/ 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. [...]

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).

The CERN SPS Low Level RF: embedded acquisition system for the Cavity-Controller and Beam-Control commissioning and diagnostics
/ Egli, J (CERN) ; Baudrenghien, P (CERN) ; Hagmann, G (CERN) ; Spierer, A (CERN) ; Suminski, M (CERN)
The CERN SPS Low Level RF (LLRF) has undergone a major upgrade, including the complete redesign of the 200MHz Cavity-Controller and the Beam-Control during the Long Shutdown (2018-21). This upgrade was motivated by the required doubling of the beam intensity in the SPS for the High Luminosity LHC project (HL-LHC). [...]

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.
