Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, the present invention provides a vacuum environment beam energy online adjustment device, including a de-energized vacuum chamber 1, a driving component and a de-energized adjustment assembly; the de-energized vacuum chamber 1 is provided with a beam pipeline; The energy-adjusting assembly is connected with the driving part, including two energy-reducing sheets that cooperate with each other; the energy-reducing sheets can be overlapped in the described energy-reducing vacuum chamber 1 to change the energy-reducing thickness so as to adjust the beam energy (see figure 2 with Figure 4 ). The de-energy vacuum chamber 1 is provided with a pumping port 3 . The sealing flange of the de-energizing adjustment assembly is connected to the de-energizing vacuum chamber 1 through a bellows; the bellows can expand and contra...

Abstract

The invention relates to a vacuum environment beam energy online adjusting device which comprises an energy reduction vacuum chamber, a driving part and an energy reduction adjusting assembly. A beamcurrent pipeline is arranged on the energy-reducing vacuum chamber, the energy reduction adjusting assembly is connected with the driving part and comprises two energy reduction sheets which are matched with each other, and the energy-reducing sheets can be overlapped in the energy-reducing vacuum chamber to change the energy-reducing thickness so as to adjust the beam energy. The vacuum environment beam energy online adjusting device has the following beneficial effects that the beam energy of a particle accelerator can be adjusted on line by continuously adjusting the thicknesses of the energy-reducing sheets at the beam, the energy adjustment can be continuous, the adjustment range is large, the adjustment precision is high, and the structural design is simple; and the shape of the energy-reducing sheet is designed into a right triangle, and by adopting the installation manner that the hypotenuses of the two right triangles are opposite, the beam scattering is effectively reduced.

Description

technical field [0001] The invention belongs to the field of particle accelerators, and in particular relates to an online adjustment device for beam energy in a vacuum environment. Background technique [0002] At present, the application of beam terminals puts forward higher requirements on beam energy and quality. The most prominent room is aimed at the fields of aerospace satellite space electron irradiation effects, space electronic environment simulation, and nuclear technology applications. The beam energy requirements can be adjusted. It is difficult to adjust the source itself to meet the needs of scientific research. In the field of particle accelerators, especially electron linear accelerators, it is a passive energy adjustment device realized by the principle of energy loss due to the interaction between particles and matter. The core of this beam energy adjustment device is that when a beam of specific energy passes through material blocks of different thickness...
