Description

Improving the durability and informativity of the recorded scattering patterns in neutron spectrometers is one of the key challenges. The use of a solid-state converter is not only a perspective alternative to ³He gas converters but also an essential measure for enhancing the performance and durability of thermal neutron detection systems. Resistive plate chambers are traditionally used in high energy physics as part of TOF systems due to their record high time resolution. This special feature enables the use of a delay line for high-precision coordinate determination.
The report will present the results of research on a manufactured thermal neutron detector based on a resistive plate chamber with a ¹⁰B₄C converter. The detector features a sensitive area of 150x75 mm and a delay line along its long side. The specific features of the detector's individual structural components and the manufacturing process will also be described. Measurements were performed using various laboratory radiation sources at different operating voltages to determine the parameters. The results to be presented and analyzed include the charge and PSD spectra, as well as the position and the sum of signal arrival times at both ends of the delay line relative to the anode. Based on the performed analysis, the operational mode of the produced detector will be justified.
