Description

Optimization studies on a coupled liquid-hydrogen moderator system were performed experimentally and the results were compared with those of decoupled liquid-hydrogen and solid-methane moderators. A very large gain factor is obtained in the cold neutron region. Pulse characteristics were also studied and it was found that the pulse broadening by coupling is rather modest. (orig.)
