Abstract

The invention discloses an accelerator beam cross section measurement system based on LabVIEW. The accelerator beam cross section measurement system comprises a fluorescent target, an observation window, a transmission system, a grating ruler and an electronics processing module thereof, a camera, a switch and an upper computer; the transmission system comprises a transmission rod, a transmission mechanism, a servo motor, a servo motor driver and a motion controller; the fluorescent target and the camera are driven by the transmission system to do linear motion; the camera is connected with the switch through a network cable, and the switch is connected with the upper computer through the network cable again; real-time position information of the fluorescent target is obtained by adopting the grating ruler and then converted into a network signal by using the electronics processing module of the grating ruler, and the network signal is transmitted to the upper computer for processing. The invention further discloses an accelerator beam cross section measurement method based on LabVIEW. The accelerator beam cross section measurement system disclosed by the invention has the advantages of being high in signal bandwidth, good in real time and high in stability, the measurement accuracies of the cross section size and the position of a beam reach 0.1 millimeter respectively, and the image transmission distance reaches 100 meters.

Description

technical field

[0001] The invention belongs to the technical field of accelerator beam current diagnosis, in particular to a LabVIEW-based accelerator beam section measurement system and method. Background technique

[0002] LabVIEW is a program development environment developed by National Instruments (NI), similar to C and BASIC development environments, but the significant difference between LabVIEW and other computer languages ​​is that other computer languages ​​use text-based language to generate code , while LabVIEW uses the graphical editing language G to write the program, and the generated program is in the form of a block diagram. LabVIEW software is at the heart of the NI design platform and is ideal for developing measurement or control systems.

[0003] For particle accelerators, the beam cluster transverse section size and horizontal and vertical positions are important basic parameters, which are an important diagnostic tool for studying beam instability, a...
