abstract = {Small-angle neutron scattering (SANS) experiments have
become one of the most important techniques in the
investigation of the properties of material on the atomic
scale. Until 2001, nearly exclusively 3He-based detectors
were used for neutron detection in these experiments, but
due to the scarcity of 3He and its steeply rising price,
researchers started to look for suitable alternatives.
Scintillation based solid state detectors appeared as a
prominent alternative. Silicon photomultipliers (SiPM),
having single photon resolution, lower bias voltages
compared to photomultiplier tubes (PMT), insensitivity to
magnetic fields, low cost, possibility of modular design and
higher readout rates, have the potential of becoming a
photon detector of choice in scintillator based neutron
detectors. The major concerns for utilizing the SiPM
technology in this kind of applications are the increase in
their noise performance and the decrease in their photon
detection efficiency (PDE) due to direct exposure to
neutrons. Here, a detailed comparative analysis of the PDE
performance in the range between UV and NIR parts of the
spectra for three different SiPM technologies, before and
after irradiation with cold neutrons, has been carried out.
For this investigation, one digital and two analog SiPM
arrays were irradiated with 5Å wavelength cold neutrons and
up to a dose of 6×1012 n/cm2 at the KWS-1 instrument of the
Heinz Maier-Leibnitz Zentrum (MLZ) in Garching, Germany.},
