Pennsylvania State University proposes to acquire an Adelphi dual-tube 14-MeV Deuterium-Tritium (D-T) neutron-generation system. One tube has a neutron output of 108 n/sec, and the other tube has a neutron output of 1010 n/sec. the lower-neutron-output part of the system will provide a capability to accurately detect the alpha particles resulting from the D-T fusion reaction, thereby allowing for accurate measurements of neutron emission angles. A small ion beam spot size on the target is paramount for measuring precise origin of neutrons and alphas.
