Real-time processing of longitudinal Schottky signals in CERN’s antiproton chain
/ Niccolini, Marco (CERN) ; Barrientos, Diego (CERN) ; Suminski, Maciej (CERN) ; Angoletta, Maria Elena (CERN) ; Soderen, Martin (CERN) ; Freyermuth, Pierre (CERN) ; Brischetto, Ylenia (CERN)
A low-latency, real-time diagnostic system for the analysis of longitudinal Schottky signals in CERN’s antiproton chain has been developed. The system, installed in CERN’s Antiproton Decelerator (AD), processes the combined output of two low-noise, wideband AC beam transformers. [...]

Operation and New Capabilities of CERN's Digital LLRF Family for Injectors
/ Angoletta, Maria Elena (CERN) ; Findlay, Alan (CERN) ; Rey, Anthony (CERN) ; Bielawski, Bartosz Przemyslaw (CERN) ; Barrientos, Diego (CERN) ; Suminski, Maciej (CERN) ; Soderen, Martin (CERN) ; Jaussi, Michael (CERN) ; Albright, Simon (CERN) ; Brischetto, Ylenia (CERN) et al.
CERN’s digital Low-Level RF (LLRF) family for injectors is deployed on CERN’s PS Booster (PSB), Low Energy Ion Ring (LEIR), Extra Low ENergy Antiproton (ELENA) ring and Antiproton Decelerator (AD). It implements multiple capabilities, including beam and cavity feedback loops, bunch shaping, longitudinal blowup, bunch splitting and longitudinal diagnostics.New capabilities are now available and the LLRF family is soon going to be deployed for tests also in CERN’s Proton Synchrotron (PS).

Digital Low-Level RF System for the CERN Linac3 Accelerator
/ Valuch, Daniel (CERN) ; Alemany-Fernández, Reyes (CERN) ; Brischetto, Ylenia (CERN) ; Faeroe, Sindre (CERN) ; Piccinini, Giampaolo (CERN) ; Soderen, Martin (CERN)
A major consolidation of the aging RF system of the CERN Linac3, the ion source for the whole CERN accelerator chain, started during the Long Shutdown II. The main changes were an upgrade of the analogue Low-Level RF system (LLRF) and replacement of the 350 kW tube amplifiers by a solid-state equivalent. [...]

Upgrade of the Control System for the LHC High Level RF
/ Brischetto, Ylenia (CERN) ; Arnaudon, Luca (CERN) ; Costa, Valter (CERN) ; Glenat, David (CERN) ; Landré, David (CERN)
The acceleration of particles in CERN’s Large Hadron Collider (LHC) is carried out by sixteen superconducting radiofrequency (RF) cavities. Their remote control is taken care of by a complex system which involves heterogeneous equipment and interfaces with a number of different subsystems, such as high voltage power converters, cryogenics, vacuum and access control interlocks.

Commissioning of a new digital transverse damper system at the PSB
/ Di Giovanni, Gian Piero (CERN) ; Antoniou, Fanouria (CERN) ; Blas, Alfred (CERN) ; Brischetto, Ylenia (CERN) ; Findlay, Alan (CERN) ; Kotzian, Gerd (CERN) ; Mikulec, Bettina (CERN) ; Sterbini, Guido (CERN)
At the CERN Proton Synchrotron Booster, PSB, an analog transverse damper system has been in operation since 1999, providing satisfactory operational results with the proton beam supplied by Linac2. As a consequence of the LHC Injectors Upgrade, the PSB will face new challenges imposed by higher intensity, injection and extraction energy. [...]

White-Rabbit Based Revolution Frequency Program for the Longitudinal Beam Control of the CERN PS
/ Perrelet, Damien (CERN) ; Brischetto, Ylenia (CERN) ; Damerau, Heiko (CERN) ; Oberson, Daniel (Fribourg, EIA) ; Sundal, Magnus (Lisbon, IST) ; Villanueva, Andrea (CERN)
The measured bending field of the CERN Proton Synchrotron (PS) is received in real-time by the longitudinal beam control system and converted into the revolution frequency used as set-point for beam phase and radial loops. With the renovation of the bending field measurement system the transmission technique is changed from a differential sequence of pulses, the so-called B-train, to a stream of Ethernet frames based on the White Rabbit protocol.
