/ Cardin, Chloe (CERN) ; Galilée, Marc-Antoine (CERN) ; Garnier, Jean-Christophe (CERN) ; Krol, Kamil (CERN) ; Osinski, Maciej (CERN) ; Stanisz, Anita (CERN) ; Zerlauth, Markus (CERN)
Today's front-end controllers, which are widely used in CERNs controls environment, feature CPUs with high clock frequencies and extensive memory storage. Their specifications are comparable to low-end servers, or even smartphones. [...]

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.

Second Generation LHC Analysis Framework: Workload-based and User-oriented Solution
/ Boychenko, Serhiy (CERN) ; Aguilera-Padilla, Cesar (CERN) ; Galilée, Marc-Antoine (CERN) ; Garnier, Jean-Christophe (CERN) ; Gorzawski, Arkadiusz (CERN) ; Krol, Kamil (CERN) ; Makai, Jozsef (CERN) ; Osinski, Maciej (CERN) ; Poeschl, Matthias (CERN) ; Rela, Mario (Coimbra U.) et al.
Consolidation and upgrades of accelerator equipment during the first long LHC shutdown period enabled particle collisions at energy levels almost twice higher compared to the first operational phase. Consequently, the software infrastructure providing vital information for machine operation and its optimisation needs to be updated to keep up with the challenges imposed by the increasing amount of collected data and the complexity of analysis.

A Generic Real-Time Software in C++ for Digital Camera-Based Acquisition Systems at CERN
/ Topaloudis, Athanasios (CERN) ; Bravin, Enrico (CERN) ; Burger, Stephane (CERN) ; Jackson, Stephen (CERN) ; Mazzoni, Stefano (CERN) ; Poimenidou, Eirini (CERN) ; Senes, Eugenio (CERN)
Until recently, most of CERN’s beam visualisation systems have been based on increasingly obsolescent analogue cameras. Hence, there is an on-going campaign to replace old or install new digital equivalents. [...]

Reusable Real-Time Software Components for the SPS Low Level RF Control System
/ Sumiński, Maciej (CERN) ; Adrianek, Karol (CERN) ; Bielawski, Bartosz Przemyslaw (CERN) ; Butterworth, Andrew (CERN) ; Egli, Julien (CERN) ; Hagmann, Gregoire (CERN) ; Kuzmanović, Predrag (CERN) ; Novel González, Saul (CERN) ; Rey, Anthony (CERN) ; Spierer, Arthur (CERN)
In 2021 the Super Proton Synchrotron has been recommissioned after a complete renovation of its low level RF system (LLRF). The new system has largely moved to digital signal processing implemented as a set of functional blocks (IP cores) in Field Programmable Gate Arrays (FPGAs) with associated software to control them.

Testing Framework for the LHC Beam-based Feedback System
/ Jackson, Stephen (CERN) ; Alves, Diogo (CERN) ; Di Giulio, Letizia (CERN) ; Fuchsberger, Kajetan (CERN) ; Kolad, Blazej (CERN) ; Pedersen, Jens (CERN)
During the first LHC shut-down period, software for the LHC Beam-based Feedback Controller (BFC) and Service Unit (BFSU) was migrated to new 64-bit multi-core hardware and to a new version of CERN's FESA3 real-time framework. This coincided with the transfer of responsibility to a new software team, charged with readying the systems for beam in 2015 as well as maintaining and improving the code-base in the future. [...]

A Modernized Architecture for the Post Mortem System at CERN
/ Barth, Jonas (CERN) ; Bogyai, Filip (CERN) ; Garnier, Jean-Christophe (CERN) ; Majewski, Marcin (CERN) ; Martins Ribeiro, Tiago (CERN) ; Mnich, Aleksandra (CERN) ; Pocwierz, Maciej (CERN) ; Selvek, Robert (CERN) ; Simpson, Robert (CERN) ; Stanisz, Anita (CERN) et al.
The control system of the accelerators at CERN stores and analyzes more than 200 million dumps of high resolution data recordings every year in the Post Mortem (PM) system. A continuous increase in the complexity of the Large Hadron Collider’s (LHC) systems and the desire to collect more accurate data requires continuous improvement of the PM system. [...]

SoC Technology for Embedded Control and Interlocking Within Fast Pulsed Systems at CERN
/ Van Trappen, Pieter (CERN) ; Carlier, Etienne (CERN) ; Gauthier, Maxime (CERN) ; Magnin, Nicolas (CERN) ; Oltedal, Eino Juhani (CERN) ; Schipper, Jan (CERN)
The control of pulsed systems at CERN requires often the use of fast digital electronics to perform tight timing control and fast protection of high-voltage pulsed generators. For the implementation of such functionalities, a FPGA is the perfect candidate for the digital logic, however with limited integration potential within the control system. [...]
