Wire array structure and measuring device of high resolution wire array type beam cross section measuring device

Abstract

The invention relates to a wire array structure of a high-resolution wire array type beam section measurement device and a measurement device comprising the wire array structure. The invention solvesthe problem in the prior art that in an existing wire array type beam section measurement device, a detection wire is too tightened to be easily broken, or the perpendicularity and the parallelism cannot be kept when the detection wire is not tightened enough can be solved. Meanwhile, the problems that when the detection wire is bombarded by a beam current, the detection wire is heated and deformed, and the process difficulty is increased due to tight arrangement of a plurality of detection wires when the envelop of the beam current is small enough can also be solved. The wire array structureadopted by the device comprises a detection wire, a first tightened spring, a first insulation adjusting block and a second insulation adjusting block. One end of the detection wire is connected withthe first insulation adjusting block through the first tightened spring, and the other end of the detection wire is connected with the second insulation adjusting block. The detection wire can be automatically adjusted and is not easy to break. Meanwhile, cross-section density measurement results in the X direction and in the Y direction can be given in real time. The device is high in measurement resolution, small in influence on beam current, convenient in signal processing, simple and reliable in structure and fast in measurement speed.

Description

technical field [0001] The invention belongs to the technical field of particle accelerators, and in particular relates to a wire array structure of a high-resolution wire array type beam cross section measuring device and a measuring device including the wire array structure. Background technique [0002] The beam cross-section is an important parameter of the beam. The measurement of the beam cross-section can not only intuitively give the center position, beam envelope and lateral uniformity distribution of the beam, but also combine the quadrupole iron scanning and other methods to give the beam current The emissivity of the accelerator is critical for debugging the accelerator and end-user experimentation. [0003] In the field of beam cross-section measurement of low-energy proton beams, there are mainly methods based on optics, methods based on wire scanning and methods based on wire arrays. [0004] Among them, the optical-based method is the most commonly used fluo...
