Embodiment Construction

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Such as Figure 1-3 As shown, an accelerating tube 100 is disclosed. The accelerating tube 100 is exemplarily an edge-coupled standing wave accelerating tube, which includes a plurality of accelerating cavities 102, 104, 106, 108 and adjacent accelerating cavities 102, 104, 104, 106, and 106, 108. Coupling cavities 110, 112, 114. The drift tube 116 defines a beam channel between the acceleration cavities 102, 104, 106, and 108. As shown in the figure, in this exemplary embodiment, the side coupling cavities 110, 114 adopt a common design, that is, the side coupling cavities 110, 114 have upstream and downstream nose cones opposite to each other. Each nose cone divides the respective side coupling cavity into a pa...

Abstract

Disclosed is an accelerating tube. The accelerating tube comprises a plurality of accelerating cavities,at least one coupled cavity and an adjustment assembly. The coupled cavities are coupled to two adjacent accelerating cavities in a plurality of accelerating cavities, cavity walls of the coupled cavities are elastically deformable within a predetermined range, the adjustment assembly is disposed outside of the coupled cavities, the adjustment assembly comprises at least a actuating part and a driving parts, the actuating parts are coupled to the cavity walls of the coupled cavities driven by the driving parts, The cavity walls of the coupled cavities are elastically deformable by the effect of the actuating parts to change the output energy of the accelerating tube.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an acceleration tube. Background technique [0002] The accelerator tube is a key component of the medical electron linear accelerator, and its role is to generate high-energy rays for clinical cancer treatment and imaging. However, in order to improve the accuracy of clinical cancer treatment, many medical electronic linear accelerators are currently developing medical accelerator tubes that can simultaneously output keV-level rays for imaging. The keV-level ray is generally realized by setting a switch with energy modulation function on the accelerator tube. At present, the acceleration tube with energy switch with keV-level imaging function is generally assembled by brazing and knife-edge sealing flanges. Completed, such as the CL2300 series of Varian currently on sale. [0003] Most of the prior art is to add an external metal adjustment structure to a certain side coupling cavity...
