Renovation of the Control System of a High-Pressure Water Rinsing Machine for Superconducting RF Cavities using the UNICOS-CPC Framework / Staniszewska, Joanna (CERN) ; Ferreira, Rodrigo (CERN) ; Pigny, Gregory (CERN)
It is often the case that the control systems in industrial facilities remain in operation for many years without maintenance and updates. As manufacturers introduce new hardware and software solutions, it becomes difficult to find spare parts and technical support for legacy technologies. [...]

Vacuum Controls Configurator: A Web Based Configuration Tool for Large Scale Vacuum Control Systems / Rocha, Andre (CERN) ; Amador, Ivo (CERN) ; Blanchard, Sebastien (CERN) ; Fraga, Jorge (CERN) ; Gomes, Paulo (CERN) ; Lima, Christopher (CERN) ; Pigny, Gregory (CERN) ; Poulopoulou, Panagiota (CERN)
The Vacuum Controls Configurator (vacCC) is an application developed at CERN for the management of large-scale vacuum control systems. The application was developed to facilitate the management of the configuration of the vacuum control system at CERN, the largest vacuum system in operation in the world, with over 15,000 vacuum devices spread over 128 km of vacuum chambers. [...]

Radiation tolerant conditioning electronics for vacuum measurements / Chatzigeorgiou, Nikolaos ; Pigny, Gregory ; Krakowski, Pawel Wojciech
Vacuum in the arcs of the LHC is crucial to minimize beam – gas interactions and to assure thermal insulation of cryostats and helium distribution lines. Several hundred of sensors with their associated conditioning electronics are installed across the arcs for both beam and insulation vacuum measurements. [...]

LTE/3G-based wireless communications for remote control and monitoring of PLC-controlled mobile vacuum devices / Ferreira, Rodrigo (CERN) ; Blanchard, Sebastien (CERN) ; Fernandes, Telmo (Leiria, IPL) ; Gomes, Paulo (CERN) ; Pigny, Gregory (CERN)
All particle accelerators and most experiments at CERN require high (HV) or ultra-high (UHV) vacuum levels. Contributing to vacuum production are two types of mobile devices: Turbo-Molecular Pumping Groups and Bakeout Racks. [...]
