Description

technical field [0001] The invention relates to a standing wave resonance aging device and method for a high-power input coupler, belonging to the field of accelerators. Background technique [0002] In the field of accelerators, coaxial high power input couplers are commonly used to provide energy from an RF power source to an RF accelerating cavity. Before the high-power input coupler is formally installed in the RF cavity, it needs to be experienced offline to improve the actual operation stability. The common offline aging methods of couplers are traveling wave aging and standing wave aging. In order to reduce the power required by the offline aging method, a traveling wave resonant ring device is usually used, but the structure of the device is complex and the power gain is low. The gain is generally only It is about 20 times. In recent years, researchers at Fermilab in the United States have proposed a standing wave partial resonance device, which contains a total re...

The common offline aging methods of couplers are traveling wave aging and standing wave aging. In order to reduce the power required by the offline aging method, a traveling wave resonant ring device is usually used, but the structure of the device is complex and the power gain is low. The gain is generally only about 20 times

In recent years, researchers at Fermilab in the United States have proposed a standing wave partial resonance device, which contains a total reflection movable short-circuit plate and a partial reflection movable reflector, so it cannot form a complete standing wave resonance, and the power gain is only 3 to 4 times
