Description
Technical field
The present invention is a kind of high current particle accelerator, and particularly accelerated current is strong, the dielectric wall accelerator accelerator module that accelerating gradient is high.
Background technology
Accelerator art has had significant progress through hundred years of development.The accelerator of various structures is being brought into play crucial effect in fields such as the national economic development, scientific research, health care, national defense construction.But present accelerator all has its weak point, and perhaps beam intensity is little, and perhaps accelerating gradient is low, perhaps involves great expense, and is billions of easily even tens billion of yuans.
At present, the high-current accelerator of comparative maturity is a linear induction accelerator.The polylith ferrite is equipped with in each accelerator module inboard of linear induction accelerator, during the high-voltage pulse input, form electric field in ferrite, and level produces accelerating voltage secondarily, to the particle acceleration of process.Its course of work can be described with " transformer model ": in accelerating cavity, the feed-in electric current of pulse power system flows into along the end face of accelerating cavity, and through quickening another end face of pipeline flow-direction accelerating cavity, this path has formed the elementary winding of single turn of transformer, Ferrite Material in the accelerating cavity is equivalent to the core material of transformer, and particle beam is equivalent to the single turn secondary winding of transformer.Accelerating cavity is equivalent to a transformer of 1: 1.Such accelerator module is connected in series, and the particle beams passes through each transformer successively, and energy just progressively is elevated to predetermined value.
This structures shape linear induction accelerator have following problem.
At first, particle only can obtain in (gaps between adjacent two accelerator modules) quickening between the accelerating gap of accelerating cavity end face, is in the state that freely drifts about at the accelerating cavity internal particle, can't obtain quickening.This just makes that the accelerating gradient of linear induction accelerator is very low, and the accelerating gradient height of each accelerator module is about 0.5-0.75MeV/m.A 20MeV linear induction accelerator generally is connected in series by more or less a hundred accelerator module, and about 0.5 meter of each accelerator module length is so take up an area of wide.
Secondly, in order to obtain certain voltage amplitude and pulse duration, i.e. the accelerating voltage pulse of certain " number volt-second ", need to use a large amount of expensive Ferrite Materials, accelerating voltage amplitude is high more, pulse duration is wide more, and the Ferrite Material that needs is just many more.In present actual engineering, the shared funds proportion of Ferrite Material is the each several part maximum, so linear induction accelerator involves great expense.
In addition, use Ferrite Material also can bring a problem, promptly ferritic reset issues.The course of work of linear induction accelerator is actually the process that a ferrite magnetizes, and after accelerator finished, ferrite had been in the state of magnetic saturation in fact; So,, need at first demagnetize promptly ferritic resetting in order to carry out accelerator next time.So, must have the complicated resetting means of a cover supporting with it.Because ferrite must have reseting procedure, linear induction accelerator is difficult to be operated under the high repetition frequency, and general working method is single pulse.
Therefore, because the restriction of acceleration principle, above-mentioned accelerator volume is big, cost is high, complex structure, operation maintenance difficulty.
The dielectric wall accelerator is a kind of novel high-current accelerator notion that newly puts forward in recent years, and it is strong to have an accelerated current, accelerating gradient height, simple in structure, the characteristics that cost is lower.But sort accelerator is accelerated electron, proton both, also can quicken heavy charged particle (for example carbon particle, potassium particle etc.), the radiograph that can be used for glistening, proton photograph, the conversion of nuclear power station nuke rubbish and processing, proton (or C
12Particle) field such as treatment cancer etc.Yet, both at home and abroad to the research of sort accelerator also seldom, more do not have the research of correlation engineering configuration aspects.
