Description
Technical Field
The invention belongs to the technical field of cyclotrons, and particularly relates to a working platform and a method for realizing target bar swing of a stripped target in a narrow space.
Background
In the cyclotron, the accelerated particles can adopt a stripping extraction mode, after the particles are accelerated to a specified energy, the particles pass through a stripping film at a specified position, certain charges are stripped off, the particles are converted into particles with reverse potential with the original particles, and a particle beam is extracted along an extraction track, so whether the stripping film accurately reaches a designed stripping point is the key point of whether the extracted beam can be stripped or not, and whether the accelerator can reach one of the key points of the design and the use performance.
Since the accelerator usually needs to extract particles with different energies, the particles with different energies correspond to particle tracks at different positions and correspondingly to stripping points on arcs with different radii in the extraction area, if only depending on the forward and backward movement of the target rod, the stripping points on the arcs with different radii cannot be completely covered, and therefore, the target rod needs to swing while moving forward and backward; because the initial position of target pole front end and the operating position of target pole front end are different, the initial position of target pole front end is located outside the accelerator yoke, and the operating position of target pole front end is located the interior of accelerator main vacuum chamber, and the distance of these two points leads to the length increase of target pole. Another reason for the increased target shaft length is: the target rod is usually positioned in vacuum, the corrugated pipe is generally arranged outside the target rod, and the corrugated pipe has the effect of pushing the target rod, so that the length of the target rod in the initial state is larger than the length of the target rod which is compressed when the target rod is pushed, the length of the target rod is calculated according to the length of the corrugated pipe in the initial state, and the length of the target rod to be peeled is relatively long due to the two reasons.
Because the target rod is relatively long and needs to swing, when the tail part of the target rod swings in a radial motion mode, the distance from the tail part of the target rod to the front end rotating fulcrum is relatively long, and the moving distance of the tail part of the target rod is relatively large. Taking a certain accelerator as an example, the inner diameter of a corrugated pipe for accommodating the target rod to move therein will reach 340mm, because the inside of the corrugated pipe is vacuum when the device works, the vacuum suction force generated by the outside atmosphere will reach about 10KN, and because the tail part of the corrugated pipe is connected with the tail part assembly, in order to prevent the tail part assembly from being sucked by the vacuum of the corrugated pipe, a corresponding counterweight structure must be added on the mechanical part of the tail part assembly to partially balance the interference force, and the volume and complexity of the whole device can be greatly increased.

2. The invention organically combines all parts, interdependence and mutual support, and achieves the effect of effectively reducing the tail displacement of the target rod after combination. The distance between the initialization position of the front end of the target rod and the working point of the front end of the target rod determines the length of the rear section of corrugated pipe and the length of the front section of corrugated pipe; the diameters of the rear section corrugated pipe and the front section corrugated pipe determine the size of vacuum suction force and determine whether the tail plate assembly needs to be balanced and has a structure; the distance between the point R and the point P on the target rod, namely the distance between the swing vacuum chamber and the radial vacuum chamber, is controlled by the axial position and the peeling angle of the peeling point at the front end of the target rod and the total length of the target rod; the amplitude of the target rod swing is not only limited by the displacement of the peeling point deviating from the initial axis of the target rod, but also limited by the position of the target rod swing axis of the swing vacuum chamber 3 relative to the peeling point. In summary, the individual components support and combine organically, and the effect after combination is much superior to the effect before combination.

Detailed Description

Therefore, the diameter of the corrugated pipe for accommodating the target rod motion is reduced by one half, the diameter of the corrugated pipe is reduced, the vacuum suction force of the corrugated pipe relative to the tail assembly 9 is reduced by one fourth, the space occupied by the tail assembly 9 and the secondary working platform 10 is reduced by one half, the whole equipment is optimized, and the operation reliability is improved. Compared with the two-stage design of fig. 1-2, the whole-stage design of fig. 1-1 has the advantages that the maximum displacement of the point P is increased by one time, the diameter of the bellows accommodating the movement of the target rod is increased by one time, the vacuum suction force of the bellows is increased by three times, the mechanical braking force of the tail plate assembly for overcoming the suction force is increased by three times, and the vacuum suction force overcoming the bellows is not only dependent on the tail plate assembly, but also comprises a moving part connected with the tail plate assembly, such as a secondary working platform, so that the braking force of the secondary working platform also needs additional requirements, or a counterweight needs to be added behind the tail plate assembly or a structure for overcoming the excessive vacuum suction force is added, which can increase the complexity of the equipment and reduce the reliability of the operation;
2) target rod length and related position design principle
a) The total length and the total length of the target rod are determined according to the initial position of the front end of the target rod and the working position of the front end of the target rod, and the lengths of the two sections of corrugated pipes. The front-section corrugated pipe is used for moving the front end of the target rod from an initial position to a stripping point by the secondary working platform 10; the rear section of corrugated pipe is used for moving the target rod hinge 8-3 from the initial position to the position of a radial push-pull device 6-1 of the radial vacuum chamber; b) determining the corresponding swing angle and the axial position when the front end of the target rod covers all stripping points; c) reversely pushing the position of the target rod of the swinging vacuum chamber 3 swinging around the shaft 3-1 and the position of the radial push-pull device 6-1 of the radial vacuum chamber 6 by using the swinging angle and the axial position; d) determining the position of the target bar hinge 8-3; the position of the target bar hinge 8-3 is calculated from two positions: when the target rod is pushed by the tail plate component 9, the target rod hinge 8-3 just reaches the position of the radial push-pull device 6-1, and the front end 8-1 of the target rod also just reaches the position of the stripping point of the main vacuum chamber; e) repeating the above steps according to the position of each peeling point to find the target rod size and the related position of each peeling point

1. the swing of the target rod on the front target rod around the shaft 3-1 and the target rod support sleeve 3-3: in the figure 2-3, the target rod support 3-3 is used for limiting the front target rod to only slide in the inner hole thereof, the target rod support 3-3, the extension pipe around the shaft, the attachment 3-2 and the target rod swing around the shaft 3-1 form a set of rigid components which can only rotate around the shaft by the target rod swing in the horizontal plane, after the front target rod 8-2 is sleeved in the target rod support 3-3, the front target rod 8-2 can only rotate around the shaft 3-1 by the target rod swing and move back and forth in the target rod support 3-3 along with the target rod support 3-3, when the radial push-pull device 6-1 pushes and pulls the target rod hinge 8-3 up and down in the radial direction of the target rod, the front target rod 8-2 is limited to rotate around the shaft 3-1 by taking the target rod swing as the shaft, by controlling the position of the tail plate component 9 relative to the main vacuum chamber, the tail plate assembly 9 controls the hinge 8-5, the rear target rod 8-4, the hinge 8-3 and the tail end of the front target rod 8-2 in turn, thereby limiting the front-back movement position of the front target rod 8-2 in the target rod support sleeve 3-3, and thus the position of the front target rod 8-2 relative to the main vacuum chamber is completely determined.
2. The radial push-pull 6-1 controls the swing amplitude of the target rod. The source of the target rod swing is the radial push-pull 6-1, but not the target rod swing around the shaft 3-1, and the target rod swing around the shaft 3-1 is that the force of the radial push-pull 6-1 is passively applied to the front target rod 8-2 and is transferred to the target rod support 3-3 to rotate: firstly, the radial push-pull device 6-1 acts on the position of a target rod hinge 8-3, the target rod hinge 8-3 transmits force to a front target rod, the front target rod drives a shaft-around extension pipe and an attachment 3-2, the shaft-around extension pipe and the attachment 3-2 are connected with the target rod swing around a shaft 3-1, when the shaft-around extension pipe and the attachment 3-2 swing along with the target rod, the target rod swing around the shaft 3-1 is taken as a shaft to rotate, and therefore the radial push-pull device 6-1 controls the swing amplitude of the target rod finally.
