The paper introduces R&D of industrial E-LINAC in China Institute of Atomic Energy (CIAE) , including electron gun, modulator, accelerating tube, assembling and testing. Based on these R&D results, the GT series for non-destructive testing(NDT) and FZ series for irradiation processing are developed successfully. At present these E-LINACs play important roles in pressure vessel inspection, food preservation, sterilization and material modification, promoting the E-LINACs application as well as economic development in China.
