Abstract:
CERN is an International Organization whose chief goal is to perform fundamental particle physics research. The main tool used for such research is a complex network of particle accelerators and detectors with very demanding requirements for vacuum levels in the beam pipes, detectors, and cryogenic insulation elements. Vacuum is partly assured by turbo-molecular pumping groups (VPG), which are for the most part PLC controlled. This paper briefly introduces the CERN accelerator complex and its vacuum installation; it then focuses on the different control architectures used for VPGs and the types of controllers employed, identifying the shortcomings that arise from having multiple models in operation. The final aim is to converge into a unified control solution to be used in most situations, with limited variations, simplifying maintenance and new deployments over the next decades.
