An accelerator-type neutron source and a method of controlling the same |
(57) An accelerator-type neutron source employs a target, an ionization section and a
replenisher for supplying accelerator gas. A positive voltage pulse is applied to
the ionization section to produce a burst of neutrons. A negative voltage pulse is
applied to the ionization section upon the termination of the positive voltage pulse
to effect a sharp cut-off to the burst of neutrons.
