Problems solved by technology

[0003] The existing conventional permanent magnet ring is made of NdFeB material, which is characterized by high hardness and fragility. The magnetization remanence of the conventional permanent magnet ring is on the order of T, and the magnetic ring and the iron ring or the magnetic ring and the magnetic ring are close to each other. The magnetic force when the distance is in contact is very large, which will make the assembly between the magnetic ring and the iron ring or between the magnetic ring and the magnetic ring (coaxial installation of the magnetic ring and the magnetic ring or the magnetic ring and the iron ring) difficult, and often occur during the assembly process. Breaking the magnetic ring, and a sudden collision will lead to a decrease in the magnetic field strength, resulting in failure of the experiment or waste of time and economic loss
[0004] The above-mentioned existing technical solutions have the following defects: in the prior art, there is a lack of a permanent magnetic ring installation structure that can prevent the magnetic ring from being smashed and simplify the assembly process of the permanent magnetic ring

Abstract

The invention relates to the field of permanent magnet type ECR ion sources, and particularly relates to a permanent magnet ECR ion source permanent magnet ring mounting structure and a processing method thereof. The structure comprises a movable bar material and a static bar material which are both made of non-magnetic materials and have the same inner diameter as a permanent magnet ring to be installed; a positioning rod coaxial with the movable bar material is arranged at one end of the movable bar material, an arc-shaped guide groove allowing the positioning rod to slide is formed in the end face of the static bar material and the guide groove passes through the axis of the static bar material so that the effects of simplifying the assembling process of the permanent magnet ring, saving time and labor and reducing the possibility that the magnetic ring is crushed are achieved.

Description

technical field [0001] The invention relates to the field of permanent magnet ECR ion sources, in particular to an installation structure of a permanent magnet ring of a permanent magnet ECR ion source and a processing method thereof. Background technique [0002] Currently in the field of permanent magnet ECR ion sources, the electron cyclotron resonance magnetic field is provided by a permanent magnet ring and a magnetically conductive iron ring or a permanent magnet ring and a permanent magnet ring. [0003] The existing conventional permanent magnet ring is made of NdFeB material, which is characterized by high hardness and fragility. The magnetization remanence of the conventional permanent magnet ring is at the T level. The magnetic force when the distance is in contact is very large, which will make the assembly between the magnetic ring and the iron ring or between the magnetic ring and the magnetic ring (coaxial installation of the magnetic ring and the magnetic rin...
