To estimate the vertical impedance of more complex geometry as an In-Vacuum Undulator we cross-checked first the results for simple geometries. Axially symmetric tapered structure and rectangular structures are under discussion. Comparison of analytical results with numerically obtained data using different EM Field Solvers. Two types of the In-Vacuum Undulator have been analyzed, the...

The Compact Linear Collider (CLIC) aims for electron-positron collisions with high luminosity at a nominal centre-of-mass energy of 3 TeV. Pre-Damping Rings (PDRs) and Damping Rings (DRs) are required for reducing the emittance of the electron and positron beams before it is injected into the booster linac. Several stripline kicker systems will be used to inject and extract the beam from the...
