Abstract
The present invention discloses a beam energy selection system. The beam energy selection system comprises a device main body and an energy selection system. The front and the back of the vacuum cavity are connected with the beam line through a vacuum pipeline to provide a vacuum environment for facilitating the beam transmission therein, and the vacuum cavity is fixed and supported at a required position to keep the correctness of the beam line. The energy selection system includes a wedge graphite block, a motor driving system, a propelling system and a support structure. The wedge graphite block allows beams with different energy to pass through according to the different thickness of the graphitic layers to reach the effect of beam selection; the motor driving system drives the propelling system to make the graphite block forwards or backwards; the propelling system is connected with the graphite block and has the same movement with the graphite block; and the support structure supports the propelling system to ensure the motion stability. The beam energy selection system is simple to control, easy to operate and high in controllability, etc.
Description
Technical field
The present invention relates to line technical field, particularly relate to a kind of beam energy and select system.
Background technology
At present, line has started to be applied to each different field, such as electronic collision machine, proton therapeutic appts, ion treatment device etc..In order to obtain the particle of required different-energy, it is necessary to screen the particle of the different-energy collected from particle source, this is accomplished by one and filters with screening plant to complete this work.It is short that requirement must have higher reliability, seeervice cycle.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of beam energy selects system.
The present invention is achieved by the following technical solutions:
A kind of beam energy selects system, include vacuum cavity, before and after vacuum cavity, side is connected with beam line by vacuum line respectively, left and right sides outer wall at vacuum cavity is respectively fixed with fixing support, it is respectively equipped with driving motor in the side of fixing support, motor is driven to be provided with pushing ram, two pushing rams pierce into inside vacuum cavity from the left and right sides of vacuum cavity respectively, two pieces of graphite blocks it are provided with inside vacuum cavity, two graphite blocks are separately fixed at the end of pushing ram, the anterior end of two graphite blocks is provided with multiple wedge shape graphite, the mutually interspersed contact of the wedge shape graphite of two graphite blocks.
Vacuum cavity is fixed on fixed support structure, and ensures the direction of vacuum cavity and required to establish direction consistent, it is ensured that the transmission of line is not affected.
Motor driven systems drives pushing ram to carry out the motion advanced or retreat, and sphenolithus ink stick is connected with pushing ram, and graphite block can be made to advance in the direction of motion or retreat when motor forward or reverse.Advance or in fallback procedures at graphite block, the thickness of the graphite linings on the circuit that line passes through will be different, so particle beam of different-energy will pass through graphite block when graphite block different-thickness, thus the purpose that the particle beam in reaching to make specific energy range in certain time period passes through.Together with transmission support structure to be well fixed on vacuum cavity or fixed support structure, to ensure the stability in motor process.
The invention have the advantage that the present invention applies during beam transfer, the particle beam that can allow specific energy range passes through, shield the particle beam of unwanted energy range, thus according to user need particle beam energy is screened out and selects, can the more preferable purpose that must reach user；The present invention has the advantages such as control is simple, easy and simple to handle, controllability is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of beam energy selects system, include vacuum cavity 1, before and after vacuum cavity 1, side is connected with beam line by vacuum line respectively, left and right sides outer wall at vacuum cavity 1 is respectively fixed with fixing support 3, driving motor 4 it is respectively equipped with in the side of fixing support 3, motor 4 is driven to be provided with pushing ram 5, two pushing rams 5 pierce into vacuum cavity 1 inside from the left and right sides of vacuum cavity 1 respectively, two pieces of graphite blocks 6 it are provided with inside vacuum cavity 1, two graphite blocks 6 are separately fixed at the end of pushing ram 5, the anterior end of two graphite blocks 6 is provided with multiple wedge shape graphite, the mutually interspersed contact of the wedge shape graphite of two graphite blocks 6.
