/ Roncarolo, Federico (CERN) ; Bart Pedersen, Stephane (CERN) ; Belleman, Jeroen (CERN) ; Belohrad, David (CERN) ; Bozzolan, Michele (CERN) ; Bracco, Chiara (CERN) ; Di Carlo, Salvatore (CERN) ; Emery, Jonathan (CERN) ; Goldblatt, Aurélie (CERN) ; Guerrero, Ana (CERN) et al.
The LHC injectors Upgrade (LIU) program has been fully implemented during the second long shutdown (LS2), which took place in 2019-20. In this context, new or upgraded beam instrumentation was developed to cope with H⁻ beam in LINAC4 and the new Proton Synchrotron Booster (PSB) injection systems which would provide high brightness proton beams in the rest of the injector complex.

Matching Studies Between the CERN PSB and PS Using Turn-by-Turn Beam Profile Acquisitions with a Residual Beam Gas Ionisation Monitor
/ Fraser, Matthew (CERN) ; Coly, Marcel (CERN) ; Guerrero, Ana (CERN) ; Huschauer, Alexander (CERN) ; Jensen, Steen (CERN) ; Levasseur, Swann (CERN) ; Roncarolo, Federico (CERN) ; Rossi, Adriana (CERN) ; Sandberg, Hampus (CERN) ; Storey, James (CERN)
In the framework of the LHC Injectors Upgrade project, the Beam Gas Ionisation (BGI) profile monitors installed in the Proton Synchrotron (PS) were fitted with a gas injection system capable of boosting the signal rate high enough to capture single turn acquisitions immediately after injection. This contribution reports on the studies carried out during the beam commissioning of the BGI system in a turn-by-turn matching monitor mode for its eventual implementation in an optimisation framework to preserve emittance during transfer between the PS Booster and PS.

In the framework of the LHC Injector Upgrade (LIU) project, the Proton Synchrotron Booster (PSB) will be extensively modified during the Long Shutdown 2 (LS2, 2019-2020) at CERN [1]. This includes a new injector, Linac4, which will provide a 160 MeV H⁻ beam and a complete new injection section for the PSB composed essentially of a chicane and a stripping foil system. [...]

The construction, installation and initial commissioning of CERN's LINAC4 was completed in 2016 with H⁻ ions successfully accelerated to its top energy of 160 MeV. The accelerator is equipped with a large number of beam diagnostic systems that are essential to monitor, control and optimize the beam parameters. [...]

During the Long Shutdown 2 (LS2) at CERN in 2019/20, the Proton Synchrotron Booster (PSB) will undergo a profound upgrade in the framework of the LHC Injector Upgrade (LIU) project involving also the connection to the new Linac4 injector. The 160 MeV Linac4 H' injection entails a complete replacement of the PSB injection section, including a stripping foil system, injection chicane, an H⁰/H' dump and novel beam instrumentation. [...]

Time-Resolved Transverse Beam Profile Measurements with a Rest Gas Ionisation Profile Monitor Based on Hybrid Pixel Detectors
/ Levasseur, Swann (Royal Holloway, U. of London) ; Bertsche, William (U.

Manchester (main)) ; Sapinski, Mariusz (Darmstadt, GSI) ; Satou, Kenichirou (JAEA, Ibaraki) ; Schneider, Gerhard (CERN) ; Storey, James (CERN) et al.
A novel rest gas ionisation profile monitor which aims to provide continuous, bunch-by-bunch and turn-by-turn measurement of the transverse beam profile has recently been in- stalled in the CERN Proton Synchrotron (PS) as part of the LHC Injector Upgrade (LIU) project. The instrument consists of an electric drift field to transport ionisation electrons produced by beam-gas interaction onto a measurement plane, and a magnetic field to maintain the transverse position of the ionisation electrons.

Beam Diagnostics Measurements at 3MeV of the LINAC4 $H^{−}$ Beam at CERN

As part of the CERN LHC injector chain upgrade, LINAC4 will accelerate H^{−} ions to 160 MeV, replacing the old 50 MeV proton linac. The ion source, the Low Energy Beam Transfer (LEBT) line, the 3 MeV Radio Frequency Quadrupole and the Medium Energy Beam Transfer (MEBT) line hosting a chopper, have been first commissioned in a dedicated test stand and are now tested in the LINAC4 tunnel.

Measuring the Beam Profile by Counting Ionization Electrons
/ Sandberg, Hampus (Manchester U. ; CERN) ; Bertsche, William (Manchester U.) ; Bodart, Dominique (CERN) ; Dehning, Bernd (CERN) ; Gibson, Stephen (Royal Holloway, U. of London) ; Levasseur, Swann (CERN) ; Satou, Kenichirou (J-PARC ; KEK, Tsukuba ; JAEA, Ibaraki) ; Schneider, Gerhard (CERN) ; Storey, James (CERN) ; Veness, Raymond (CERN)
The principle of non-destructive beam profile measurement with rest gas ionization electrons has remained largely unchanged since the technique was first proposed in the late 1960's. Ionization electrons (or ions) are transported by an electrostatic field onto an imaging detector, where the spatial distribution of detected electrons is a direct measure of the transverse beam profile.
