Abstract :
In recent years, three types of linacs have been developed for large container inspection for customs applications, viz., S-Band 9 MeV travelling-wave (TW) linacs, S-Band 6 MeV Standing-wave (SW) linacs and X-Band 2.5 MeV (SW) linacs. In cooperation with Tsinghua Tongfang Co. Ltd, a series of container inspection systems has been produced. Seven sets of large container inspection systems with 9 MeV TW linacs have been installed at Tianjin, Dalian, Qingdao, Shanghai, Dapeng, and Nanjing Seaport customs. These systems are called "the fixed type". Based on our development of a compact X-band 9300 MHz 2.5 MeV SW linac, a novel "mobile type" large container inspection system was completed. Four sets of these systems have been installed in four customs areas. Another container inspection system with a S-Band 6MeV SW linac, installed in a simple shielding shed with cement blocks, is called "the combined type". Four sets of these systems have been equipped in four customs areas
