Device for dredging and cleaning of accelerating tube

Abstract

The invention relates to a device for dredging and cleaning of an accelerating tube. The device comprises a support, a worktable on the support, an accelerating tube clamping unit on the worktable, arotary dredging unit and a jet cleaning unit, wherein the rotary dredging unit and the jet cleaning unit are arranged on the two sides of the accelerating tube clamping unit respectively. The accelerating tube is fixed into the accelerating tube clamping unit, and after the rotary dredging unit dredges the interior of the accelerating tube, the inner wall of the accelerating tube is cleaned by thejet spraying unit. Compared with the prior art, by means of the device, dredging and cleaning of the accelerating tube can be achieved, the operation is simple, and the interior of the accelerating tube can be effectively dredged and thoroughly cleaned; dirt residues at the dead corners in the accelerating tube are eliminated, the cleaning effect is improved, wasting caused by replacement of theaccelerating tube is avoided, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of accelerators, and relates to a device for dredging and cleaning accelerator tubes. Background technique [0002] Accelerator is a device that increases the speed (kinetic energy) of charged particles, which can be used in nuclear experiments, radiological medicine, radiochemical, radioactive isotope manufacturing, non-destructive flaw detection, etc. There are many types of accelerators, mainly cyclotrons, linear accelerators, electrostatic accelerators, particle accelerators, voltage doubler accelerators, etc. Among them, the Varian linear accelerator is one of the most advanced special equipment for radiotherapy in the world. It has multiple energy combinations of photon beams and electron beams to meet clinical needs. It can not only perform conventional radiotherapy techniques, but also image-guided radiotherapy techniques, Intensity-modulated radiotherapy technology, rapid rotation volume intensity-...

AI Technical Summary

Problems solved by technology

During the use of the Varian linear accelerator, as the use time increases, the acceleration tube often appears blocked in the tube

Due to the complex internal structure of the accelerating tube, it is difficult to dredge and clean. Therefore, if the accelerating tube is blocked, generally the new accelerating tube can only be replaced directly, which greatly increases the cost.
