CERN SPS Dilution Kicker Vacuum Pressure Behaviour under Unprecedented Beam Brightness / Velotti, Francesco (CERN) ; Barnes, Michael (CERN) ; Bartmann, Wolfgang (CERN) ; Bartosik, Hannes (CERN) ; Carlier, Etienne (CERN) ; Favia, Giorgia (CERN) ; Karpov, Ivan (CERN) ; Li, Kevin (CERN) ; Magnin, Nicolas (CERN) ; Mether, Lotta (CERN) et al.
The Super Proton Synchrotron (SPS) is the second largest synchrotron at CERN and produces high-brightness beams for the Large Hadron Collider (LHC). Recently, the dilution kicker (MKDH) of the SPS beam dump system (SBDS) has demonstrated unanticipated behaviour under high beam brightness conditions. [...]

SPS Beam Dump Enhancements on Tracking and Synchronization / Voumard, Nicolas (CERN) ; Magnin, Nicolas (CERN) ; Van Trappen, Pieter (CERN)
During Long Shutdown 2 (LS2) at CERN, the SPS Beam Dumping System (SBDS) was completely renovated and relocated to SPS Point 5. This allowed to deploy at the SPS the Beam Energy Tracking System (BETS) and the Trigger Synchronization Unit (TSU), initially designed for and operational at the LHC Beam Dumping System (LBDS).

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. [...]

SPS Beam Dump System (SBDS) Commissioning After Relocation and Upgrade / Van Trappen, Pieter (CERN) ; Carlier, Etienne (CERN) ; Ducimetière, Laurent (CERN) ; Namora, Vasco (CERN) ; Senaj, Viliam (CERN) ; Velotti, Francesco (CERN) ; Voumard, Nicolas (CERN)
In order to overcome several machine limitations, the SBDS has been relocated from LSS1 (Long Straight Section 1) to LSS5 during LS2 (Long Shutdown 2) with an important upgrade of the extraction kicker installation. An additional vertical deflection kicker magnet (MKDV) was produced and installed while the high voltage (HV) pulse generators have been upgraded by changing gas-discharge switches (thyratrons and ignitrons) to semiconductor stacks operating in oil. [...]

Overview of the Machine Learning and Numerical Optimiser Applications on Beam Transfer Systems for LHC and Its Injectors / Velotti, Francesco (CERN) ; Barnes, Michael (CERN) ; Carlier, Etienne (CERN) ; Dutheil, Yann (CERN) ; Fraser, Matthew (CERN) ; Goddard, Brennan (CERN) ; Magnin, Nicolas (CERN) ; Ramjiawan, Rebecca (CERN) ; Renner, Elisabeth (CERN) ; Van Trappen, Pieter (CERN) et al.
Machine learning and numerical optimisation algorithms are getting more and more popular in the accelerator physics community and, thanks to the computing power available, their application in daily operation more likely. In the CERN accelerator complex, and specifically on the beam transfer systems, many promising exploitation of these numerical tools have been put in place in the last years. [...]

Use of Multi-Network Fieldbus for Integration of Low-Level Intelligent Controller Within Control Architecture of Fast Pulsed System at CERN / Voumard, Nicolas (CERN) ; Boucly, Christophe (CERN) ; Pimentel, Marco (CERN) ; Strobino, Léa (CERN) ; Van Trappen, Pieter (CERN)
Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance.

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. [...]
