CLIC BDS Day

CERN, Room 28-S-029, November 22, 2005

Motivation:

• In view of the goal to establish CLIC feasibility by 2010 it seems timely to review the status of the beam delivery system (BDS). The BDS day will organize a coherent effort to improve the beam delivery performance and to solve open design issues.

Draft Agenda:

Topics:

• CLIC R&D issues, goals, parameters and plan

• Beam-beam effects in CLIC & IP beam parameter choice

• Overview of present CLIC beam delivery system design   

• Highlights of the CERN CLIC stabilization & feedback study

• Progress on LAPP CLIC stabilization study

• Progress on nonlinear collimation  

• Tracking studies of the CLIC BDS

• Integrated simulations of luminosity performance

• Tuning simulations

• Tolerances   

• Raimondi-Seryi final-focus matching

• MAD-X developments (e.g., nonlinear matching in PTC)

• PLACET developments

• Halo studies

• Extraction line studies

• Selected IR issues, e.g., detector integrated dipole, 2-d octupole folding, solenoid

• Crab cavities and wake fields in the beam delivery system

• BDS nonlinear aberrations and spot size limits

• Slow and fast feedbacks

• Diagnostics

• Collimator technology
