Condition Based MaintenanceX-band LinacX-ray
概要
We are developing X-ray nondestructive testing (NDT) system using with portable X-band linac. This system uses 2.4 GHz X-band linac and 250 kW magnetron. Our system energy is 950 keV for Japanese regulation. Th erefore we can use it on-site using local radiation protection. We measured electron beam and X-ray. We have started X-ray maging test. We will use this system for condition based maintenance of pump-impeller a t nuclear plants. The linac based X-ray source can generate pulsed X-ray. Therefore we can get still images without stopping rotation when E-ray repetition rate synchronizes impeller's rotation rate. We are suc cessful in proof of principle using a simple fan end a synchronized circuit. We prepare real-time imaging for conventional pump. In this paper, we will explain the letail of this system and experimental results.
