Embodiment 1

[0030] Adopt the tuning system of the present invention to carry out microwave parameter tuning to a certain radio frequency accelerating tube (referring to appendix Figure 1-3 ), the main steps are as follows:

[0031] (1) Determine the cavity to be tuned and the tuning amount, such as the No. 25 cavity in this embodiment, the tuning amount is ﹢800kHz;

[0032] (2) Slide the tuning device mobile module along the first slide rail 4 to the position of the cavity to be tuned;

[0033] (3) Tuning the cavity through tuning equipment.

[0034] The tuning equipment of step (3) can also be attached Figure 4 The operation of the tuning process of the tuning device 6 shown is as follows: Screw the tuning screw 7 into the tuning hole of the cavity and tighten it; tune the cavity by turning the tuning knob 8, and stop when the tuning amount reaches +800kHz. Remove the cavity to complete the tuning.

[0035] Practical applications show that the above tuning process is more convenien...

Embodiment 2

[0037] Adopt probe measurement system of the present invention to carry out single cavity (or cavity chain) measurement to certain radio frequency accelerating tube (see attached Figure 5 ), the main steps are as follows:

Description

technical field [0001] The invention belongs to the field of accelerators, in particular to a microwave parameter adjustment device for a radio frequency accelerator tube. Background technique [0002] In the field of radio frequency linear accelerators, after the acceleration structure of the radio frequency linear accelerator is initially processed according to the design, due to the influence of machining accuracy and machining errors, it is usually necessary to fine-tune the acceleration structure that does not meet the parameter requirements. At the same time, the determination of the parameters of the accelerated structure after preliminary processing and the fine tuning of the accelerated structure also involve the measurement of microwave parameters. [0003] Specifically, the tuning of the accelerating structure may involve the fine tuning of the accelerating cavity or coupler; while the measurement of microwave parameters may involve the measurement of a single acc...
