First ILC Workshop

WG 1: Overall Design

Topics

Discuss on the overall design including the conventional facilities. The topics include:

  • Choice of the initial and final stage energies and the accelerating gradient.
  • Review of the machine parameters and their inter-relationship. Clarify the impact of their choices on the machine design.
  • Conventional facilities for the main liacs: Two-tunnels vs single-tunnel.
  • Damping ring design: Dog-bones to share the tunnels with the main linacs vs rings in separate tunnels.
  • Positron source: Undulator-based vs conventional designs. Priority of the polarized positrons?
  • Beam crossing angle at the interaction point.
  • Beam dynamics issues. Tolerances.
