Industrialisation of precision cavity beam position monitors

Lead Research Organisation: Royal Holloway, University of London
Department Name: Physics

Abstract

The project is a response to the increasing demand for precision position diagnostics from modern accelerator facilities both inside and outside the high energy physics, e.g. free electron lasers and lepton colliders. An essential goal of this project is to equip the UK manufacturing industry with the knowledge and technologies required for series production of beam position systems. This would result in an improved competitiveness of the hi-tech UK products and position the UK industry to be well prepared bidders providing instrumentation for potential future national, European and international small and large scale projects. The use of technology will also benefit other disciplines such as biological and medical sciences, chemistry and security through improved technologies and higher quality beams.

Description We have developed a technology for low-cost manufacturing of precision cavity beam position monitors for electron accelerators. These devices can detect the transverse position of an electron beam within a vacuum beampipe of an accelerator with nanometre resolution. Normally, these devices require tight machining tolerances and complicated manufacturing processes. Our designs use simplified manufacturing techniques for improved cost efficiency and repairability for the benefit of the wider accelerator community, such as linear accelerators and free electron lasers. Currently, the effort is focused on converting our designs into commercially available products and creating first user cases.
Exploitation Route Our designs have now become commercial products with the first use cases emerging in the accelerator and free electron laser facilities worldwide.

Description Our designs have been industrialised and the first examples of commercial use are emerging. The first user is going through their tender process at the time of this submission and outcomes expected shortly after this submission closes. We aim to further promote our devices so they become a standard diagnostic in future electron linear accelerators and free electron lasers.

Title Cavity BPM sensor design 
Description The license granted to FMB-Oxford covers the design of two electromagnetic sensor cavities used as beam position, and beam arrival time and charge monitors respectively. The devices are applicable in a wide range of facilities operating relativistic electron or positron beams, such as free electron lasers, particle colliders as well as smaller scale test and user facilities.

Impact A UK SME FMB-Oxford specialising in experimental beamline hardware for synchrotron light sources now offers a completely new line of products. It is a new area for the company expanding into electron beam diagnostics. It is also a new area of technical expertise for the company in radio frequency and microwave technology, all resulting from RHUL knowledge transfer. The targeted users of this instrumentation are small and medium size facilities delivering electron beams which in the future will drive free electron lasers and Compton-scattering based X-ray sources. Such facilities have a wider impact in the community using intense light, such as biological and material sciences.
