/ Bursali, Hikmet (CERN) ; Andreazza, William (CERN) ; Khatri, Ghanshyambhai (CERN) ; Ramos Garcia, Maria Teresa (CERN) ; Storey, James (CERN) ; Vollenberg, Wil (CERN) ; Vollinger, Christine (CERN)
The beam gas ionization monitors (BGIs) are non-destructive instruments to measure the transverse beam profiles. With the goal to double the beam intensity in the injector chain for the High-Luminosity Large Hadron Collider (HL-LHC), any element contributing to the overall beam coupling impedance requires an in-depth impedance evaluation from the design stage.

A Snapshot of CERN Beam Instrumentation R&D; Activities
/ Lefèvre, Thibaut (CERN) ; Alves, Diogo (CERN) ; Boccardi, Andrea (CERN) ; Jackson, Stephen (CERN) ; Roncarolo, Federico (CERN) ; Storey, James (CERN) ; Veness, Raymond (CERN) ; Zamantzas, Christos (CERN)
The CERN accelerator complex stands out as an unique scientific tool, distinguished by its scale and remarkable diversity. Its capacity to explore a vast range of beam parameters is truly unparalleled, spanning from the minute energies of around a few keV and microampere antiproton beams, decelerated within the CERN antimatter factory, to the 6.8 TeV high-intensity proton beams that race through the Large Hadron Collider (LHC).

Towards a Timepix3 Radiation Monitor for the Accelerator Mixed Radiation Field: Characterisation with Protons and Alphas from 0.6 MeV to 5.6 MeV
/ Prelipcean, Daniel (CERN ; Munich, Tech. U.) ; Lerner, Giuseppe (CERN) ; Slipukhin, Ivan (CERN ; IES, Montpellier) ; Lucsanyi, David (CERN ; IES, Montpellier) ; Sandberg, Hampus (CERN) ; Storey, James (CERN) ; Martin-Holgado, Pedro (CNA, Seville) ; Romero-Maestre, Amor (CNA, Seville) ; Morilla García, Yolanda (CNA, Seville) ; García Alía, Rubén (CERN)
A Timepix3 detector with a 300 silicon sensor has been studied as a novel radiation monitor for the mixed radiation field at the Large Hadron Collider at CERN. This work describes a test campaign carried out at Centro Nacional de Aceleradores with quasi-mono energetic protons (alphas) from 0.6 (1) to 5 (5.6) MeV, where orthogonal irradiations are used to obtain an energy calibration, and a low-energy angular scan to estimate the front dead layer thickness of the sensor.

The Beam Gas Vertex (BGV) instrument is a novel non-invasive transverse beam profile monitor under development for the High Luminosity Upgrade of the Large Hadron Collider (HL-LHC). Its principle is based on the reconstruction of the tracks and vertices issued from beam-gas inelastic hadronic interactions. [...]

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.

A pair of operational Beam Gas Ionisation (BGI) profile monitors was installed in the CERN Proton Synchrotron (PS) at the beginning of 2021. These instruments use Timepix3 hybrid pixel detectors to continuously measure the beam profile throughout the cycle in the horizontal and vertical planes. [...]

The Beam Gas Vertex (BGV) instrument is a novel non-invasive beam profile monitor and part of the High Luminosity Upgrade of the Large Hadron Collider (LHC) at CERN. Its aim is to continuously measure emittance and transverse beam profile throughout the whole LHC cycle, which has not yet been achieved by any other single device in the machine. [...]

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.
