First Operation for Stochastic Cooling of P-Bars in the CERN AD Using Optical Delay Notch Filter and Plans 2021 Operation
/ Höfle, Wolfgang (CERN) ; Arnaudon, Luca (CERN) ; Bjørsvik, Endre (CERN) ; Caspers, Fritz (CERN) ; Eriksson, Tommy (CERN) ; Louwerse, Reinier (CERN) ; Myklebust, Vebjorn Roed (CERN)
As part of the consolidation of the stochastic coolingsystem of the CERN Antiproton Decelerator a notch filter with optical delay lines has been developed. During the 2018 run of AD a notch filter with optical delay lines for the longitudinal stochastic cooling at 3.5 GeV/c was successfully tested with beam for the first time. [...]

Recommissioning of the CERN AD Stochastic Cooling System in 2021 after Long Shutdown 2
/ Höfle, Wolfgang (CERN) ; Carli, Christian (CERN) ; Caspers, Fritz (CERN) ; Dupuy, Bruno (CERN) ; Gamba, Davide (CERN) ; Louwerse, Reinier (CERN) ; Myklebust, Vebjorn Roed (CERN) ; Oliveira, Joao Carlos (CERN) ; Ponce, Laurette (CERN) ; Rey, Stephane (CERN) et al.
The power system of the Stochastic Cooling System of the anti-proton decelerator AD at CERN, installed on top of the shielding blocks of the AD ring, was completely dismantled during the long shutdown 2 (LS2) at the end of the 2018 run in order to gain access to the accelerator for magnet consolidation. At start-up, this required finding and verifying the correct delays for all 48 power amplifiers feeding to the two kickers by means of beam transfer functions for the two cooling plateaus at 3.57 GeV/c and 2 GeV/c.

CERN's Low Energy Ion Ring (LEIR) low-level RF (LLRF) system has been successfully upgraded in 2016 to the new digital, LLRF family for frequency-sweeping synchrotrons developed at CERN. For LEIR it implements not only beam loops but also the voltage and phase loops required for the control of two Finemet-based High-Level RF (HLRF) systems. [...]

A prototype wideband High-Level RF (HLRF) sys-tem based on Finemet metal alloy has been installed in CERN's PS Booster (PSB) Ring 4 in 2012, within the frame of the LHC Injectors Upgrade (LIU) project. A digital Low-Level RF (LLRF) system was used to control the HLRF system to ascertain the capabilities of the combined system, especially under heavy beam loading. [...]
