Beam Intercepting Devices Engineering (BDE)

Core competencies:

Engineering of primary beam-intercepting devices, including collimators, targets, beam dumps, absorbers, masks, stoppers, slits, scrapers, crystal-based devices, focusing magnetic horns and associated equipment.

Core responsibilities:

  • Act as equipment owner and manage the full lifecycle of primary beam-intercepting devices.
  • Deliver conceptual and detailed design, thermo-mechanical assessment, materials and cooling development, manufacturing follow-up, installation, testing, maintenance and upgrade.
  • Provide operational support, expert interventions and design improvements based on operational experience.
  • Develop remote-handling solutions and manage radioactive-device waste packaging with the relevant HSE teams.
  • Operate the Group’s mechanical workshop and Concept Development Office for prototyping, tooling, assembly and exploratory design.
  • Ensure the safe, compliant and sustainable lifecycle of beam-intercepting devices and Section’s workshops through engineering and technical excellence, risk management and ALARA considerations for design and maintenance.

Projects and Assigned Responsibilities:
