Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] In fact, the beam receiving device for the end of the proton beam line provided by the present invention is an irradiation experiment device, which is usually set at the end of the proton beam line and used to receive part of the proton beam for irradiation experiments , and at the same time block the redundant proton beam. In order to facilitate the installation of the beam receiving device of the present invention, a counterbore should be provided at the end of the proton beam line in advance.

[0029] Such as figure 1 As shown, a kind of beam receiving device for the proton beam line end provided by the present invention comprises a beam introduction plate 1 for being connected to the coaxial insulating connection of the counterbore hole at the end of the proton beam line, and a beam introduction plate 1 The board 1 is coaxially insulated to a bea...

Abstract

The invention discloses a beam receiving device for the tail end of a proton beam line. The beam receiving device comprises a beam lead-in plate (1) for connecting coaxially with the tail end of the proton beam line in an insulated mode, a beam blocking block (2) coaxially connected with the beam lead-in plate (1) in an insulated mode and a cable; a through hole (11) for beam to enter is formed inthe axial center of the end face of the end, depart form the beam blocking block (2), of the beam lead-in plate (1); a mounting groove (21) communicating with the through hole (11) is formed in the side face, facing the beam lead-in plate (1), of the beam blocking block (2), and a beam receiving plate (3) which is perpendicular to the through hole (10) in the axial direction is fixed in the mounting groove (21); and the cable is connected with the beam receiving plate (3). According to the beam receiving device beam, the beam lead-in plate is directly coaxially connected to the tail end of the proton beam line in an insulated mode, the position of the beam receiving device is limited, the influence of human factors is reduced, the randomness error is effectively avoided, and the accuracyof beam collecting and the success rate of experiments are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cyclotron beam collection, more specifically, it relates to a beam receiving device used at the end of a proton beam line. Background technique [0002] In the irradiation experiment, the collection of the proton beam from the end of the cyclotron proton beam line is an important step in the experiment. The cyclotron accelerates protons, and the beam line outputs high-energy protons. The collection of proton beams directly affects the accuracy of irradiation experiments. [0003] In order to collect the beam accurately, currently in the beam collection of the low-energy cyclotron, the commonly used method is to clamp the component to be irradiated (that is, the component under test) on the servo platform, and use the multi-axis movement of the servo platform To adjust the centering of the tested component and the end structure of the proton beam line, that is, the stepper motor adjusts the position of th...
