CERN Cryogenic Controls Today and Tomorrow / Pezzetti, Marco (CERN) ; Gayet, Philippe (CERN)
The CERN cryogenic facilities demand a versatile, distributed, homogeneous and highly reliable control system. For this purpose, CERN conceived and developed several frameworks (JCOP, UNICOS, FESA, CMW), based on current industrial technologies and COTS equipment, such as PC, PLC and SCADA systems complying with the requested constraints. [...]

LHC magnet quench detection by trend analysis of the pressure signal / Charbonnier, Sylvie (Grenoble, INP) ; Rijllart, Adriaan (CERN) ; Gayet, Philippe (CERN)
CERN's LHC is composed of thousands of superconductor magnets that may sometimes quench (lose suddenly their superconducting properties). This paper presents a method to detect magnet quenches from the pressure of the helium inside the magnets. [...]

Online analysis for anticipated failure diagnostics of the CERN cryogenic systems / Gayet, Philippe (CERN) ; Blanco Viñuela, Enrique (CERN) ; Bradu, Benjamin (CERN) ; Cirillo, Roberta (CERN)
The cryogenic system is one of the most critical component of the CERN Large Hadron Collider (LHC) and its associated experiments ATLAS and CMS. In the past years, the cryogenic team has improved the maintenance plan and the operation procedures and achieved a very high reliability. [...]

Fault template extraction to assist operators during industrial alarm floods / Charbonnier, Sylvie (U. Grenoble Alpes) ; Bouchair, Nabil (CERN) ; Gayet, Philippe (CERN)
In industrial systems, a fault occurring on a process can create an alarm flood, a succession of alarms raised at a rate per minute so high it overwhelms the process operator in charge of the monitoring of the process. In this paper, a method to extract fault templates from a set of alarm lists raised on the occurrence of several faults is proposed. [...]

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. [...]

TIP: An Umbrella Application for all SCADA-Based Applications for the CERN Technical Infrastructure / Varela, Fernando (CERN) ; Gayet, Philippe (CERN) ; Golonka, Piotr (CERN) ; Gonzalez-Berges, Manuel (CERN) ; Goralczyk, Lukasz (AGH-UST, Cracow) ; Pache, Julien (CERN) ; Sollander, Peter (CERN)
The WinCC Open Architecture (OA) SCADA package and the controls frameworks (UNICOS, JCOP) developed at CERN were successfully used to implement many critical control systems at CERN. In the recent years, the supervision and the controls of many technical infrastructure systems (electrical distribution, cooling and ventilation, etc.) were rewritten to use this standard environment.

Example of cryogenic process simulation using EcosimPro: LHC beam screen cooling circuits / Bradu, Benjamin (CERN) ; Blanco Vinuela, Enrique (CERN) ; Gayet, Philippe (CERN)
CERN has developed a dedicated library to model helium cryogenic plants with a commercial software called EcosimPro. The aim of such a library is to provide a simple way to model small and large scale cryogenic systems performing dynamic simulations in an acceptable timescale to assist both control and operation teams in the optimal commissioning and operation of cryogenic plants.

A process and control simulator for large scale cryogenic plants / Bradu, Benjamin (CERN ; Laboratoire des Signaux et Systèmes, Gif-sur-Yvette) ; Gayet, Philippe (CERN) ; Niculescu, Silviu-Iulian (Laboratoire des Signaux et Systèmes, Gif-sur-Yvette)
This paper presents a process and control simulator for industrial helium cryogenic plants controlled by Programmable Logic Controllers (PLC). This simulator can be used for different purposes such as operator training, test of the PLC programs or the optimization of the plant. [...]
