Operational Controls for Robots Integrated in Accelerator Complexes / Fargier, Sylvain (CERN) ; Di Castro, Mario (CERN) ; Donzé, Mathieu (CERN)
The fourth industrial revolution, the current trend of automation and data interconnection in industrial technologies, is becoming an essential tool to boost maintenance and availability for space applications, warehouse logistics, particle accelerators and for harsh environments in general. The main pillars of Industry 4.0 are Internet of Things (IoT), Wireless Sensors, Cloud Computing, Artificial Intelligence (AI), Machine Learning and Robotics. [...]

Early Fire Detection in High Power Equipment / Pavis, Steven (CERN) ; Carlier, Etienne (CERN) ; Lolliot, Christophe (CERN) ; Magnin, Nicolas (CERN)
Very early fire detection in equipment cabinets containing high power supply sources and power electronic switching devices is needed when building and tunnel fire detection systems may not be well placed to detect a fire until it is well established. Highly sensitive aspirating smoke detection systems which continuously sample the air quality inside equipment racks and give local power interlock in the event of smoke detection, are capable of cutting the source of power to these circuits at a very early stage, thereby preventing fires before they become fully established.

Porting OpenMMC to STM32 Microcontrollers for Flexible AMC Development / Stubbings, Michael (Diamond Light Source) ; Perez Juarez, Emilio (Diamond Light Source) ; Stant, Laurence (Diamond Light Source) ; Wujek, Adam (CERN)
Diamond Light Source has chosen the MicroTCA platform for high performance data acquisition and controls as part of the Diamond-II 4th generation light source upgrade. One requirement is the ability to create custom advanced mezzanine cards (AMCs) for signal conditioning and interlock support. [...]

Energy Consumption Optimisation by Using Advanced Control Algorithms / Ghawash, Faiq (CERN ; Norwegian U. Sci. Tech.) ; Blanco Viñuela, Enrique (CERN) ; Schofield, Brad (CERN)
Large industries operate energy-intensive equipment and energy efficiency is an important objective when trying to optimize the final energy consumption. CERN utilizes a large amount of electrical energy to run its accelerators, detectors and test facilities, with a total yearly consumption of 1.3 TWh and peaks of about 200 MW. [...]

A Modular Approach for Accelerator Controls Components Deployment for High Power Pulsed Systems / Pavis, Steven (CERN) ; Barlow, Roger (CERN) ; Boucly, Christophe (CERN) ; Carlier, Etienne (CERN) ; Chanavat, Christophe (CERN) ; Lolliot, Christophe (CERN) ; Magnin, Nicolas (CERN) ; Van Trappen, Pieter (CERN) ; Voumard, Nicolas (CERN)
As part of the LHC Injector Upgrade (LIU) project, the controls of the PSB and PS injection kickers at CERN have been upgraded during Long Shutdown 2 (LS2) from heterogeneous home-made electronic solutions to a modular and open architecture. Despite both kickers have significantly different functionalities, topologies and operational requirements, standardized hardware and software control blocks have been used for both systems. [...]

The Micro-Services of Cern’s Critical Current Test Benches / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Boutboul, Thierry (CERN) ; Fleiter, Jerome (CERN) ; Hopkins, Simon (CERN) ; Koziol, Piotr (CERN) ; Reymond, Hubert (CERN)
In order to characterize the critical-current density of low temperature superconductors such as niobium¿titanium (NbTi) and niobium¿tin (Nb₃Sn) or high temperature superconductors such as magnesium-diboride MgB₂ or Rare-earth Barium Copper Oxide REBCO tapes, a wide range of custom instruments and interfaces are used. The critical current of a superconductor depends on temperature, magnetic field, current and strain, requiring high precision measurements in the nano Volt range, well-synchronized instrumentation, and the possibility to quickly adapt and replace instrumentation if needed.
