Model of Radon Volume Radioactivity and Verification

Hedianzixue yu tance jishu (2009)

Bin Tang

Standard radon chamber,the third age of standard radon sources,supplements radon automatically according to the value of expectation by intelligentized control technology,which can keep stable radon volume radioactivity in a long time.In this paper model of radon supplementation and model of radon stabilization of radon volume radioactivity are explored,and measurement technologies of correlation parameters are established.Through the experiments of radon volume radioactivity,the standard radon chamber established by this model is proved much productive.

An empirical formula for scattered neutron components in fast neutron radiography

Chinese Physics C (2011)

Dou Haifeng Bin Tang

Scattering neutrons are one of the key factors that may affect the images of fast neutron radiography. In this paper, a mathematical model for scattered neutrons is developed on a cylinder sample, and an empirical formula for scattered neutrons is obtained. According to the results given by Monte Carlo methods, the parameters in the empirical formula are obtained with curve fitting, which confirms the logicality of the empirical formula. The curve-fitted parameters of common materials such as 6LiD are given.

Propagation Properties of Hermite-Cosh-Gaussian Beams in Uniaxially Anisotropic Crystals

Journal of Optoelectronics·laser (2006)

Bin Tang Tang Huiqin

The propagation properties of polarized Hermite-Cosh-Gaussian(HChG) beams along the optical axis of uniaxially anisotropic crystals are investigated.Based on the paraxial vectorial theories of beam propagation,an analytic expression of the diffraction light field is obtained.The effects of the anisotropy on the polarization properties of the diffracted HChG light beams have also been explained by means of the numerical method.The results elucidate that the distributions of the optical field change with the different parametric variation for the polarized beams in the anisotropic crystals.

Global dynamic routing for scale-free networks with heterogeneous node capacity

Zou Yamei Bin Tang

In this paper, we propose a new global dynamic routing strategy on scale-free networks with heterogeneous node capacity. The new routing strategy for network systems not only takes the information of the queue length of nodes into account, but also considers node's delivering capacity. Under the new routing strategy, the system can reach a very high network capacity, which is four times more than that of the efficient routing strategy. The time delay of updating node queue lengths is also investigated to verify the robustness of the strategy. And it is found that with the increment of time delay, the system capacity remains constant, but the travel time for packets slightly increases.

Thermal Neutron Digital Imaging System Based Cooled CCD

Computerized Tomography Theory and Applications (2004)

Bin Tang

The imaging system is one of key assembles of neutron radiography facility. The collimator neutron flux is drawn from the horizontal channel by the use of SPRR-300 as a neutron resource. The convector made of 6LiFZnS(Ag) and the long focus professional twilight lens with the small field of view are used, and the digitalized CCD(Charge Coupled Device) camera is developed by the use of scientific grade CCD chip, the double thermocouple refrigeration and 14bit A/D convector. The image grabbing, processing and analyzing software of double bytes has been developed by the use of Visual C++ and C++ Builder, and the facility of anti-radiation for CCD is set up. The experiments show that the used technology is reasonable, and the destination of design is arrived at and the image quality can be matched with similar device at abroad.
