Away-Day

A review of the CLIC parameters at 1 and 3 TeV (5 TeV?) in order to re-define new "target' parameters taking into account: - the new model of the multibunch accelerating structure, - the new drive beam scheme, - the beam simulations with multibunches. Suggested schedule: 7 Present parameters and objectives of the review (moderator: J.P. Delahaye). The multibunch accelerating structure (moderator: I. Wilson) Best guess of the RF parameters - Optimisation of RF to beam efficiency. Single bunch and multibunches parameters (moderator: G. Guignard) Charge per bunch and bunch length, minimum vertical emittance Number of bunches and separation between bunches. Constraints and freedom from new drive beam scheme (moderator: R. Ruth) RF pulse length, accelerating gradient. Power linac (moderator: L.Thorndahl) 1 TRS powering 1, 2 or 4 CAS?, focusing. CLIC module (moderator: W.Wuensch) layout of the main and drive module, improving the filling factor. Injector complex of the main beam (moderator: L.Rinolfi) Adaptation to higher number of bunches and lower repetition rate Reducing capital cost and interferences between e+ and e- production. Conclusion: update of new target parameters at 1 and 3 TeV (moderator: J.P. Delahaye)
