Electroluminescent Chamber for Study of Subbarrier Fission of Transuranium Elements
An electroluminescent fission chamber based on optical detection of fission pulses is described. The use of the optical path can significantly reduce statistical measurement errors, gamma background and increase the resistance to electrical and mechanical interference. Electroluminescence in strong electric fields with a significant, 103–104 times, increasing in light intensity makes it possible to record individual fission events in a counting mode. These advantages will allow high-resolution measurement of the energy dependence of the sub-barrier fission cross sections of transuranium elements on lead slowing down neutron spectrometers.
