| 1 | The review and prospect of neutron radiography in China显示文摘Neutron radiography is one of radiography non-destructive testing.It is a valuable complementary of X and γ rays radiography.The present status and history of neutron radiography in China was described briefly,facilities of neutron radiography and their development were introduced in this paper. | Tang Bin Mo Dawei Huo Heyong Wu Yang Liu Bin Sun Yong | 2009 | Engineering Sciences2009，7，4： | 0 |
| 2 | The latest progress of thermal neutron tomography at SPRR-300 reactor显示文摘Thermal neutron radiography is a useful complementary tool of the other non-destructive testing methods for the hydrogenous materials and heavy metal subassembly.By the use of MC method program and the thermal neutron digital radiography facility at SPRR-300 reactor,the simulation and experimental study of the thermal neutron tomography has been developed.Its method and result has been introduced and analyzed. | Tang Bin Huo Heyong Liu Bin Sun Yong Wu Yang | 2009 | Engineering Sciences2009，7，4： | 0 |
| 3 | The pilot experimental study of 14 MeV fast neutron digital radiography显示文摘14 MeV Fast neutrons has good penetrability and the 14 MeV fast neutron radiography can meet the need of Non-Destructive Test of the structure and lacuna of heavy-massive sample, whose shell is made of heavy metal and in which there are some hydrogen materials, and the study of fast neutron digital radiography just begins in China. By the use of a D-T accelerator, a digital imaging system made up of a fast neutron scintillation screen made of ZnS(Ag) and polypropylene, lens and a scientific grade CCD, the experimental study of fast neutron radiography has been done between 4.3×1010-6.8×1010 n/s of neutron yield. Some 14 MeV fast neutron digital radiographs have been gotten. According to experimental radiographs and their data, the performance of the fast neutron scintillation screen and the basic characters of 14 MeV fast neutron radiography are analyzed, and it is helpful for the further research. | TANG Bin ZHOU ChangGen HUO HeYong WU Yang LIU Bin LOU BenChao SUN Yong | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，9： | 0 |
