Condition Based Maintenance Magnetron X-band Linac X-ray
We are developing portable non-destructive testing (NDT) X-ray source with X-band linac and low power magnetron. Now, we start the experiment of electron acceleration and X-ray generation using by 950 keV X-band linac NDT system. The 950 keV X-band linac X-ray generator is under development for corrosion wastage of tubes and condition bas ed maintenance of impeller pumps. However, about 1 MeV X-ray source can be only used for thin tubes of about 20 mm thickness. Therefore, we start to design about 4 MeV X-...

CT Linacs NDE X-ray
Abstract: Since more and more bridges built several decades ago in Japan have become aged and dangerous, the non-destructive evaluation of those bridges is really an urgent problem. CT system with portable 3.95MeV linacs for bridge inspection is considered to work on-site, considering the law of Japanese radiation protection allows using linacs up to 4MeV outside radiation controlled area. The system would confirm the internal steel si tuation of bridges and analyze structural strain and stress with 3D mod...

Dual-energy CT NDE Scattered X-ray noise Structural analysis X-band linac
In situ CT application for NDE of degradation bridges is under development, with portable 950keV/3.95 MeV X-band linac as x-ray source. Collimator is adopted to reduce scattered X-ray noise. Material analysis and erosion estimation through dl-energy CT method is integrated in order to inspect the erosion situation of i nner steel rod. Reconstruction technique with incomplete projection data is studd considering limitation of projection angle range during onsite scanning. Furt hermore, based on 3D model bui...
