A neutron detector with WLS-fibers readout and SiPM

Primary authors



A new neutron position sensitive detector was developed and tested. For neutron detection we uses LiF/ZnS-scintillation sheet. For light readout wavelength shifting (WLS) fibers used. Each end of these fibers connected with SiPM. The coordinate resolution of this detector is about 1 mm. Each scintillation sheets have efficiency 25 % for thermal neutrons. The detector can consist 2-3 sheets for more efficiency. A neutron coordinate determined by the position of the SiPM with pulse. The events was registered by gate pulses which generate by PMT mounted behind the scintillator sheets. This detector cam be useful for Small angle neutron spectrometers at continuous and at pulsed neutron sources.
