Abstract

The invention relates to an accelerator beam position diagnosis system and an accelerator beam position diagnosis method based on eight-octant probe distribution. The system comprises a three-dimensional eight-octant interception-type probe distribution mechanism, a multi-range passive filter signal conditioning module, a beam signal amplifying module, a beam signal photoelectric isolation module, a beam signal acquisition module, a beam position automatic diagnosis module and an intelligent configuration decision supporting system. When a particle accelerator operates, the eight-octant probes distributed on the wall of a vacuum pipeline collect beam signals coupled by charges incident to the sensitive ends by the beam, the position automatic diagnosis module in the controller calculates the position information of the beam in real time according to eight-octant voltage signals acquired by the signal acquisition module, the operation result is transmitted to the intelligent configuration decision supporting system of an operation station, a three-dimensional animation is adopted to prompt the operator whether the beam biases and the beam adjustment strategy. Through the intelligent and visual diagnosis strategy, the accuracy, the real-time performance and the usability of the accelerator beam position measurement system are effectively improved.
