Cosmology and Dark Matter / Tkachev, Igor (Moscow, INR)
This lecture course covers cosmology from the particle physicist perspective. Therefore, the emphasis will be on the evidence for the new physics in cosmological and astrophysical data together with minimal theoretical frameworks needed to understand and appreciate the evidence. [...]

Renovation and extension of supervision software leveraging reactive streams / Galilée, Marc-Antoine (CERN) ; Calia, Andrea (CERN) ; Do, Janet (CERN) ; Fuchsberger, Kajetan (CERN) ; Garnier, Jean-Christophe (CERN) ; Krol, Kamil (CERN) ; Osinski, Maciej (CERN) ; Pocwierz, Maciej (CERN) ; Ribeiro, Tiago (CERN) ; Stanisz, Anita (CERN) et al.
Inspired by the recent developments of reactive programming and the ubiquity of the concept of streams in modern software industry, we assess the relevance of a reactive streams solution in the context of accelerator controls. The promise of reactive streams, to govern the exchange of data across asynchronous boundaries at a rate sustainable for both the sender and the receiver, is alluring to most data-centric processes of CERN's accelerators.

MARS: Easing maintenance and interventions for CERN controls / Varela, Fernando (CERN) ; Epting, Uwe (CERN) ; Gonzalez Corral, Montserrat (CERN) ; Mandilara, Eleni (CERN) ; Podgorski, Stanislaw (CERN)
Industrial control systems for the CERN technical infrastructure and accelerator complex consist of a myriad of devices and components geographically distributed around the CERN facilities. In the event of an intervention in such systems, the on-call engineer or the system expert needs detailed information about the nature of the problem, e.g. [...]

Introducing fast interlocks in the UNICOS-CPC framework / Ortola Vidal, Jeronimo (CERN) ; Blanco Viñuela, Enrique (CERN) ; Vazquez Muñiz, Manuel (CERN)
The CERN UNified Industrial COntrol System framework (UNICOS) with its Continuous Control Package (UNICOS-CPC) is the CERN standard solution for the design and implementation of continuous industrial process control applications. The need of adapting the framework capabilities to the different processes at CERN has brought new challenges. [...]

Integration of PLC and PXI control systems / Antoine, Alain (CERN) ; Boucly, Christophe (CERN) ; Gharsa, Thierry (CERN)
Engineers are often challenged with the need to integrate several technologies to find optimal solutions when designing new control architectures. Generally, the technical solutions chosen require the combination of various industrial products such as PXI systems for applications requiring fast acquisition, analysis and reaction times, while PLCs are commonly used for their reliability and their ability to withstand industrial environments.

Wall current monitor using PXI and LabVIEW at CERN / Charrondiere, Cedric (CERN) ; Delrieux, Marc (CERN) ; Limpens, Rik (CERN)
The new data acquisition system for the PS ring wall current monitors installed in the PS is able to perform high frequency measurements of a beam bunch up to a frequency of 2.7 GHz. This is an important improvement, since the oscillating signal within the bandwidth 500-700 MHz, is related to losses of a beam bunch. [...]

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. [...]

Integration of personal protective equipment checks in access control / Pok, Peter (CERN) ; Havart, Frederic (CERN) ; Ladzinski, Tomasz (CERN)
Access to the interlocked zones of the CERN accelerator complex is allowed only for personnel wearing standard personal protective equipment. This equipment is complemented by specialised personal protective devices in case of specific hazards related to the remnant radiation or the presence of cryogenic fluids. [...]
