Description
Technical field
The present invention relates to vacuum technique, accurately rotate control technology and magnetic confinement fusion field, be specifically related to a kind of Plasma disruption and protect the special accurate Automatic Provisioning System of many lithiums ball bullet.
Background technology
In Tokamak discharge test, due to reasons such as plasma control, hydromagnetic instability, impurity, high energy escape particles, make breaking of plasma be difficult to avoid.Particularly realizing the main research of Tokamak Fusion Reactor steady-state operation-maintain in the electric discharge of stable state high parameter plasma, Plasma disruption electric discharge can cause serious destruction, heat load as large in the first wall, strong mechanical stress, large escape electric current etc., even to inclined to one side worry device target plate, the first wall components even device cause major injury.Although the operational limit of the different parameters of existing Tokamak discharge has had deep research, and can control tokamak in " safe operation " region and the generation of avoiding breaking, but always having some to break is difficult to avoid, therefore, for the harm that bigger device is caused of breaking of Avoids or reduces under high parameter condition, the research of carrying out Plasma disruption alleviation is necessary and is very important, is also one of emphasis of working as the research of forestock Karma card plasma physics.
Plasma disruption protection is mainly divided into initiatively protection and two kinds of modes of passive protection, and initiatively protection is mainly to control plasma discharge parameter by FEEDBACK CONTROL, makes it move plasma safety zone and avoids breaking; Passive protection is mainly to those taked modes of inevitably breaking, alleviate to the mode of implanted dopant in plasma the brought harm of breaking, it mainly contains two kinds of methods, one is that bullet injects, and one is that gases at high pressure inject, and two kinds of Impurity injection modes have pluses and minuses separately, inject for bullet, due to material densification, therefore bullet can be injected into plasma core, but the bullet injected system complicated structure using at present and be all from external introduction; Inject for gases at high pressure, the systematic comparison of this kind of injection mode needs is simple, but owing to being gas inject, due to ionization effect, foreign gas can only enter into plasma boundary region, is difficult to enter into plasma core area.
Inject the shortcoming that can only be injected into edge plasma region in order to overcome bullet injected system complexity and gases at high pressure, we inject on the successful basis of developing of fast filling valve (201110090285) and have have successfully researched and developed many bullets injection gases at high pressure propulsion systems at gases at high pressure, and this system comprises a set of fast filling valve and a set of many lithiums ball bullet injects accurate Automatic Provisioning System.Experimental demand, inject accurate Automatic Provisioning System by many lithiums ball bullet and place the lithium ball bullet of some in the position, gas outlet of fast filling valve, fast filling valve obtains will spraying one high pressure draught after triggering signal lithium ball bullet is accelerated to the speed of hundreds of rice, thereby lithium ball bullet can be injected into plasma core as common bullet, gases at high pressure impurity can be injected into edge plasma region, like this, cooling when just realizing plasma core and edge, this plasma break alleviate more favourable.
Many lithiums ball bullet injects succeeding in developing of accurate Automatic Provisioning System, concerning EAST tokamak device, have great significance, succeeding in developing of it, indicate a kind of successful realization that bullet injects and gases at high pressure inject the novel Impurity injection mode of two kinds of Impurity injection mode advantages that combines, this provides effective Impurity injection instrument to carry out the work of Plasma disruption Protective Research on EAST later.EAST, as the full superconduction divertor device of first class ITER in the world, breaks thereon and alleviates experiment, also can for ITER fusion facility provide experiment basis and data with reference to and accumulation.
