Achievements of on-site inspection of social and industrial infrastructures by 950 keV/3.95 MeV X-band linac X-ray source. First on-site use of /3.95 MeV and dynamic inner inspection by 950 keV

Soundness diagnosis of society and the industrial infrastructure is indispensable to realize safe reliable society for regular service. It goes an investigation by the viewing, non-destructive inspection using X-rays. In the current technique, the accurate check technology by the non-destructiveness is not established. It has a problem for example, too long inspection time, to get an indistinct image in the case of a material with the thickness. The development of the technique to diagnose a non-destructive inspection and soundness technology is necessary for maintenance and management such as a bridge, a concrete structure, an industrial plant. We promote an examination for seeing through structure soundness of various society, industry infrastructure and carry X-band linac X-ray source into the on-site. We carried out a removal material and an on-site proof examination to be able to introduce variety of use environments. (author)
