| 摘要 | PURPOSE: To make energy variable while reducing power leakage by a method in which when detuning the prescribed combination cabities of a standing wave acceleration tube, said combination cavities are formed while being provided with a detuning rod, which makes said combination cavities to contact with the cylindrical surface on the opposite side while crossing the post part. CONSTITUTION: A side cavity combination type standing wave acceleration tube is formed including a beam pass hole 6, a microwave power supply waveguide 5, acceleration cavities A 1 WA 30 , combination cavities S 1 WS 29 , a gap G for forming an electric field etc. And, when making the microwave power not to be propagated to the acceleration cavities A 16 WA 30 in the rear by detuning the combination cavity S 15 , the combination cavity S 15 is so constituted that a detuning rod 11 may be made to pass the post part 10 and to be inserted into and brought in contact with the hole 13 provided on the cylindrical surface 9 on the opposite while forming the contact end part 12 as a metal different from the metal forming the cylindrical surface 9. Accordingly, when energy is made variable, a low energy beam can be effectively obtained due to reduced leakage power. COPYRIGHT: (C)1985,JPO&Japio |
