Neutron Imaging Study at Peking University

GUO Zhiyu (Peking University)

Neutron imaging techniques were investigated at Peking University based on a 4.5 MV Van de Graaff accelerator. The thermal neutron radiography, fast neutron radiography and fast neutron resonance radiography were tested. A new accelerator based neutron source with a yield of 1012 n/s is being set up, which consists of a 2 MeV deuteron RFQ accelerator, a beryllium target, a moderator-collimator-shielding assembly and a CCD neutron imaging system. Under the collaboration with the China Institute of Atomic Energy, a neutron imaging line has been designed and is going to be constructed at the China Advanced Research Reactor.
