/ Santamaría García, Andrea (CERN) ; Antoniou, Fanouria (CERN) ; Bartosik, Hannes (CERN) ; Briz Monago, Jose (CERN) ; Di Giovanni, Gian Piero (CERN) ; Guerrero Ollacarizqueta, Ana (CERN) ; Hunt, James (CERN) ; Mikulec, Bettina (CERN) ; Roncarolo, Federico (CERN) ; Senes, Eugenio (CERN) et al.
Transverse emittance measurements with wire scanners have been extensively studied across the accelerator complex at CERN due to their important role in characterizing the beams and their complicated modelling. In recent years, this topic has been of particular interest for the LHC Injectors Upgrade (LIU) project, where a tight transverse emittance blow-up budget between the Proton Synchrotron Booster (PSB) and the Proton Synchrotron (PS) is imposed to ensure the required beam brightness for the High Luminosity LHC (HL-LHC).

Systematic Studies of Transverse Emittance Measurements Along the CERN PS Booster Cycle
/ Santamaría García, Andrea (CERN) ; Albright, Simon (CERN) ; Bartosik, Hannes (CERN) ; Briz Monago, Jose (CERN) ; Di Giovanni, Gian Piero (CERN) ; Forte, Vincenzo (CERN) ; Mikulec, Bettina (CERN) ; Roncarolo, Federico (CERN) ; Vlachoudis, Vasilis (CERN)
The CERN Proton Synchrotron Booster (PSB) will need to deliver two times the current brightness to the Large Hadron Collider (LHC) after the LHC Injectors Upgrade (LIU) to meet the High-Luminosity-LHC beam requirements. Beam intensity and transverse emittance are the key parameters to increase brightness, the latter being more difficult to manipulate. [...]

New Longitudinal Beam Production Methods in the CERN Proton Synchrotron Booster
/ Albright, Simon (CERN) ; Antoniou, Fanouria (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Bracco, Chiara (CERN) ; Renner, Elisabeth (CERN ; TU Vienna)
As part of the LHC Injectors Upgrade (LIU) project, significant improvements were made to the CERN Proton Synchrotron Booster (PSB) during the 2019/2020 long shutdown, including a new Finemet-based wideband RF system, renovated longitudinal beam control, and a new magnetic cycle. To meet the requirements of the diverse experimental program, the PSB provides beams with intensities spanning three orders of magnitude and a large range of longitudinal emittances. [...]

Emittance dilution from the CERN Proton Synchrotron Booster’s extraction kickers
/ Fraser, Matthew (CERN) ; Albright, Simon (CERN) ; Antoniou, Fanouria (CERN) ; Di Giovanni, Gian Piero (CERN) ; Dutheil, Yann (CERN) ; Forte, Vincenzo (CERN) ; Huschauer, Alexander (CERN) ; Roncarolo, Federico (CERN)
Understanding the different sources of emittance dilution along the LHC injector chain is an important part of providing the high brightness proton beams demanded by the LHC Injectors Upgrade (LIU) project. In this context, the first beam-based measurements of the magnetic waveforms of the Proton Synchrotron Booster’s (PSB) extraction kickers were carried out and used to quantify the transverse emittance blow-up during extraction and transfer to the Proton Synchrotron (PS).

During LHC Run 1 significant transverse emittance growth through the LHC cycle was observed. Measurements indicated most of the blow-up to occur during the injection plateau and the ramp. [...]

Beam Commissioning of the New 160 MeV H⁻ Injection System of the CERN PS Booster

A key component to meeting the brightness targets of the LHC Injectors Upgrade (LIU) project at CERN is the new 160 MeV H⁻ charge exchange injection system into the Proton Synchrotron Booster. This system has been in beam commissioning since December 2020, optimizing the beam production schemes for tailoring different beams to the respective user-defined brightness targets. [...]

Experimental Investigations on the High-Intensity Effects Near the Half-Integer Resonance in the PSB

Space charge effects are the main limitation for the brightness performance of the Proton Synchrotron Booster (PSB) at CERN. Following the upgrades of the LHC Injectors Upgrade (LIU) project, the PSB delivered unprecedented brightness even exceeding the projected target parameters. [...]

Overview of the CERN PSB-to-PS Transfer Line Optics Matching Studies in View of the LHC Injectors Upgrade Project

At injection into the CERN Proton Synchrotron (PS) a significant horizontal emittance blow-up of the present high brightness beams for the LHC is observed. A partial contribution to this effect is suspected to be an important mismatch between the dispersion function in the transfer line from the PS Booster (PSB) and the ring itself. [...]
