Referring to Fig. 1-Fig. 3, accelerator installation 1 according to embodiments of the present invention is described.As shown in Figure 1-Figure 3, accelerator installation 1 according to embodiments of the present invention includes accelerating tube 100, target spot 200 and zero collimator 300.
Target spot 200 is located at the front end (wherein shown in the arrow in fore-and-aft direction A such as Fig. 1-Fig. 3) of accelerating tube 100.Zero collimator 300 has collimating slit 310 through for A along the longitudinal direction, the front end of accelerating tube 100 is connected with the rear end of zero collimator 300, and accelerating tube 100 relative to zero collimator 300 on left and right directions B translatable to regulate the accelerating tube 100 position (wherein left and right directions B is as shown by the arrows in figs. 2 and 3) relative to zero collimator 300, so that the center of ray line alignment collimating slit 310, improve the utilization rate of beam.
The work process of accelerator installation 1 according to embodiments of the present invention is described referring to Fig. 1-Fig. 3.After charged particle accelerates in accelerating tube 100, form beam by clashing into target spot 200.Operator regulate the relative position of accelerating tube 100 and zero collimator 300 by translational acceleration pipe 100, make line be directed at the collimating slit 310 of zero collimator 300, and described beam forms reservation shape by zero collimator 300.
The accelerating tube 100 of accelerator installation 1 according to embodiments of the present invention relative to zero collimator 300 on left and right directions B translatable, such that it is able to regulated the relative position of the collimating slit 310 of described line and zero collimator 300 by translational acceleration pipe 100.Traditional accelerator installation is by swinging the position that accelerating tube regulates the collimating slit of line and zero collimator, and degree of accuracy is poor, and the major part of line can be mapped on the wall of collimating slit, and the utilization rate of beam is relatively low.Accelerator installation 1 according to embodiments of the present invention regulates the relative position of the collimating slit 310 of described line and zero collimator 300 by translational acceleration pipe 100, that is, in adjustment process, the axis of accelerating tube 100 is parallel to the collimating slit 310 of zero collimator 300 all the time, thus ray line can be directed at the center of collimating slit 310, thus having higher beam utilization rate.
Fig. 1-Fig. 3 illustrates accelerator installation 1 according to an embodiment of the invention.As shown in Figure 1-Figure 3, the rear end of zero collimator 300 can be provided with chute 320, and the front end of accelerating tube 100 can be provided with and the slide protrusion 110 of chute 320 adaptation, and slide protrusion 110 can coordinate movably in chute 320.By arranging chute 320 in the rear end of zero collimator 300, arrange slide protrusion 110 in the front end of accelerating tube 100, such that it is able to accelerating tube 100 can be translationally arranged on zero collimator 300 left and right.
Specifically, as in figure 2 it is shown, chute 320 can B be horizontal-extending in left-right direction, so it be possible not only to facilitate operator to move accelerating tube 100, and be possible to prevent accelerating tube 100 under gravity out of position.In other words, if B is not horizontal-extending in left-right direction for chute 320, accelerating tube 100 can not easily be fixed on described precalculated position (wherein said precalculated position refers to that operator want the optional position that accelerating tube 100 stops) because of action of gravity.Wherein, at least open at one end in the left end of chute 320 and right-hand member, that is, or the left end of chute 320 opens wide, or the right-hand member of chute 320 opens wide, or the left end of chute 320 and right-hand member are all unlimited, thus the slide protrusion 110 of the accelerating tube 100 front end left end by chute 320 or right-hand member can be slipped in chute 320.
It will be understood that chute 320 can also be located at the front end of accelerating tube 100, and slide protrusion 110 can be located at the rear end of zero collimator 300.
Fig. 1-Fig. 3 illustrates the accelerator installation 1 according to one concrete example of the present invention.As shown in Figure 1-Figure 3, chute 320 can be dovetail groove or T-slot, and slide protrusion 110 can be configured to the swallow-tail form suitable with chute 320 or T-shaped.So can utilize wall stop slide protrusion 110 on fore-and-aft direction A of chute 320, it is prevented that slide protrusion 110 is moved rearwards by and deviates from chute 320, thus strengthening the structural stability of accelerator installation 1.
Alternatively, as shown in figures 1 and 3, the front end of slide protrusion 110 can preset distance spaced apart with the diapire 321 of chute 320, target spot 200 can be located at the front end of slide protrusion 110.In other words, target spot 200 and slide protrusion 110 are respectively positioned in chute 320.So simplify the structure of accelerating tube 100, reduce the production cost of accelerating tube 100.Wherein, the front end of slide protrusion 110 preset distance spaced apart with the diapire 321 of chute 320, for dodging the target spot 200 of the front end being located at slide protrusion 110.
Specifically, can have, in slide protrusion 110, the cavity being connected with the accelerating cavity of accelerating tube 100 so that the charged particle in described accelerating cavity clashes into target spot 200 by described cavity.Chute 320 on zero collimator 300 can be connected with collimating slit 310 so that beam enters collimating slit 310 by chute 320.
As it is shown on figure 3, target spot 200 can be located at the center of the front surface of slide protrusion 110.The structure being thus possible not only to make accelerator installation 1 is more reasonable, it is also possible to make operator regulate the relative position of collimating slit 310 of line and zero collimator 300 more easily.
Advantageously, accelerating tube 100 and slide protrusion 110 may be integrally formed, and so can strengthen accelerating tube 100 and the intensity of slide protrusion 110 junction, improve the structural stability of accelerator installation 1 further, and the generation technique of accelerator installation 1 can be simplified, thus reducing production cost.
Figures 1 and 2 show that the accelerator installation 1 according to one example of the present invention.As depicted in figs. 1 and 2, collimating slit 310 can have rectangular shape on the cross section being orthogonal to fore-and-aft direction A, the long limit of described rectangle can along the vertical direction C extend and described rectangle minor face can in left-right direction B extend (wherein shown in the arrow in above-below direction C such as Fig. 1-Fig. 3, left and right directions B is as shown by the arrows in figs. 2 and 3).
In radiation detection system, it is typically provided with the transporter moved of B in left-right direction, drives article B in left-right direction to be detected to move by described transporter, so that every part of described article to be detected both passes through radiation detection area.
As it is shown in figure 1, collimating slit 310 can have trapezoidal shape on the cross section being orthogonal to left and right directions B.Specifically, described trapezoidal long base is positioned at the front on described trapezoidal short base.So can improve zero collimator 300 collimating effect to line, in the vertical direction expands the radiation detection area (wherein vertical direction is consistent with above-below direction C) of accelerator installation 1, make accelerator installation 1 can detect higher article, thus strengthening the practicality of accelerator installation 1.
Alternatively, as it is shown in figure 1, can be provided with ring flange 400 between accelerating tube 100 and zero collimator 300, ring flange 400 can be detachably connected with zero collimator 300 with the position of fixing accelerating tube 100.By arranging ring flange 400, it is possible to fix the position of accelerating tube 100 after the center alignment of ray line and collimating slit 310 to prevent accelerating tube 100 from moving.
Accelerator installation 1 according to embodiments of the present invention can make line align with the collimating slit 310 of zero collimator 300, has higher beam utilization rate.
