The Compact Linear Collider (CLIC) study explores the scheme for an electron-positron collider with high luminos-ity and a nominal centre-of-mass energy of 3 TeV: CLIC will complement LHC physics in the multi-TeV range. The CLIC design relies on the presence of Pre-Damping Rings (PDR) and Damping Rings (DR) to achieve, through syn-chrotron radiation, the very low emittance needed to ful-fill the luminosity requirements. The specifications for the kicker systems are very challenging and include very low beam coupling impedance and excellent field homogene-ity: striplines have been chosen for the kicker elements. Analytical calculations have been carried out to determine the effect of tapering upon the high frequency beam cou-pling impedance. In addition detailed numerical modeling of the field homogeneity has been performed and the sen-sitivity of the homogeneity to various parameters, includ-ing stripline cross-section, have been studied. This paper presents the main conclusions of the beam impedance cal-culations and field homogeneity predictions.
