HSI - Hadron Synchrotrons Incoherent effects

The HSI Section is responsible for:

  • Theoretical, numerical and experimental studies and proposals for the mitigation of incoherent linear and non-linear multi-particle effects (e.g. space-charge, beam-beam and intra-beam scattering) affecting the performance of present and future CERN hadron synchrotrons.
  • Development of luminosity models for CERN’s present and future hadron colliders based on simulations and measurements including all the underlying effects. 
  • Development and maintenance of the numerical codes and modules describing multi-particle incoherent linear and non-linear effects (e.g. pyORBIT, MADX SC module, SixTrack BB module), including the follow-up of associated computing resources’ needs.

The HSI Section contributes to machine coordination and provides beam physics support for commissioning and operation (e.g., parameter definition, strategy, measurement procedures) of CERN hadron synchrotrons. It contributes to the coordination of the machine studies for the LHC injectors’ complex.
