| TUPAB278 | The HL-LHC Beam Gas Vertex Monitor - Simulations for Design Optimisation and Performance Study | 2120 |
|
||
| The Beam Gas Vertex (BGV) instrument is a non-invasive transverse beam profile monitor being designed as part of the High Luminosity Upgrade of the LHC (HL-LHC) at CERN. Its aim is to continuously measure bunch-by-bunch beam profiles, independent of beam intensity, throughout the LHC cycle. The primary components of the BGV monitor are a gas target and a forward tracking detector. Secondary particles emerging from inelastic beam-gas interactions are detected by the tracker. The beam profile is then inferred from the spatial distribution of reconstructed vertices of said interactions. Based on insights and conclusions acquired by a demonstrator device that was operated in the LHC during Run 2, a new design is being developed to fulfill the HL-LHC specifications. This contribution describes the status of the simulation studies being performed to evaluate the impact of design parameters on the instrument’s performance and identify gas target and tracker requirements. | ||

Non Invasive Bunch Length Measurements Exploiting Cherenkov Diffraction Radiation | |
|
||
| Cherenkov Diffraction Radiation (ChDR) refers to the emission of broadband electromagnetic radiation which occurs when a charged particle propagates at relativistic speed in the vicinity of a dielectric material. At variance with the better-known Cherenkov radiation, ChDR is a non-invasive technique, that is the particle beam does not impinge on the dielectric radiator. ChDR also possesses other interesting features like a relatively high light yield, a broadband spectrum of emission and the emission at a relatively large angle with respect to the beam trajectory. Due to its potential, CERN initiated over the last few years several studies on ChDR-based diagnostics techniques. In this contribution I will focus on the exploitation of ChDR for non-invasive bunch length measurement, from proof of principle tests performed at the CLEAR facility at CERN and CLARA at Daresbury laboratory to current developments for experiments and facilities such as AWAKE and FCC | ||
