Abstract
The utility model discloses a guiding controller for regulating the size of electronic beams. The guiding controller comprises an accelerating tube, a scanning box connected to the lower end of the accelerating tube, a guiding coil which adjusts beam offset and is installed on the accelerating tube, and a diaphragm plate arranged at the joint between the accelerating tube and the scanning box. A circular hole is arranged on the center of the diaphragm plate. The guiding controller solves the problem that the size of electron beams in microampere level is difficult to regulate. Since the diaphragm plate with a circular hole on the center is added between the accelerating tube and the scanning box, the size of electronic beams can be controlled by controlling the current of a guiding coil to adjust the beam flow passing through the circular hole. The guiding controller is simple in structure, convenient for operation, and great in adjusting range, and can conveniently reduce the beam by two orders of magnitude.
Description
Technical field
The utility model has related to a kind of guide control device of electronic beam current size, belongs to accelerator line control technology field.
Background technology
At present, both at home and abroad the minimum work line of accelerator is all at the milliampere order of magnitude, and usually is operated in fixedly under the line.Same accelerator when different occasions work, the line adjustable extent also in an order of magnitude, as to be adjusted to stably, reposefully tens microamperes with interior almost be impossible realize.
By the improvement of filament, it is steadily adjustable that line is realized in the microampere order of magnitude, but will receive in the amperage magnitude steadily adjustable can't the realization.
The utility model content
Technical problem to be solved in the utility model provides a kind of guide control device of electronic beam current size, by changing the size of current of guidance coil, regulates the line amount of line by circular hole, thereby realizes the control to the electronic beam current size.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of guide control device of electronic beam current size, comprise accelerating tube, the lower end of described accelerating tube is connected with scan box, the guidance coil that is used to adjust the beam excursion amount is installed on the described accelerating tube, the junction of described accelerating tube and scan box is provided with aperture plate, and the center of described aperture plate has circular hole.
The guide control device of aforesaid electronic beam current size is characterized in that: be hollow form around the described aperture plate edge, and be provided with the limbers.
The guide control device of aforesaid electronic beam current size is characterized in that: the accelerating tube of described guidance coil top is provided with focusing coil.
The guide control device of aforesaid electronic beam current size is characterized in that: the top of described scan box is provided with Y scanning yoke and X scanning yoke.
The beneficial effects of the utility model are: by install an aperture plate additional between the scan box of original device and accelerating tube, and open a circular hole in the center of aperture plate, pass through the line amount of circular hole by the Current Regulation electronic beam current of control guidance coil, thereby realized control to the electronic beam current size, this apparatus structure is simple, easy to operate, and the amplitude of accommodation is big, can easily line be reduced by 2 orders of magnitude.
Description of drawings

Embodiment
Below in conjunction with Figure of description, the utility model is described further.
As shown in Figure 1, a kind of guide control device of electronic beam current size, comprise accelerating tube 1, the lower end of described accelerating tube 1 is connected with scan box 7, the guidance coil 3 that is used to adjust the beam excursion amount is installed on the described accelerating tube 1, described accelerating tube 1 is provided with aperture plate 4 with the junction of scan box 7, and the center of described aperture plate 4 has circular hole 41.By between the scan box 7 of original device and accelerating tube 1, installing an aperture plate 4 additional, and open a circular hole 41 in the center of aperture plate 4, pass through the line amount of circular hole 41 by the Current Regulation electronic beam current of control guidance coil 3, thereby realized control to the electronic beam current size, the size of described circular hole 41 is for allowing about 70% line smoothly by being advisable, and the edge of line is blocked, absorbs by aperture plate 4.
Around described aperture plate 4 edges is hollow form, and is provided with limbers 42, adds water by limbers 42 in aperture plate 4, so that the heat that the electron beam that cooling is blocked is sent out is avoided temperature rise.
The accelerating tube 1 of described guidance coil 3 tops is provided with focusing coil 2, and the top of described scan box is provided with Y scanning yoke 5 and X scanning yoke 6.
The guide control device of a kind of electronic beam current size that the utility model provides by changing the size of current of guidance coil, is regulated the line amount of line by circular hole, thereby realizes the control to the electronic beam current size.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
