Abstract
The utility model relates to a superconducting high-charge state ECR ion source, which comprises a shell. The outside of a cavity of the ion source is sheathed with an axial superconducting wire packet A, fixing soft irons in inner rings and an axial superconducting wire packet C. An axial superconducting wire packet B is clamped between the fixing soft irons in inner rings and block-shaped fixing soft irons of a radial wire packet. At least four radial superconducting wire packets are arranged on the radial and symmetrical position of the external side of the axial superconducting wire packets A, B, C. The radial superconducting wire packet is fixed by block-shaped fixing soft irons of a radial wire packet. The outside of the radial superconducting wire packet and the external side of the axial superconducting wire packets A and C are fixed by fixing soft irons A on an axle end and fixing soft irons B in outer rings. All the superconducting wire packets and the fixing soft irons are arranged in liquid He-Dewar. The Dewar is connected with a refrigerating machine. The utility model has the advantages that the field intensity of a magnetic mirror field is high, an axial field and a radial field are greatly enhanced, and mutual force between each wire packet is reduced; besides, the utility model has compact structure.
Description
The utility model relates to the ecr ion source of using in a kind of nuclear physics experiment.
The ionogenic operation principle of high charge state ECR (electron cyclotron resonace) is: microwave enters the ionogenic cavity from injection end, this cavity is the part of vacuum system, in fill working gas, when microwave frequency equals the electron cyclotron motion frequency, resonance will take place and absorb energy from microwave in portions of electronics, electronics accelerates to very high-energy, produces the high charge state ion by ionization by collision step by step; The axial magnetic-mirror field that ionogenic in addition axial superconducting line bag forms; Radially the superconducting line bag forms radially sextupole magnetic field, and two magnetic field superpositions form magnetic confinement.Axially magnetic-mirror field has minimum value in cavity central authorities, and plasma keeps high density herein, the high charge state ion finally through the aperture of plasma electrode by the extraction electrode sucking-off.Because but ecr ion source has long-term stable operation, restriction in no useful life, and be the effective tool that the strongest high charge state ion flow can be provided at present, thereby be widely used in heavy ion avcceleration, and on the accelerator of other types, use and also show a rising trend.This is mainly due to along with the raising that is accelerated the ionic charge attitude, increase (the ion energy W-Z that the energy that ion finally is accelerated can become square
2, wherein W is the energy that ion is accelerated, Z is the charge state number of ion); Thereby when identical, during the ion of an accelerated band Z electric charge (as quickening), can make the accelerating voltage of linear accelerator reduce Z doubly, thereby can obviously reduce the operating cost of accelerator with linear accelerator for the ion energy that is accelerated.Therefore, except that accelerator was used, emerging high ionization Atomic Physics experiment condition also had only the ECR source just can provide now at present.Need the trend in ECR source also day by day to rise in addition in the industrial or agricultural field, particularly this provenance has been used for material surface modifying in the world, semiconductor oozes applications such as slag.Based on these advantages, the development in ECR source is maked rapid progress in the world, generally speaking, improve axial magnetic-mirror field and radially hexapole field, improve the yield that microwave frequency can improve the high charge state ion significantly.The axial magnetic-mirror field of ECR Ion Source of High Charge States of utilizing conventional room temperature line bag to be built at present is the highest can only to reach 1.7T.Existing in the world and the superconduction ECR source of building, conventional line bag ECR source are the outside that axial magnetic field wire bag wraps in radial magnetic field line bag or permanent magnet in addition, concerning the normal temperature ion source, such structural advantages is a lot, but for the superconduction source, but there is very big shortcoming in this structure, it makes and produces enormous function power between the line bag, and the component on all directions is tens thousand of newton.The small slip in any point therebetween all can cause quench.
The purpose of this utility model is for a kind of magnetic-mirror field field intensity height being provided, improving axial field, radial field significantly, between two kinds of line bags active force reduce, the superconduction ECR Ion Source of High Charge States of compact conformation.
The purpose of this utility model can realize by following measure:
A kind of superconduction ECR Ion Source of High Charge States comprises shell; Be with axial superconducting line bag A, interior ring fixedly soft iron and axial superconducting line bag C in the outside of ion source cavity, fixedly soft iron and radial transmission line enclosed mass shape fixedly between the soft iron of ring in axially superconducting line bag B is clipped in; Radial symmetric position outside axial superconducting line bag A, B, C is provided with 4 radially superconducting line bags at least; Radially the superconducting line bag by radial transmission line enclosed mass shape fixedly soft iron fix; Radially the superconducting line bag and axially superconducting line bag A, C the outside by axle head fixedly soft iron A, B and outer shroud fixedly soft iron fix, all superconducting line bags and fixedly soft iron all place liquid He Dewar, this Dewar and refrigeration machine link.
The utility model has following advantage compared to existing technology:
1, the utility model places axial superconducting line bag within the radial transmission line bag, can reduce line bag active force each other, has avoided conventional axial line to wrap in the very big defective of component between each line bag outside radial transmission line bag or the permanent magnet, has avoided quench.
2, the utility model utilizes soft iron to increase substantially axial field between axial and radial transmission line bag, and these soft irons are used for the fastened tools of superconducting line bag simultaneously.
3, the utlity model has higher axial magnetic-mirror field, adopt less arc chamber, higher magnetic-mirror field makes its compact conformation, realizes commercialization easily.
