CERN accelerators underwent a period of long shutdown from the end of 2018 to 2020. During this time frame, significant hardware and software upgrades have been put in place to increase the performance of both proton and ion accelerator chains in the

During run 2 (2015-2018) the LEIR machine experienced several important improvements in terms of extracted intensity, driven by the LHC Injectors Upgrade (LIU) project requirements. In 2018 the machine not only gave another step forward in extracted

MD4036: New ADT signal processing for large tune acceptance

Autor: Komppula, Jani Paavo Olavi, Buffat, Xavier, Kotzian, Gerd, Li, Kevin Shing Bruce, Valuch, Daniel

Transverse feedback system (ADT) performance can be optimized with digital FIR filters. The current LHC and SPS ADT signal processing schemes consist of Notch and Hilbert filters (total length 8-taps) for removing the closed orbit offsets and correct

Commissioning of a new digital transverse damper system at the PSB

Autor: Di Giovanni, Gian Piero, Antoniou, Fanouria, Blas, Alfred, Brischetto, Ylenia, Findlay, Alan, Kotzian, Gerd, Mikulec, Bettina, Sterbini, Guido

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 P

Recurrent beam dumps significantly perturbed the operation of the CERN LHC in the summer months of 2017, especially in August. These unexpected beam dumps were triggered by fast beam losses that built up in the cryogenic beam vacuum at the half-cell
