TI - Development of Un-destructive Inspection System for Large Concrete Infrastructure by using Accelerator Based Compact Neutron Source J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Aged large concrete structure, such as highway, bridges and so on, need to be inspected in order to maintain with less cost by un-destructive method. We have been developing un-destructive inspection system by using fast neutron which can penetrate thick concrete. The system will be consisted of (1) Transportable Accelerator based Neutron Source, (2) Fast neutron imaging detector, and (3) Image processing for getting 3D image. RIKEN Accelerator based compact Neutron Source (RANS), which consists of 7MeV proton LINAC and target station, has been operating since 2013. RANS can generate thermal (~25meV) and fast (~2MeV) neutron. Fast neutron detector are developed with plastic scintillator and semiconductor photon sensors. It can see 10mm thick steel rod with 2mm accuracy through 300mm thick concrete.
