Beam instrumentation concerns the technologies needed to make direct measurements of beam observables such as beam position, intensity and size. These observations provide the diagnostic information to operate and improve the performance of accelerators and the associated transfer lines. For example, in order to maximize the collision rate at colliders - accelerator operators & physicists need measurements of the beam size throughout the acceleration cycle. Development of such an instrument for the LHC has proven to be particularly challenging, since the energy of the beam is too high to measure the profile by interacting directly with the beam itself. The aim of this project will be to develop a beam profile monitor for the LHC which is based on an idea first proposed in the 1960’s that allows to measure the beam profile (& other beam parameters) without interacting directly with the beam - but updated with cutting edge Timepix4 hybrid pixel detector technology that has been developed recently at CERN. A Beam Gas Ionisation (BGI) beam profile monitor is based on the detection of the residual particles that inevitably pervade the beampipe’s vacuum and which undergo ionisation as the beam flies through the pipe. The charged particles are directed towards the monitor by electromagnetic fields and - in the case of the LHC devices - will be directly detected by Timepix4 hybrid pixel detectors, its core element. The beam size is then inferred from the distribution of the detected electrons in real time, and the data organised to create a footage of the beam size evolution.
