“…Recently, some researchers have employed them in neutron detection applications [30,31]. Most are small-area neutron position-sensitive detectors [32][33][34] or neutron counters [35][36][37]. Our aim is to apply a SiPM device in a large-area scintillator neutron detector in a neutron spectrometer.…”

The China Spallation Neutron Source (CSNS) is a large scientific facility whose main aim is to support multidisciplinary research on material characterization using neutron scattering. Twenty neutron spectrometers will be built as multidisciplinary platforms for scientific research by national institutions, universities, and industry. Scintillator neutron detectors for the spectrometers under construction have recently been developed using silicon photomultipliers (SiPMs) for the readout. This paper studies the characteristics of three candidate SiPMs, including the breakdown voltage, gain, temperature coefficient, dark count rate, and radiation tolerance. Two measurement platforms were built to evaluate each SiPM. We summarize the results from our analysis of laboratory tests and beam test data to characterize the performance of the SiPMs. The MicroFJ-30035-TSV SiPM manufactured by the SensL Corporation is chosen as the best SiPM for the scintillator detectors at CSNS.

In recent years, the price increase of 3 He has triggered the search for alternative neutron detectors. One of the viable options is a scintillation-based neutron detector. Usually, photomultiplier tubes (PMTs) are used in these detectors for photodetection. However, the increase in performance requirements such as the operability in magnetic field and spatial resolution necessitates an advanced neutron detector. Therefore, we developed a detector prototype with an active area of 13 cm × 13 cm using silicon photomultipliers (SiPMs). As compared to PMTs, SiPMs offer more compactness, more robustness, and a lower sensitivity to magnetic field. The final detector is aimed to be used in the future at the TREFF instrument of the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching, Germany, for neutron reflectometry (NR). First measurements were carried out at TREFF and at the dedicated detector test instrument V17 at BER-II of HZB in Berlin, Germany. In this study, we report the results for detection efficiency, gamma discrimination, 2-D position resolution, count rate, and detection linearity.

“…According to the manufacturer, this thickness results in 73% interaction probability for 2.5 Å neutrons. Capture of a neutron by a lithium-6 nucleus results in the nuclear reaction The reaction products deposit their energy within short (<150 µm [7]) distance from the capture position resulting in emission of about 6200 photons with the emission peak at 395 nm.…”

We present characterization results of a neutron Anger camera based on a lithium-6 loaded cerium activated silicate glass scintillator (33.3 x 33.3 x 1 mm 3 ) and an array of 64 silicon photomultipliers. Reconstruction of the scintillation events is performed with a statistical method, implemented on a graphics processing unit (GPU). We demonstrate that the light response model of the detector can be obtained from flood irradiation calibration data using an unsupervised iterative procedure. The useful field of view is 28 x 28 mm 2 . The spatial resolution measured at 2.5 Å neutron beam is better than 0.6 mm FWHM and the energy resolution at the neutron peak is 11%.
