I don't think that the fusor should produce any thermal neutrons. They should all be fast with very few happening to fall into the slow category. You need to thermalize the neutrons, as I understand it. Try completely surrounding the He-3 tube with a thick, polyethylene cylinder (2-3 inch thick) or an equivalent in paraffin, water, etc. and see if the count improves dramatically.
