The LHC Injectors Upgrade (LIU) project was put in place between 2010 and 2021 to increase the intensity and brightness in the LHC injectors to match the challenging requirements of the High-Luminosity LHC (HL-LHC) project, while ensuring reliable operation of the injectors complex up to the end of the HL-LHC era (ca. 2040).

The CERN LHC injector chain underwent a major upgrade during the Long Shutdown 2 (LS2) in the framework of the LHC Injectors Upgrade (LIU) project. After 2 years of installation work, the Proton Synchrotron (PS) was restarted in 2021 with the goal to achieve pre-LS2 beam quality by the end of 2021. [...]

Summary of the First Fully Operational Run of LINAC4 at CERN
/ Skowroński, Piotr (CERN) ; Bellodi, Giulia (CERN) ; Bielawski, Bartosz Przemyslaw (CERN) ; Borner, Robert (CERN) ; Di Giovanni, Gian Piero (CERN) ; Gousiou, Evangelia (CERN) ; Lallement, Jean-Baptiste (CERN) ; Lombardi, Alessandra (CERN) ; Mikulec, Bettina (CERN) ; Parra-Lopez, Julien (CERN) et al.
In December 2020 the newly commissioned LINAC4 started delivering beam for the CERN proton accelerator chain, replacing the old LINAC2. LINAC4 is a 352 MHz normal conducting linac, providing a beam of negative hydrogen ions at 160 MeV that are converted into protons at injection into the PS Booster synchrotron. [...]

Improved Longitudinal Performance of the LHC Beam in the CERN PS

At the end of the 2018 run the intensity target for the High Luminosity LHC (HL-LHC) had just been reached at extraction from the Proton Synchrotron (PS). In the framework of the LHC Injectors Upgrade (LIU) project additional RF improvements have been implemented during the 2019/2020 long shutdown (LS2), mainly impacting the impedance of the 10 MHz, 40 MHz, and 80 MHz RF systems.

Achievements and Performance Prospects of the Upgraded LHC Injectors

To provide HL-LHC performance, the CERN LHC injector chain underwent a major upgrade during an almost 2-year-long shutdown. In the first half of 2021 the injectors were gradually re-started with the aim to reach at least pre-shutdown parameters for LHC as well as for fixed target beams. [...]

Optimised Transverse Painting Schemes for the New 160 MeV H$^-$ Injection System at CERN
/ Renner, Elisabeth (CERN ; TU Vienna) ; Albright, Simon (CERN) ; Antoniou, Fanouria (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Bracco, Chiara (CERN) ; Di Giovanni, Gian Piero (CERN) ; Mikulec, Bettina (CERN) ; Prebibaj, Tirsi (CERN ; Goethe U., Frankfurt (main)) ; Velotti, Francesco (CERN)
A major aspect of the LHC Injectors Upgrade (LIU) project at CERN is the Proton Synchrotron Booster (PSB) connection to the newly built Linac4 and the related installation of a new 160 MeV H$^-$ charge exchange injection. This contribution presents the first operational experience with the new injection system and its flexibility of applying horizontal phase space painting to tailor different beams to the respective user-defined brightness targets.

Resonance Compensation for High Intensity and High Brightness Beams in the CERN PSB

Resonance studies have been conducted during the recommissioning of the CERN Proton Synchrotron Booster (PSB) following the implementation of the LHC Injectors Upgrade (LIU) project. In particular, resonance identification through so-called loss maps has been applied on all four rings of the PSB, revealing various resonances up to fourth order. [...]
