Background technology
On April 28th, 1994 to May 5 is after the seminar that Belgium holds, by at CERN Accelerator School, Cyclotrons, Linacs and Their Applications, Geneva96 (Geneva 96, CERN accelerator school, cyclotron, linear accelerator and their application) article " cyclotron in the radiotherapy " (CYCLOTRONS INRADIOTHERAPY) delivered, we know the cyclotrons that have two to put side by side on the accelerator, and the one-level cyclotron is used for speeding-up ion H
-, the secondary cyclotron, be otherwise known as " booster " is at the neutral particle H of one-level cyclotron generation
0After line passed electron stripper (é plucheur), the secondary cyclotron was used for accelerating proton H
+Such accelerator is quite complicated, and structure is huge.
Summary of the invention
The present invention is a kind of novel particle accelerator, comprises at least
An one-level cyclotron;
A secondary cyclotron, the periphery that it is centered around this one-level cyclotron is used to quicken the particle that this one-level cyclotron produces.
The present invention can have the advantage of the accelerator of dependable performance, can produce the intensive line of high energy particle.In view of the installation site of two cyclotrons mutually around, equipment volume is dwindled thus, and has simplified the one-level cyclotron and quickened the process that the back charged particle is injected into the secondary cyclotron.Especially the meridian plane of firsts and seconds cyclotron obviously is a coplane, make the particle be accelerated fly away from the one-level cyclotron like this and needn't do vertical deflection before being injected into the secondary cyclotron, thereby can save magnetic deflection electrode and/or electrostatic deflection electrodes, and can when activated equipment, reduce the loss and risk.At last, the tracks between two cyclotrons can be quite short, alleviated the problem of space charge.
The one-level cyclotron is a compact, with the sort of to separate the fan type opposite.The secondary cyclotron is to separate fan type cyclotron.
So-called " compact cyclotron ", being construed as has at least one belt coil to be connected on its magnet on this accelerator.So-called " separating fan type cyclotron ", a plurality of independently field regions have been construed as.Can be referring to the article of enumerating previously of having delivered, its content here is mentioned as a reference.
The one-level cyclotron can be a superconductor, also can not be.
According to the present situation of invention, the particle properties difference in the particle beam that the firsts and seconds cyclotron quickens.
Like this, in the example of an application, in the line that the one-level cyclotron quickens molecular ion is arranged, such as, IONS OF H
2 +Perhaps H
3 +Accelerator has a stripper, and the secondary cyclotron is intercepted and captured the particle beam that the one-level cyclotron is drawn by stripper, and quickens this line.The line that the secondary cyclotron quickens can be by proton H
+Form.
So-called " stripper " also is called " separator ", is the paillon foil device that a particle beam can pass through.This paillon foil is to be made by the material that can " intercept and capture " some particle element, such as, can stop electronics e
-, and allow other compositions pass through.The very thin carbon paper tinsel of one deck can be arranged in the stripper.
In one embodiment of the invention, stripper is an electron stripper, and it can intercept and capture the electronics that belongs to molecular ion in the line that the one-level cyclotron sends, thereby forms the proton H in the line that the secondary cyclotron quickens
+
In an application example of the present invention, stripper is in the inside of secondary cyclotron, in the gap of field region.
Accelerator also has one axially to inject line, and it is connected with ion source on the one hand, for example, and ion source H
2 +Perhaps H
3 +, on the other hand, it is connected with the one-level cyclotron again.
According to the present situation of invention, accelerator has a control device, is used for measuring and controlling the current strength that stripper sends.Adjuster (l ' acc é l é rateur) can change the intensity of the particle beam that the one-level cyclotron quickens according to the data of this electric current and set-point.
Adjuster has a high frequency bunching system at least, also is called " buncher ", the injection particle of the one-level cyclotron that is used to recombinate, and this bunching system belongs to the axial injection line that the front has been mentioned.
The design of one-level accelerator, make accelerated particle before flying away from the one-level accelerator, will rotate about 10 to 30 circles, the number of turns that this like-particles rotates in the one-level cyclotron can be suitable lack, make that the gap between the different tracks of particle is quite big, quite easily educt beaming flow on last track.Like this, the particle beam of one-level cyclotron acceleration can just fly away from the one-level cyclotron through stripper.
The invention still further relates to a kind of purposes of accelerator, can utilize the accelerator of setting forth previously to provide energy to the system that accelerator drives, be known as " accelerator drives nuclear power system (ADS) ", capital equipment has:
An energy amplifier,
A subcritical nuclear reactor, perhaps
A nuke rubbish transmuting device (transmuteur).
Conscientiously read following detailed description,, will more deep understanding be arranged the present invention referring to being not after the use-case and accompanying drawing that is used to limit.
