The Research of Multi-Station High-Precision Rotary Motion of CSNS Stripper Foil System

摘要

Multi-station rotary structure is used in the China Spallation Neutron Source (CSNS) stripper foil. The repeat positioning accuracy of per foil frame is more than 0.5mm, which do not meet the technical requirements, due to the rotary membrane structure and the frame accuracy. This paper researches for the multi-axis synchronous system to control the rotary membrane and achieve the repeat positioning accuracy to be better than ±0.05mm. This paper also researches on the remote control system based on the EPICS and realize the remote control of stripper foil system.
