Abstract :
We are developing a compact X-ray source for nondestructive testing (NDT) system. We aim to develop a portable X-ray NDT system by 950 keV X-band linac to realize on-site inspection. We use a low power (250 kW) magnetron as RF source for compactness of whole system. By using low power magnetron, we can use small magnetron power supply and cooling system. Additionally, the system has X-band linac and it has small spot size of electron beam. Our final goal of X-ray spot size is less than lmm. We have designed the linac structure of the pi mode at low energy parts and the pi/2 mode at high energy parts by using calculation codes. It was finished to measure resonant frequency and electromagnetic field of the linac. And the result of measurement consists with calculation data. The components of this system was completed and installed in the Nuclear Professional School, the University of Tokyo. We are carrying out electron beam accelerate testing.
