WP6: Accelerator Performance and Concepts (APEC)


  • Compilation and classification of processes causing performance degradation in hadron storage rings and synchrotrons; ranking of the identified mechanisms according to their relative importance; identification and prioritization of mitigation approaches
  • Establish standard body of RAMS knowledge for particle accelerator applications; compile and rank existing RAMS standards, methods and practices in major laboratories; analysis of optimal RAMS characteristics for particle accelerator systems; spreading the identified best RAMS practices in order to introduce a common baseline; assessing the feasibility of an Open Data Infrastructure for accelerator reliability
  • Review of existing strategies & methods for beam-impedance assessments and impedance models; proposing and evaluating novel methods to reduce accelerator impedance; identification or development of strategies for electron-cloud mitigation at future accelerators; conceptual design of advanced beam feedback systems for future machines
  • Expanding synergies between proposed future ERL projects and operating or soon-to-be-commissioned linacs, recirculating linacs and ERLs in Europe; establishing a parameter database for the various facilities; examining innovative and alternative ERL approaches; working out synergies between linac developers and source developers for optimum beam quality; identifying outstanding open questions and develop prioritized R&D guidelines.
  • Analysis of the potential of crystals for charged-particle bending or particle acceleration; development of advanced photon colliders, including gamma-gamma and photon-nucleon colliders; assessment of advanced muon-collider concepts without ionization cooling; assessment of the potential use of large storage rings for gravitational wave detection or generation; assessing and ranking a basket of future concepts with regard to “future feasibility” and physics cases; delivering a white list of ranked future options
