Abstract: The neutronic performance of a coupled grooved moderator of liquid-hydrogen was experimentally studied and from the measured neutronic performance it was proved that this type of grooved moderator is useful not only for short pulse spallation sources but also for long pulse spallation sources.

Keywords: grooved moderator, coupled moderator, liquid-hydrogen, pulsed neutron performance, long pulse spallation source
