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).

Unified Software Production Process for CERN Cryogenic Control Applications
/ Pezzetti, Marco (CERN) ; Barbe, Thomas (CERN) ; Fluder, Czeslaw (CERN) ; Kubla, Tomas (CERN) ; Rog, Sebastian (AGH-UST, Cracow) ; Tovar-Gonzalez, Antonio (CERN)
The software engineering of process control system for CERN cryogenic installations is based on an automatic code production methodology and continuous integration practice. This solution was initially developed for the LHC Accelerator applications, then adapted to LHC Detectors, test facilities and non-LHC cryogenic facilities. [...]

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.

First Assessment of Reliability Data for the LHC Accelerator and Detector Cryogenic System Components
/ Perinic, G (CERN) ; Claudet, S (CERN) ; Alonso-Canella, I (CERN) ; Balle, C (CERN) ; Barth, K (CERN) ; Bel, J F (CERN) ; Benda, V (CERN) ; Bremer, J (CERN) ; Brodzinski, K (CERN) ; Casas-Cubillos, J (CERN) et al.
The Large Hadron Collider (LHC) cryogenic system comprises eight independent refrigeration and distribution systems that supply the eight 3.3 km long accelerator sectors with cryogenic refrigeration power as well as four refrigeration systems for the needs of the detectors ATLAS and CMS. In order to ensure the highest possible reliability of the installations, it is important to apply a reliability centred approach for the maintenance. [...]
