The Hadron Synchrotron Coherent effects (HSC) section provides expertise in the field of impedance computation and optimization, and multi-particle (collective) effects to study the coherent effects. The section is responsible for:
- Studies of the coherent effects limiting the performance of the present and future CERN accelerators (e.g. beam coupling impedance, space charge, beam-beam and electron cloud ) and of their mitigation
- Theoretical, simulation and experimental research in the dynamics of high-intensity and/or high-brightness hadron beams
- Impedance and beam-induced RF heating computations, measurements and follow-up
- Development and maintenance of software tools to study coherent multi-particle beam dynamics (e.g. PyHEADTAIL, PyECLOUD, etc.)
- Optics database, aperture models, and aperture checks for the PS and SPS complex.
The section contributes to machine coordination and beam physics support for commissioning and operation (e.g., parameter definition, strategy, measurement procedures) of CERN hadron synchrotrons. The section hosts the co-ordination of the machine studies of LHC injectors’ complex and of the LHC Injectors’ Upgrade (Deputy Project Leader). The section provides the Territorial Safety Coordinator (TSO) for the buildings (6,8,10 and 231) and the Group Coding Officer for the naming of equipment under the responsibility of the ABP group. The section also provides expertise for educational and outreach activities.
