Ground vibration monitoring at CERN as part of the international seismic network / Charrondiere, Cedric (CERN) ; Cabon, Morgane (CERN) ; Develle, Kevin (CERN) ; Guinchard, Michael (CERN)
The civil engineering activities in the framework of the High Luminosity LHC project, the Geneva GEothermie 2020 and the continuous monitoring of the LHC civil infrastructures triggered the need for the installation of a seismic network at CERN. A data acquisition system has been deployed in 3 places at CERN: ATLAS, CMS and the Prévessin site. [...]

Synchronizing LabVIEW Development and Deployment Environment / Andreassen, Odd (CERN) ; Charrondière, Cedric (CERN) ; Miskowiec, Martyna (CERN) ; Reymond, Hubert (CERN) ; Rijllart, Adriaan (CERN)
LabVIEW with its graphical approach is suited for engineers used to design and implement systems based on schematics and designs. Being a graphical language, it can be challenging to keep track of drivers, runtime engines, deployments and configurations since most of the tools on the market aimed towards this are implemented for textual languages. [...]

Lessons Learned Moving from Pharlap to Linux RT / Charrondière, Cedric (CERN) ; Andreassen, Odd (CERN) ; Sierra-Maíllo Martínez, Diego (CERN) ; Tagg, Joseph (CERN) ; Zilliox, Thomas (CERN)
The start of the Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) facility at CERN in 2016 came with the need for a continuous image acquisition system. The international scientific collaboration responsible for this project requested low and high resolution acquisition at a capture rate of 10Hz and 1 Hz respectively. [...]
