The Incoherent effects (INC) Section is responsible for theoretical, numerical and experimental studies and proposals for the mitigation of interleaved incoherent multi-particle effects (e.g. space charge, beam-beam, intra-beam scattering, e-cloud, cooling) affecting the performance of present and future circular accelerators. In particular, the INC section:
- Conducts studies on the impact of incoherent effects on emittance growth and beam lifetime in presence of non-linear lattice imperfections and other perturbations such as noise.
- Develops luminosity models for CERN’s present and future colliders based on simulations and measurements including all relevant underlying effects.
- DDevelops and maintains numerical codes and modules describing incoherent effects, including non-linear dynamics tools, and follow-up of associated computing resources’ needs.
- Contributes to machine coordination and beam physics support for commissioning and operation (e.g., parameter definition, strategy, measurement procedures) of CERN injectors, the LHC and their upgrade.
The INC section contributes to or is in charge of the following working groups and activities:
- E-beam working group to address e-cooling effects and developments for ELENA, AD and LEIR
- Space charge working group to address space charge effects and their impact on performance in the LHC proton and ion injector chain
- Beam-beam and luminosity working group and wire compensation studies.
- LHC Injectors Upgrade (LIU) project and Injectors Performance Panel (IPP)
- Physics Beyond Collider Studies (PBC)
- HL-LHC Work Package 2 - Beam Dynamics (WP2)
- Studies for the Compact LInear Collider (CLIC)
- Studies for the Future Circular Collider (FCC)
- Computing activities within the ABP group (ABP Computing Panel)
