	The longitudinal phase stability of CLIC main and drive beams is a crucial element of CLIC design. In order to measure and to control the phase, a distributed phase monitoring system has been proposed. The system measures the beam phase every 900 m. The relative phase between the measurement points is synchronized with an external reference system via a chain of reference lines. This paper presents the simulations of error propagation in the proposed distributed monitoring system and the impact on the drive and main beam phase errors and the luminosity. Based on the results the error tolerances for the proposed system are detailed.

SUPB038	Multipole Field Effects for the Superconducting Parallel-Bar Deflecting/Crabbing Cavities	dipole, multipole, cavity, superconductivity	92
	S.U. De Silva, J.R. Delayen ODU, Norfolk, Virginia, USA S.U. De Silva JLAB, Newport News, Virginia, USA
	The superconducting parallel-bar deflecting/crabbing cavity is currently being considered as one of the design options in rf separation for the Jefferson Lab 12 GeV upgrade and for the crabbing cavity for the proposed LHC luminosity upgrade. Knowledge of multipole field effects is important for accurate beam dynamics study of rf structures. The multipole components can be accurately determined numerically using the electromagnetic surface field data in the rf structure. This paper discusses the detailed analysis of those components for the fundamental deflecting/crabbing mode and higher order modes in the parallel-bar deflecting/crabbing cavity.

WE1A02	Status and Future of the CLIC Study	linac, emittance, target, damping	719
	R. Corsini CERN, Geneva, Switzerland
	The Compact Linear Collider (CLIC) International Collaboration is carrying out an extensive R&D program towards a multi-TeV electron-positron collider. The CLIC concept is based on the use of high-gradient normal-conducting accelerating structures in conjunction with a novel two-beam acceleration scheme, where the RF power needed to accelerate the colliding beams is extracted from a high-current drive beam running parallel to the main linac. In order to establish the feasibility of such concept a number of key issues were addressed, both experimentally and theoretically, and the results of the study were documented in the recently completed CLIC Conceptual Design Report (CDR). The conclusions reached in the CDR constitute also an important contribution to the European strategy group. A short summary of the present status with will be given, together with an outlook on the program for the next period, aimed at the preparation of an implementation plan.
