Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] There is a very small gap of 20mm-30mm between the upper cover plate 2 and the lower cover plate 3 of the small cyclotron. In order to measure the magnetic field between extremely small gaps. This example proposes a figure 1 As shown, the fully automatic magnetic field measurement device suitable for small cyclotrons with a gap of 20mm-30mm includes a computer 1, a radial sheave drive mechanism 4, an angular drive mechanism 5, a central shaft 6, a measuring arm 7 and a slider 8.

[0019] The measuring arm 7 is installed in a gap of 20mm-30mm, the central axis 6 is set vertically, the upper end passes through the center hole of the accelerator lower cover 3 and is connected to the measuring arm 7, and the lower end is connected to the angular drive mechanism 5. See figure 2 , The measuring arm 7 is radially provided with a chute 10 along its central...

Abstract

The invention discloses a full-automatic magnetic field measurement device applicable to a mini cyclotron having a 20mm-30mm gap. The device comprises a computer, a radial rope wheel driving mechanism, an angular driving mechanism, a center shaft which is vertically arranged and driven to rotate by the angular driving mechanism, a measuring arm which is arranged in the 20mm-30mm gap and driven torotate by the center shaft as well as a sliding block which is arranged on the measuring arm and driven by the radial rope wheel driving mechanism to do reciprocating rectilinear movement along a sliding chute formed in the measuring arm, wherein the computer is respectively in telecommunication connection with the radial rope wheel driving mechanism and the angular driving mechanism and controlsthe measuring arm to move. The device disclosed by the invention solves the problems that an existing magnetic field measurement mode requires much time and effort, radial location is difficult and the probability that a human error appears is high.

Description

technical field [0001] The invention relates to the technical field of cyclotrons, in particular to a fully automatic magnetic field measuring device suitable for small cyclotrons with a gap of 20 mm to 30 mm. Background technique [0002] Small cyclotrons are widely used in hospitals to produce isotopes, and the energy is generally 10MeV-20MeV. The pole air gap is a parameter that needs to be considered in the design of this type of cyclotron magnet. The smaller the air gap is, the smaller the number of ampere-turns required to generate the same magnetic field is, which can greatly save energy consumption, but it is easy to generate beam current when the axial focus is small It hits the magnetic pole and loses it. With the proposal of the design concept of the magnet in the deep valley area, the axial focusing of the cyclotron is greatly improved. Very small air gaps, such as small low-energy cyclotrons with an air gap height of 20mm-30mm, have become popular. This will ...
