Funding:This project has received funding from the European Union’s Horizon 2020 Research and Innovation programme under Grant Agreement No 730871. ARIES* is an EU-sponsored programme for accelerator research and innovation. An international Workshop was held online as part of this programme in June 2021 on the topic of ’Materials and Engineering Technologies for Particle Accelerator Beam Diagnostic Instruments’. The aim of the Workshop was to bring together instrument designers, experts and industry and research groups to review the state of the art in the field, present designs and discuss future challenges, whilst also developing and strengthening collaborations between groups. There were sessions covering ’Instrument design and operation’, ’Novel materials and applications’ and ’New technology and components’ over the three half-days of the on-line meeting. This paper will review the key topics presented at the workshop along with a summary of discussions held and proposed directions for future studies. * https://aries.web.cern.ch

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 BGV consists of a gas target and a forward tracking detector to reconstruct tracks and vertices resulting from beam-gas interactions. The beam profile is inferred from the spatial distribution of the vertices, making it essential to achieve a very good vertex resolution. Extensive simulation studies are being performed to provide a basis for the design of the future BGV. The goal of the study is to ascertain the requirements for the tracking detector and the gas target within the boundary conditions provided by the feasibility of integrating it into the LHC, budget and timescale. This contribution will focus on the simulations of the forward tracking detector. Based on cutting-edge track and vertex reconstruction methods, key parameter scans and their influence on the vertex resolution will be discussed.
