Thermal Neutron capture cross section of palladium-107
Journal of Nuclear Science and Technology, 2007Co-Authors: Shoji Nakamura, Hideo Harada, Subramanian Raman, P. E. KoehlerAbstract:Prompt γ rays induced by Thermal Neutron capture on a 107Pd sample were analyzed to obtain the Thermal Neutron capture cross section for this nuclide. Intensities of prompt γ-ray transitions feeding the ground state were summed to determine a lower limit of 9:16 ± 0:27 b for the Thermal Neutron capture cross section. There have been no experimental values for this cross section. Our measured value is five times larger than evaluations of this cross section, which are based on resonance parameter data.

inorganic scintillators for Thermal Neutron detection
IEEE Transactions on Nuclear Science, 2012Co-Authors: C.w.e. Van EijkAbstract:The 3He shortage is forcing the Neutron community to look for other detection methods. The inorganic scintillator may be an alternative. Thermal-Neutron detection by means of inorganic scintillators has successfully been realized on a large scale at ISIS, UK, using 6LiF/ZnS:Ag mixed with an organic binder. This material is now introduced in the security field. For several reasons other traditional Neutron scintillators, 6Li-glass:Ce and 6LiI:Eu, and relatively new materials such as 6Li6 Gd(BO3 )3 :Ce and elpasolites like Cs2 LiYCl6 :Ce and Cs2 LiLaBr6 :Ce are hardly used or did not yet find their way to application. The same applies to more recently studied materials of the LICAF group. The pros and cons of these inorganic materials for Thermal Neutron detection will be discussed.

New Thermal Neutron Scintillators: and
2004Co-Authors: Aurélie Bessière, C.w.e. Van Eijk, Pieter Dorenbos, Karl KrämerAbstract:The Thermal Neutron detection properties of and single crystals are presented. The compounds show high scintillation photon yields of 70 000 and 88 200 photons emitted per absorbed Thermal Neutron, respectively. Events caused by primary electrons with energy below 2.9 and 3.4 MeV, respectively, can be separated from Neutron-induced events by pulse-height discrimination. For , due to the presence of a 4-ns fast core-va- lence luminescence, Thermal Neutrons and gamma rays can also be discrim- inated by means of the shape of the scintillation pulse. The main part of the scintillation pulse in is relatively slow, how- ever, has a relatively intense component with decay time.

Intense Thermal Neutron source based on MCF
Hyperfine Interactions, 1996Co-Authors: V. V. Kuzminov, Yu. V. Petrov, E. G. SakhnovskyAbstract:The conceptual scheme of an ecologically clean Thermal Neutron source (TNS) based on muon-catalyzed fusion (MCF) is proposed. The preliminary design shows that an MCF-based TNS can produce the maximum value of unperturbed Thermal Neutron flux 1015 n/cm2 s using for muon production a beam power of about 14 MW supplied by an accelerator of the next generation.

MC simulation of beam parameter effects on Thermal Neutron imaging quality
Nuclear Techniques, 2010Co-Authors: Liu BinAbstract:The main influence factors of Thermal Neutron radiography include collimation ratio, cadmium ratio, scattering Neutron, spatial distribution of Neutron flux and so on. In this paper, the influence factors on Thermal Neutron imaging quality are analyzed by Monte Carlo simulation, and relevant measures are proposed for quality improvement of the Thermal Neutron imaging technique.

Effect on material properties by Thermal Neutron radiography
Nuclear Electronics and Detection Technology, 2008Co-Authors: Liu BinAbstract:Thermal Neutron radiography is a useful complementarity for X-ray and other nondestructive testing technique.As the different interaction mechanism with material from X-ray,Neutrons are thought to affect the material properties during the course of testing.The effect of Thermal Neutron radiography on material is deduced theoretically according to the basic principium of interaction with material,and the result indicates that the effects is negligible and the users are thought that the result is reasonable.

The Primary Experimental Study of Thermal Neutron Tomography in SPRR-300
Computerized Tomography Theory and Applications, 2007Co-Authors: Liu BinAbstract:Thermal Neutron radiography is a useful complementary tool of the other non-destructive testing methods for the hydrogenous materials and heavy metal subassembly,and Thermal Neutron tomography has not been developed in China.By the use of the CCD-based Thermal Neutron digital radiography facility in SPRR-300 reactor and the Al column sample with holes,the projecting data of 36 multiplied 552 groups are collected.After and before the data are processed,the tomography image is gotten by the filter anti-projection,and the tomography image reveals the basic structure of the sample and it approves that it is feasible that Thermal Neutron tomography is developed by the uses of the Thermal Neutron radiography facility in No.300 reactor and it is ready for future work.

CaSO4:Dy microphosphor for Thermal Neutron dosimetry
Journal of Luminescence, 2016Co-Authors: Mahesh S. Bhadane, Nandkumar T. Mandlik, B.j. Patil, S.s. Dahiwale, K.r. Sature, Vasant N. Bhoraskar, Sanjay D. DholeAbstract:Abstract Dysprosium-doped calcium sulphate (CaSO 4 :Dy) microphosphor was synthesized by acid re-crystallization method and its thermoluminescence (TL) properties irradiated with Thermal Neutrons was studied. Structural and morphological characteristics have been studied using X-ray diffraction and SEM which mainly exhibits a orthorhombic structure with particle size of 200 to 250 µm. Moreover, Thermal Neutron dosimetric characteristics of the microphosphor such as thermoluminescence glow curve, TL dose–response have been studied. This microphosphor powder represents a TL glow peak ( T max ) centered at around 240 °C. The TL response of CaSO 4 :Dy microphosphor as a function of Thermal Neutron fluence is observed to be very linear upto the fluence of 52×10 11 n/cm 2 and further saturates. In addition, TL glow curves were deconvoluted by computerized glow curve deconvolution (CGCD) method and corresponding trapping parameters have been determined. It has been found that for every deconvoluted peak there is change in the order of kinetics. Overall, the experimental results show that the CaSO 4 :Dy microphosphor can have potential to be an effective Thermal Neutron dosimetry.
