The invention discloses a device and a method for measuring the deflecting plate electrode interval of the charged particle of a cyclotron. The device comprises an assembling gap gauge, a measuring tool bottom plate, a measuring tool slab, regulation bolts, level bubbles, dial indicator clamping parts and dial indicators, wherein the dial indicator clamping parts, dial indicators and the level bubbles are all fixed on the measuring tool slab, and the assembling gap gauge is assembled between a high-voltage electrode and a beam current cutting film. The device has the beneficial effects that adistance between the high-voltage electrode and the beam current cutting film of the deflecting plate can be accurately measured so as to be convenient in accurately calculating the practical electricfield intensity of deflecting beam current. Meanwhile, an aluminum alloy material can be adopted to lower the weight of the measuring device, lower processing difficulty and reduce manufacture cost.The device is convenient in operation, is firm and durable, has good social benefits and is suitable for promotion and use.
Description
technical field [0001] The invention relates to a device for measuring the distance between deflecting plates, in particular to a device and method for measuring the distance between charged particles in a cyclotron and belonging to the technical field of measuring devices for measuring the distance between deflecting plates. Background technique [0002] With the current rising demand for cancer treatment, proton therapy has become an effective means of treating tumors. Because of the energy distribution characteristics of the Bragg peak of the proton in the material, by controlling the position of the proton Bragg peak, it can effectively kill the lesion while reducing the damage to the surrounding healthy tissue. The superconducting proton cyclotron is the core component of the proton medical system. Compared with the normal temperature cyclotron, the superconducting proton cyclotron has the advantages of compact structure and low operating power loss. Among them, the de...
