概要
Our portable X-band (9.3GHz) 950KeV linac has been successfully upgraded. The problems of RF power oscillation , beam current oscillation and reduction and finally lack of X-ray intensity were solved by replacing the axia l coupling cavities with the side-coupled ones. Designed X-ray dose rate of 0.05 Sv/min@lm is going to be achi eved. Length of the accelerating tube is reduced to less than 25 cm. X-ray source part with the local radiation shielding is connected by the flexible waveguide with the box of the 210 kW magnetron and cooling unit. The tot al system consists of the three suit-case-size units, the last of which is one for the electric power supply. E ven on-line dynamic transmission imaging is available by using the high intensity X-ray camera. Demonstration of the measurement of wall thinning of metal pipes with thick thermal shielding has been successfully finished.
