TUYMH01	Status of the Future Circular Collider Study	collider, hadron, lepton, optics	34
	M. Benedikt CERN, Geneva, Switzerland
	Following the 2013 update of the European Strategy for Particle Physics, the international Future Circular Collider (FCC) Study has been launched by CERN as host institute, to design an energy frontier hadron collider (FCC-hh) in a new 80-100 km tunnel with a centre-of-mass energy of about 100 TeV, an order of magnitude beyond the LHC's, as a long-term goal. The FCC study also includes the design of a 90-350 GeV high-luminosity lepton collider (FCC-ee) installed in the same tunnel, serving as Higgs, top and Z factory, as a potential intermediate step, as well as an electron-proton collider option (FCC-he). The physics cases for such machines will be assessed and concepts for experiments will be developed in time for the next update of the European Strategy for Particle Physics by the end of 2018. The presentation will summarize the status of machine designs and parameters and discuss the essential technical components to be developed in the frame of the FCC study. Key elements are superconducting accelerator-dipole magnets with a field of 16 T for the hadron collider and high-power, high-efficiency RF systems for the lepton collider. In addition the unprecedented beam power presents special challenges for the hadron collider for all aspects of beam handling and machine protection. First conclusions of geological investigations and implementation studies will be presented. The status of the FCC collaboration and the further planning for the study will be outlined.

	VEPP-2000 is electron-positron collider exploiting the novel concept of round colliding beams. After three seasons of data taking in the whole energy range of 160-1000 MeV per beam it was stopped in 2013 for injection chain upgrade. The linking to the new BINP source of intensive beams together with booster synchrotron modernization provides the drastic luminosity gain at top energy of VEPP-2000. Recomissioning status, fist results and perspectives of the VEPP-2000 complex will be presented.

THCASH01	Effective RF Deflecting Structures for Bunch Rotation and Deflection	emittance, operation, linac, RF-structure	201
	V.V. Paramonov RAS/INR, Moscow, Russia
	Deflecting RF Structures find now applications for the bunch rotation with the purposes of diagnostic for the longitudinal distribution, emittance exchange and for the luminosity improvements in colliders. Report describes results of R&D program for development of deflectors with minimized level of aberrations in the distribution of deflecting field. Such structures, applied for bunch rotation along transverse axis, provide much smaller emittence growth, as compared to another options. In comparison with classical and widely used deflectors, based on disk loaded waveguide, developed structures have, depending on modification, in 2-6 times higher RF efficiency. Structures can operate both in Traveling Wave (TW) and in Standing Wave (SW) modes. To create long RF cavities for SW operation, compensated (bi-periodical) options are developed, combining field stability and high RF efficiency. The problem of stabilization for the plane of deflection is removed due to essentially 3D geometry. The main solutions for such structures development are described and achieved parameters are reported.

THCBSH04	The Monitoring of the Effects of Earth Surface Inclination With the Precision Laser Inclinometer for High Luminosity Colliders	laser, monitoring, collider, optics	210

	Earth surface movements, like earthquakes or industrial noise, can induce a degradation of particle accelerator instantaneous luminosity or even sudden beam losses. This report introduces the HL-LHC project and discusses the importance of monitoring the effects of earthquakes on the present LHC beam orbit and luminosity using a novel instrument, the Precision Laser Inclinometer (PLI). After a brief description of the instrument principles, a comparison of data from the PLI and from the LHC beam instrumentation in the event of earthquakes is given. The aim is to characterize the response of the accelerator to remote or nearby Earth surface movements. The first results from simulation in comparison with data are presented. The impact of vibrations on high luminosity small-sized beam colliders, as in High Luminosity LHC among many other future projects, the possible applications of the PLI instrument and ideas about possible feedback systems conclude the contribution.
