When a C₈D₈ pitcher was irradiated by a pulsed laser, deuterons were generated and accelerated. The accelerated deuterons were injected into the Be catcher, and fast neutrons were produced. The fast neutrons were slowed down by a moderator and transmitted through a pair of thin sheets of indium and silver samples, which acted as mock nuclear materials. The transmitted neutrons were detected by a neutron detector installed at flight distance of 3.6 m.
