Abstract :
We have preliminarily investigated the performance of the optical capillary gas proportional counter (CGPC) to obtain the absorption point of cold neutron at JRR-3 in JAERI. The CGPC with a gas mixture of 3He+8%CH4+2%TMA at 1.1 atm was operated at the gas gain of up to 10 000. A track image produced from a nuclear reaction between a cold neutron and 3He was a straight line. For the track image, the triton and the proton were identified. The identification indicates that the neutron absorption point can precisely determine from the track image.
