Description
Technical field
The utility model relates to technical field of plasma more particularly to a kind of ceramic water cooling can not draw the radio frequency-ion
Source.
Background technique
Neutral beam injection system (Neutral Beam Injection, NBI) has heating efficiency high, and physical mechanism is most clear
The characteristics of Chu is important one of the auxiliary device of EAST tokamak.Ion source is critical component in neutral beam injection system, greatly
The neutral beam injection device of power is necessarily required to the support of high current ion source.With both at home and abroad to the continuous of neutral beam injection system
Development, it is also more and more to the research of high current ion source.The RF ion source of external antenna structure is all made of ceramics both at home and abroad at present
Or quartz glass insulation, since internal power deposition and plasma sputtering can make in ceramics or quartz glass insulating layer temperature
Rising leads to structural damage.Inside must install Faraday cup and be protected, which mainly has the disadvantage that:
(1) Faraday cup cooling water channel difficulty of processing is big, a large amount of water routes need to by the way of vacuum brazing difficulty of processing it is big
And it is at high cost；
(2) Faraday cup barrel can only generally process the section cooling water channel of 4mm or so, and cooling effect is poor；
(3) Faraday cup shielding causes coil to be difficult feed-in effective power；
(4) Faraday cup structure increases the debugging difficulty of experimenter；
(5) it needs complex from internal vacuum chamber extraction cooling water pipe sealing structure and needs to occupy certain space；
(6) it needs to do potential isolation to Faraday cup.
Utility model content
The utility model aim is exactly that in order to make up the defect of prior art, providing a kind of ceramic water cooling can not draw the barrel to penetrate
Frequency ion source.
The utility model is achieved through the following technical solutions:
It is a kind of ceramics water cooling can not draw the radio-frequency ion source, include double-layer ceramic cylinder, the double-layer ceramic cylinder
Inside and outer layer intermediate gaps are cooling water channel, radio-frequency coil are wound on the outside of double-layer ceramic cylinder, in double-layer ceramic cylinder
Top and bottom are respectively equipped with the inlet and outlet communicated with cooling water channel, and the top and bottom of double-layer ceramic cylinder are solid respectively
Surely there are upper flange and lower flange, be also sealed and installed with ion source cover board in the upper end of double-layer ceramic cylinder, pacify on ion source cover board
Equipped with starting filament and inlet duct.
The ion source cover board is fixed on the upper end of double-layer ceramic cylinder by viton seal ring and M6 hexagon socket head cap screw.
The top and bottom of the double-layer ceramic cylinder pass through vacuum brazing respectively and are welded on upper flange and lower flange.
There are four the inlet and outlet are equal.
Traditional ceramics or quartz outer are mainly substituted for double-layer ceramic by the design of radio-frequency ion source ceramics water-cooling structure
Structure is passed through cooling water temperature inside double-layer ceramic to effectively prevent ceramic temperature rising to play the role of protection, due to pottery
Porcelain inner wall, which can independently cool down, does not need the protection of faraday's bucket, therefore can remove faraday's bucket.
Ceramic cylinder inner wall internal diameter is 198mm, with a thickness of 4mm, be highly 150mm, outer wall outer diameter is 226mm, with a thickness of
It 4mm, is highly 150mm, hollow spacing is 6mm between two ceramic cylinders, and it is 300mm that two flange thicknesses, which are 20mm outer diameter,.
Cooling water is passed through by the water inlet that four diameters are 12mm inside double-layer ceramic to cool down ceramic wall, and is led to
It crosses the water outlet discharge hot water that 4 diameters are 12mm and realizes autonomous cooling.
Traditional ceramics or quartz outer are mainly substituted for double-layer ceramic by the design of radio-frequency ion source ceramics water-cooling structure
Structure.Cooling water temperature is passed through inside double-layer ceramic to effectively prevent ceramic temperature rising to play the role of protection.Due to pottery
Porcelain inner wall, which can independently cool down, does not need the protection of faraday's bucket, therefore can remove faraday's bucket.Advantage without faraday's bucket
Be: processing cost simply greatly reduces in radio frequency-ion source structure；There is no Faraday cup shieldings, are more advantageous to coil
Power obtains feed-in；Structure, which is simply conducive to experimenter, to debug；Radio-frequency ion source inner vacuum body is not take up under identical structure
Product, so that plasma generator effective volume increase is conducive to the generation of higher power.
Ceramic water-cooled cylinder is brazed in upper and lower cover plates using double-layer ceramic structure, and inside can be passed through cooling water temperature.When
When radio-frequency ion source works, plasma can act directly on ceramic inner walls and temperature is caused to rise, and cooling water can play drop at this time
Temperature effect is to protect ceramic bucket inner wall not to be damaged.Because the available effective temperature-reducing protection of ceramic bucket is so farad can be removed
Barrel structure is to simplify radio frequency-ion source structure.
The utility model has the advantages that: the utility model is simply greatly reduced using no faraday's barrel structure structure to be added
Work cost；There is no Faraday cup shieldings, are more advantageous to coil power and obtain feed-in；Structure, which is simply conducive to experimenter, to be adjusted
Examination；There are the gaps 6mm can be passed through a large amount of cooling waters between two-layer ceramic bucket, and but effect is preferable for water；It is not take up under identical structure
Radio-frequency ion source inner vacuum volume, so that plasma generator effective volume increase is conducive to the generation of higher power；Nothing
The design of faraday's bucket is without the concern for faraday's bucket potential isolation problem.
