MOPRO029	Feed Forward Orbit Correction in the CLIC Ring to Main LINAC Transfer Lines	131
	R. Apsimon, A. Latina, D. Schulte, J.A. Uythoven CERN, Geneva, Switzerland
	The emittance growth in the betatron collimation system of the 27 km long transfer lines between the CLIC damping rings and the main LINAC depends strongly on the transverse orbit jitter. The resulting stability requirements of the damping ring extraction elements seem extremely difficult to achieve. Position and angle feed forward systems in these long transfer lines bring the specified parameters of the extraction elements within reach. The designs of the optics and feed forward hardware are presented together with tracking simulations of the systems.

MOPME049	Design Considerations of the Final Turnaround Regions for the CLIC Drive Beam	485
	R. Apsimon, J. Esberg, A. Latina, D. Schulte, J.A. Uythoven CERN, Geneva, Switzerland
	The optics design of the final turnaround regions for the CLIC drive beam is presented. This includes the extraction region, the turnaround loop and the phase feed forward chicane for correcting errors on the bunch phase. The design specifications of the kicker and septum magnets are provided. Tracking simulations and detailed studies of coherent and incoherent synchrotron radiation have been used to optimise the optics in the turnaround region in order to minimise transverse and longitudinal emittance growth.

TUPRO019	Localisation of Beam Offset Jitter Sources at ATF2	1049
	J. Pfingstner, H. Garcia, A. Latina, M. Patecki, D. Schulte, R. Tomás CERN, Geneva, Switzerland
	For the commissioning and operation of modern particle accelerators, automated error detection and diagnostics methods are becoming increasingly important. In this paper, we present two such methods, which are capable of localising sources of beam offset jitter with a combination of correlation studies and so called degree of freedom plots. The methods were applied to the ATF2 beam line at KEK, where one of the major goals is the reduction of the beam offset jitter. Results of this localisation are shown in this paper. A big advantage of the presented method is its high robustness especially to varying optics parameters. Therefore, we believe that the developed beam offset jitter localisation methods can be easily applied to other accelerators.

TUPRO063	Upgrade of Slicing and Tracking in MAD-X	1180
	H. Burkhardt, L. Deniau, A. Latina CERN, Geneva, Switzerland
	We describe the extension of the functionality of the slicing module and its applications in MAD-X. We can now select thick or thin slicing for individual quadrupoles or groups of quadrupoles and implemented tracking of thick quadrupoles and dipoles in MAD-X. Complex dipole magnets with fringe fields can now automatically be translated to simple bends with extra dipedges.

TUPRO064	Scaling Laws of Wake Field Effects for Gradient Changes in the CLIC Main Linac	1183
	J. Pfingstner, A. Latina, D. Schulte CERN, Geneva, Switzerland
	The main linac of CLIC is designed to maximize the transportable bunch charge, since this parameter determines the energy efficiency of the CLIC accelerating structures. The bunch charge is limited by short-range wake field effects, which increase the projected beam emittance. For the main linac cost optimisation, it is important to understand how the charge limit scales with the change of the gradient of the accelerating structures. In this paper, we determine such a scaling law via simulations studies. It is shown that from different possible scenarios, the charge limit for a lower gradient CLIC structure scales advantageous and a relatively high charge can be used.

	Tests of Beam-Based Alignment have been performed at FACET, with successful results. A flight simulator based on PLACET has been put in place to test the correction algorithms before applying the correction to the real machine. The flight simulator not only helped studying the parameters space in a safe environment, but it also helped developing a graphical interface that the experimenter can use to set each parameter of the correction also during the on-line.

TUPRO069	First Studies of Two-beam Tuning in the CLIC BDS	1195
	J. Snuverink JAI, Egham, Surrey, United Kingdom A. Latina, R. Tomás CERN, Geneva, Switzerland
	Beam tuning in the beam delivery system (BDS) is one of the major challenges for the future linear colliders. Up to now single beam tuning has been performed, both in simulations and experiments at the Accelerator Test Facility (ATF). However, in future linear colliders, due to fast detuning of the final focus optics both beamlines will need to be tuned simultaneously. In this paper a first two-beam tuning study for the Compact Linear Collider (CLIC) BDS is presented applying the usual toolbox of beam-based alignment (BBA) and sextupole knobs.

TUPME003	Effect of CSR Shielding in the Compact Linear Collider	1337
	J. Esberg, R. Apsimon, A. Latina, D. Schulte CERN, Geneva, Switzerland
	The Drive Beam complex of the Compact LInear Collider must use short bunches with a large charge making beam transport susceptible to unwanted effects of Coherent Synchrotron Radiation emitted in the dipole magnets. We here present the effects of transporting the beam within a limited aperture which decreases the magnitude of the CSR wake. The effect, known as CSR shielding, eases the design of key components of the facility.

	Within last decade a linear accelerating structure with an average loaded gradient of 100 MV/m at 12 GHz has been demonstrated in the CLIC study. Recently, it has been proposed to use the CLIC structure to drive an FEL linac. In contrast to CLIC the linac would be powered by klystrons not by a drive beam. The main advantage of this proposal is achieving the required energies in a very short distance, thus the facility would be rather compact. In this study, we present the conceptual design parameters of a facility which could generate laser photon pulses covering the range of 1-75 Angstrom. Shorter wavelengths could also be reached with slightly increasing the energy.

	Preliminary plans are presented for a sub-Angstrom wavelength XFEL at the Australian Synchrotron light source site. The design is based around a 6 GeV x-band linac from the CLIC Project. One of the motivations for the design is to have an XFEL co-located on the site with existing storage ring based synchrotron light source. The desire and ability of the Australian photon science community to win beamtime on existing XFELs has lead to this design study to plan for a future machine in Australia. The technology choice is also driven by the Australian participation in the CLIC Collaboration and the local HEP community.

	Tuning the CLIC Beam Delivery System (BDS), and in particular the final focus, is a challenging task. In simulations without misalignments, the goal is to reach 120~\% of the nominal luminosity target, in order to allow for 10~\% loss due to static imperfections, and another 10~\% loss from dynamic imperfections. Various approaches have been considered to correct the magnet misalignments, including 1-1 correction, dispersion free steering (DFS), and several minimization methods utilizing multipole movers. In this paper we report on the recent advancements towards a feasible tuning approach that reach the required luminosity target in a reasonable time frame.
