  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.

  Recently, new geometries for superconducting crabbing and deflecting cavities have been developed that have significantly improved properties over those the standard TM110 cavities. They are smaller, have low surface fields, high shunt impedance and, more importantly for some of them, no lower-order-mode with a well-separated fundamental mode. This talk will present the status of the development of these cavities.

WE1A03 Application of X-band Linacs linac, FEL, emittance, gun 724

  Since the late 80’s the development of Normal Conducting (NC) X-band technology for particle accelerators has made significant progress and has witnessed tremendous growth. The driving force behind this technological development has been, and is, the interest of the scientific community in the construction of a Multi-TeV e+e Linear Collider at a reasonable size and cost. The use of the X-band frequency allows for a much higher accelerating gradient per meter, when compared to the S and C bands. SLAC, with a major contribution from KEK, has been pioneering this development since the late 80’s in the framework of the NLC/JLC projects. Later, in 2007, the same technology was chosen by CERN for CLIC, the 12 GHz Linear Collider based on the Two-Beam Acceleration (TBA) concept. In addition to these applications, X-band technology is also rapidly expanding in the field of X-ray FELs and other photon sources where it shows great potential. Here, a selection of X-band projects as well as the main applications of this technology at different international laboratories, is reported. The paper also includes a brief report on X-band medical and industrial applications.
