Post
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, 2, be this utility model provide control the mutually wide device of superconducting cyclotron line, this setting
On the magnetic pole 8 of Low Energy Region, superconducting cyclotron center, it includes support bar 5 and the interior bar 4 being located in support bar 5, interior
The head of bar 4 is arranged side by side two collimation posts 1,2, forms the slit of one fixed width between two collimation posts 1,2, when the footpath of bundle group
When size is more than the width of this slit, some particles is got to and is lost on two collimation posts, thus it is mutually wide to control line, it is to avoid
The radiation dose brought and parts activation is lost at draw-out area high energy particle.
Support bar 5 is the column construction of eccentric hollow, is spindle rotationally arranged on magnetic pole 8, is driven by motor and realizes turning
Dynamic, thus coarse adjustment collimates position and the direction of slit between post 1,2.Support bar 5 can be selected for non-magnet material, reduces the damage of magnetic pole
Consumption.
Interior bar 4 is solid column construction, moving up and down is arranged in support bar 5.Interior bar 4 is pneumatic by compressed air
Driving realizes it and moves up and down, and can be driven by motor simultaneously and realize rotating, thus finely tune the position of slit between collimation post 1,2
And direction.Non-magnet material also selected by interior bar 4, reduces the loss of magnetic pole.The interior internally installed water cooling labyrinth of bar 4, for the coldest
But two collimation posts 1,2, it is ensured that the normal temperature of two collimation posts, it is to avoid at high temperature work for a long time, reduce the life-span.
The head of two collimation posts 1,2 sets a pallet 3 altogether, is used for fixing two collimation posts 1,2, two collimation posts and torr
Dish 3 can move up and down along with interior bar.
As it is shown on figure 3, this utility model can be mutually wide at two control lines of Low Energy Region, superconducting cyclotron center placement
Device 6,7, and two control the mutually wide devices 6,7 of line and be individually positioned in the same radius on the line of symmetry of adjacent pole 8
Place, this utility model is installed two mutually wide devices of line simultaneously, can be controlled line more effectively, for greater flexibility mutually wide.
This utility model is achieved in that on two adjacent magnetic poles 8 one hole of each brill, is used for placing support bar 5,
Support bar 5 can rotate around its axle center.Support bar 5 endoporus installs an interior bar 4, and interior bar 4 can move up and down.4, interior bar
Portion's two cylindrical collimation posts 1 and 2 being made up of radiation hardness, exotic material placed side by side, the head of two collimation posts 1 and 2
Portion arranges a pallet 3.Thus, support bar 5 just can realize collimating post 1,2 in the radial direction of accelerator and the position of azimuth direction
Mobile, the effective width of slit changes the most therewith, thus changes the radial direction acceptance of this collimator, stops those the most remote
Particle from designed path.Support bar 5 is driven by motor and rotates, and interior bar 4 is by compressed air pneumatic actuation phase level
Straight device lifts, it is achieved the purpose of flexible Application.When needing big Bunch current, the collimation of the mutually wide device of line will be controlled
Post moves apart central plane, it is achieved multi-turn is drawn；And when needing raising ejection efficiency to realize individual pen extraction, then will control line mutually wide
The collimation post of device move on to central plane.Thus, the device that control line of the present utility model is mutually wide, simple in construction, use
Flexibly.
Below as a example by an extraction proton energy is 230 million electro-volts of superconduction bevatrons, to being embodied as
Mode is further described.This accelerator has four spiral type magnetic poles 8, makes a call to a through hole near the position of stem stem 9 at magnetic pole 8,
Install two and control the device 6,7 that line is mutually wide.When needs individual pen is drawn, utilize pneumatic actuation will draw from center region
The particle beam group gone out can control in the range of 8 ° by mutually wide for line after twice collimation, reduces bundle group radial dimension, reduces
The loss on extraction elements of the high energy region line, thus reduce educt beaming flow loss and accelerator activation.
