Abstract:
New method of neutron spectrum recovery described in the paper involves accelerated deuterons (that produce neutrons in DD
reaction) and allows getting neutron spectrum in any direction from computed time-velocity characteristics of deuterons. Time of flight signals registered in various distances and directions are used, that makes
information involved in the recovery process (Monte-Carlo simulation) more complete than in a one-directional case, although
additional assumption about axial symmetry of deuterons motion, is required. In the paper recent results of two standard tests
of the proposed method are presented demonstrating its capability to recover neutron spectrum from time-of-flight signals.
