Status of the Process Control Systems Upgrade for the Cryogenic Installations of the LHC Based ATLAS and CMS Detectors / Fluder, Czeslaw (CERN) ; Mastyna, Krzysztof (AGH-UST, Cracow) ; Peksa, Pawel (AGH-UST, Cracow) ; Pezzetti, Marco (CERN) ; Tovar González, Antonio (CERN) ; Wolak, Tomasz (AGH-UST, Cracow)
The ATLAS and CMS cryogenic control systems have been operational for more than a decade. Over this period, the number of PLCs faults increased due to equipment ageing, leading to systems failures. [...]
2019 - 5 p. - Published in : 10.18429/JACoW-ICALEPCS2019-WEPHA050
In : 17th Biennial International Conference on Accelerator and Large Experimental Physics Control Systems (ICALEPCS), New York, United States, 5 - 11 Oct 2019, pp.WEPHA050

Automation of the software production process for multiple cryogenic control applications / Fluder, Czeslaw (CERN) ; Lefebvre, Victor (CERN) ; Pezzetti, Marco (CERN) ; Plutecki, Przemyslaw (AGH-UST, Cracow) ; Tovar-González, Antonio (CERN) ; Wolak, Tomasz (AGH-UST, Cracow)
The development of process control systems for the cryogenic infrastructure at CERN is based on an automatic software generation approach. The overall complexity of the systems, their frequent evolution as well as the extensive use of databases, repositories, commercial engineering software and CERN frameworks have led to further efforts towards improving the existing automation based software production methodology. [...]

Improved Software Production for the LHC Tunnel Cryogenics Control System / Fluder, C (CERN) ; Wolak, T (AGH-UST, Cracow) ; Drozd, A (AGH-UST, Cracow) ; Dudek, M (CERN) ; Frassinelli, F (Milan Polytechnic) ; Pezzetti, M (CERN) ; Tovar-Gonzalez, A (CERN) ; Zapolski, M (AGH-UST, Cracow)
The software development for the control system of the cryogenics in the LHC is partially automatized. However, every single modification requires a sequence of consecutive and interdependent tasks to be executed manually by software developers. [...]

Validation of the Data Consolidation in Layout Database for the LHC Tunnel Cryogenics Controls Upgrade / Tovar-Gonzalez, A (CERN) ; Balle, C (CERN) ; Blanco, E (CERN) ; Fortescue-Beck, E (CERN) ; Fluder, C (CERN) ; Inglese, V (CERN) ; Pezzetti, M (CERN) ; Gomes, P (CERN) ; Wolak, T (CERN) ; Dudek, M (CERN) et al.
The control system of the Large Hadron Collider cryogenics manages over 34’000 instrumentation and actuator channels. The complete information on their characteristics and parameters can be extracted from a set of views on the Layout database, to generate the specifications of the control system; from these, the code to populate PLCs (Programmable Logic Controller) and SCADA (Supervisory Control & Data Acquisition) is automatically produced, within the UNICOS framework (Unified Industrial Control System).

The Control System for the Cryogenics in the LHC Tunnel / Gomes, P (CERN) ; Anastasopoulos, K (Natl. Tech. U., Athens) ; Antoniotti, F (CERN) ; Avramidou, R (Natl. Tech. U., Athens) ; Balle, Ch (CERN) ; Blanco-Viñuela, E (CERN) ; Carminati, Ch (CERN) ; Casas-Cubillos, J (CERN) ; Ciechanowski, M (AGH-UST, Cracow) ; Dragoneas, A (Natl. Tech. U., Athens) et al.
The Large Hadron Collider makes extensive use of superconductors, in magnets for bending and focusing the particles, and in RF cavities for accelerating them, which are operated at 1.9 K and 4.5 K. The process automation for the cryogenic distribution around the accelerator circumference is based on 16 Programmable Logic Controllers, each running 250 control loops, 500 alarms and interlocks, and a phase sequencer.
