Big Data Archiving From Oracle to Hadoop / Prieto Barreiro, Ivan (CERN) ; Sobieszek, Marcin (CERN)
The CERN Accelerator Logging Service (CALS) is used to persist data of around 2 million predefined signals coming from heterogeneous sources such as the electricity infrastructure, industrial controls like cryogenics and vacuum, or beam related data. This old Oracle based logging system will be phased out at the end of the LHC’s Long Shut-down 2 (LS2) and will be replaced by the Next CERN Accelerator Logging Service (NXCALS) which is based on Hadoop. [...]

CERN Controls Configuration Service - a challenge in usability / Burdzanowski, Lukasz (CERN) ; Asko, Anti (CERN) ; Lameiro Fernandes, Ana (CERN) ; Penar, Katarzyna (CERN) ; Roderick, Chris (CERN) ; Urbaniec, Bartlomiej (CERN) ; Vasiloudis, Vasileios Ioulios (CERN)
Complex control systems often require complex tools to facilitate daily operations in a way that assures the highest possible availability. Such a situation poses an engineering challenge, for which system complexity needs to be tamed in a way that everyday use becomes intuitive and efficient. [...]

Quench detection and diagnostic systems for the superconducting circuits for the HL-LHC / Denz, Reiner (CERN) ; Blasco Serrano, Daniel (Madrid, CIEMAT ; CERN) ; Calcoen, Daniel (CERN) ; De Matteis, Ernesto (CERN) ; Froidbise, Vincent (CERN) ; Georgakakis, Spyridon (CERN) ; Haas, Severin (CERN) ; Mundra, Surbhi (CERN) ; Podzorny, Tomasz (CERN) ; Siemko, Andrzej (CERN) et al.
The High Luminosity Upgrade of the LHC [1] will incorporate a new generation of superconducting elements such as high field superconducting magnets based on Nb$_3$Sn conductors and MgB$_2$ high temperature superconducting links for magnet powering. The proper protection and diagnostics of those elements require the development of a new generation of integrated quench detection and data acquisition systems as well as novel methods for quench detection.
