Displacement damage induced by neutron irradiation in China Spallation Neutron Source(CSNS) is studied on bipolar transistors with lateral PNP, substrate PNP, and vertical NPN configurations, respectively. Comparison ...
Organ coefficient is the ratio of animal organs to body weight,which is relatively constant under normal conditions.After immune function of animal is damaged,the organ weight may be changed,which leads to the change ...
The favourable physical properties of SiC make it a potential material for use as containment layer in new generation nuclear reactors.The material will thus be exposed to high temperatures and fluences from fission p...
CN-85 detector which covered with boric acid H3Bo3 pellete has been irradiated by thermal neutrons from (241Am-9Be) source with activity 12 Ci and neutron flux 105 n. cm-2. s-1. The irradiation times-TD for detector w...
Gamma-ray total absorption facility(GTAF)is composed of 40pieces of BaF2detector.According to the requirements of the experiment,the amplitude of each detector output signal must be consistent,therefore,independent vo...

The difference of annealing behaviors of vacancy-oxygen complex (VO) in varied dose neutron irradiated Czochralski silicon: (S1 5×1017 n/cm3 and S2 1.07×1019 n/cm3) were studied. The results show that the VO is one ...
MgO single crystal was irradiated by neutron up to a dose of 5.74×1018 cm-2. The radiation damage and its recovery were studied by means of UV-VIS and EM spectroscopy. The results indicate that the irradiation genera...
