Experimental research on a boron-coated multi-wire proportional chamber neutron detector
2017
A boron-coated multi-wire proportional chamber (MWPC) neutron detector coupled with a delay line readout system has been investigated to possibly replace the 3He neutron detector. MWPC worked on the gas flow mode with Ar/ CO2 (90%/10%) and its readout system was based on the time-to-digital converter. The detection efficiency for a neutron wavelength of 0.247 nm was approximately 3.5%, and the spatial resolution was 5 mm. Other experimental results, such as gain and counting rate plateau, were also obtained.
