The Thermal Neutron Monitor with the *1*0B&sub(4)C Converter for the Spin-Echo SEM Spectrometer / D.S.Ilyin, A.G.Kolesnikov, [a.o.]. – Text : electronic // Nuclear Instruments & Methods in Physics Research A. – 2025. – Vol. 1080. – P. 170738. – URL: https://doi.org/10.1016/j.nima.2025.170738. – Bibliogr.: 37.

A prototype of thermal neutron beam monitor based on a multiwire proportional chamber design with a thin-film converter B&sub(4)C has been developed and constructed. The prototype was tested on the &sup(252)Cf neutron source, characteristic amplitude spectra were obtained. The possibility of a reliable rejection of unwanted low-amplitude events was demonstrated using the &sup(90)Sr *b-source. Based on the prototype, two identical neutron beam monitors with the required parameters for the SEM neutron resonance spin-echo spectrometer were manufactured. This instrument is now under construction and will be part of the instrument suite of the high-flux reactor PIK in Gatchina, Russia.
