D. Akimov, P. An, C. Awe +74
We present results of several measurements of CsI[Na] scintillation response to 3-60 keV energy nuclear recoils performed by the COHERENT collaboration using tagged neutron elastic…
Anode current saturation of ALD-coated Planacon MCP-PMTs
E. V. Antamanova, I. G. Bearden, E. J. Garcia-Solis +8
We have measured and compared the characteristics of ALD-coated Planacon MCP-PMTs (XP85112/A1-Q-L) with their non-ALD counterparts (XP85012/A1-Q). While the later show excellent pe…
COHERENT 2018 at the Spallation Neutron Source
D. Akimov, J. B. Albert, P. An +76
The primary goal of the COHERENT collaboration is to measure and study coherent elastic neutrino-nucleus scattering (CEvNS) using the high-power, few-tens-of-MeV, pulsed source of…
The COHERENT Experiment at the Spallation Neutron Source
COHERENT Collaboration, D. Akimov, P. An +64
The COHERENT collaboration's primary objective is to measure coherent elastic neutrino-nucleus scattering (CEvNS) using the unique, high-quality source of tens-of-MeV neutrinos pro…
Observation of light emission from Hamamatsu R11410-20 photomultiplier tubes
D. Yu. Akimov, A. I. Bolozdynya, Yu. V. Efremenko +4
We have shown that high voltage biased Hamamatsu R11410-20 photomultipliers with a dark count rate above 10 kHz emit single photons. The effect has been observed in a few units at…
Experimental study of ionization yield of liquid xenon for electron recoils in the energy range 2.8 - 80 keV
D. Yu. Akimov, V. V. Afanasyev, I. S. Alexandrov +23
We present the results of the first experimental study of ionization yield of electron recoils with energies below 100 keV produced in liquid xenon by the isotopes: 37Ar, 83mKr, 24…
