First Claim
Patent Images
1. A neutron source comprising:
- an ion source;
a target;
a secondary election shield disposed about said target, said secondary electron shield including an ion entrance aperture disposed to have ions emitted from said ion source impact said target;
a first stage moderator disposed adjacent said secondary electron shield; and
,a second stage moderator disposed about said first stage moderator.

Abstract
A novel method and compact neutron source for generating thermal neutrons is described that uses an ion source to emit ions toward a target where neutrons are generated. Surrounding the target is a secondary electron shield, and surrounding the target is a first stage moderator to reduce the energy of generated fast neutrons. Enclosing the first stage moderator is a second stage moderator with a thermal neutron port.

14. A method of production of neutrons comprising:
-
directing ions emitted from an ion source to impact a target where neutrons are produced; capturing secondary electrons at a secondary electron shield disposed about said target; passing generated neutrons through a first stage moderator disposed about said secondary electron shield or target to provide first moderated neutrons; and passing the first moderated neutrons thorough a second stage moderator disposed about said first stage moderator. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 27, 28, 29)
