/ 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. [...]

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.

The Upgrade of Control Hardware of the CERN NA62 Beam Vacuum
/ Mateo, Fernando (CERN) ; Antoniotti, Fabien (CERN) ; Blanchard, Sebastien (CERN) ; Ferreira, Rodrigo (CERN) ; Gomes, Paulo (CERN) ; Gutierrez, Abel (CERN) ; Jenninger, Berthold (CERN) ; Pereira, Helder (CERN)
NA62 is the follow-up of the NA48 experiment, in the SPS North Area of CERN, and reuses a large fraction of its detectors and beam line equipment. Still, there are many new vacuum devices in the beam line (including pumps, valves & gauges), which required a thorough modification of the control system and a large number of new controllers, many of which were custom-made. [...]

Scalable Web Broadcasting for Historical Industrial Control Data
/ Copy, Brice (CERN) ; Andreassen, Odd (CERN) ; Gayet, Philippe (CERN) ; Labrenz, Mirjam (CERN) ; Milcent, Herve (CERN) ; Piccinelli, Flavio (CERN)
With the wide-spread use of asynchronous web communication mechanisms like WebSockets and WebRTC, it has now become possible to distribute industrial controls data originated in field devices or SCADA software in a scalable and event-based manner to a large number of web clients in the form of rich interactive visualizations. There is however no simple, secure and performant way yet to query large amounts of aggregated historical data. [...]
