High Intensity

Hadron Beams


Accelerator Physics and synchrotron Design

Coordinated by

HHH-APD is the 3rd Workpackage of the HHH Networking Activity


in the framework of CARE (Coordinated Accelerator R&D in Europe)

Main Objectives of the CARE-HHH APD collaboration

Detailed APD activities

APD1 – Interaction Region design for an LHC luminosity upgrade

APD2 – Optics design for booster synchrotrons in the SPS or LHC tunnel

APD3 – Impedance calculations for new experimental beam pipes and booster systems

APD4 – Generation of a structured list of intensity limits for the LHC operation

APD5 – Studies on electron cloud effects for very high-intensity bunches

APD6 – Studies on measurement procedures for nonlinear machine parameters

APD7 - Advanced theoretical studies on halo formation and loss mechanisms
