The Compact LInear Collider (CLIC) aims at colliding ee beams at 1.5 TeV with effective transverse spot sizes of 60 nm (horizontal) times 0.7 nm (vertical). Strict stability tolerances must be respected in order to achieve a sufficient overlap of the two colliding beams. A stability test stand has been set up at CERN, bringing latest stabilization technology to the accelerator field. Using this...

Jet flavour identification in multi-TeV ee collisions is expected to provide insights on new phenomena at scales beyond those probed by the LHC. The anticipated high track density and jet collimation represent a new challenge to jet tagging algorithms. A method, based on the sampling of the jet charged multiplicity, sensitive to the long decay length and large decay multiplicity of heavy flavou...

The determination of the smuon mass at the Clicmulti-TeV ee linear collider has been studied for two CMSSM benchmarks. Results are given for both the analysis of the muon energy spectrum and the threshold scan method. The effects of detector resolution, beam-beam interactions and accelerator-induced backgrounds are discussed. The energy spectrum technique is also applied to the t̃ → tg̃ process t...

The feasibility of a CLIC-LHC based FEL-nucleus collider is investigated. It is shown that the proposed scheme satisfies all requirements of an ideal photon source for the Nuclear Resonance Fluorescence method. The physics potential of the proposed collider is illustrated for a beam of Pb nuclei. Particle Accelerator Conference (PAC'05), Knoxville, Tennessee, USA, May 16-26 2005 Geneva, Switzer...

The Compact Linear Collider (CLIC) targets a nanometer beam size at the collision point. Realizing this requires generation and transport of ultralow emittance beams. Dynamic imperfections can deflect colliding beams, leading to with relative offset. They also degrade each beam. Both these effects significantly impact luminosity CLIC. In paper, we examine newly considered dynamic imperfection: ...

Plasma Wake-Field Acceleration (PWFA) has demonstrated acceleration gradients above 50 GeV/m. Simulations have shown drive/witness bunch configurations that yield small energy spreads in the accelerated witness bunch and high energy transfer efficiency from the drive bunch to the witness bunch, ranging from 30% for a Gaussian drive bunch to 95% for bunch with triangular shaped longitudinal prof...
