24. PETS and drive beam development for CLIC

Igor SYRATCHEV (CERN)

The CLIC Power Extraction and Transfer Structure (PETS) is a large-aperture and low-impedance periodic structure, in which the RF power is generated by a bunched drive-beam current. The PETS design procedure and the HOM damping strategy which has been developed for the PETS is reviewed. Control of local RF power production by an "ON/OFF" mechanism is discussed as well. Finally, the PETS high...

25. High-Gradient Single-Cell Tests at X-Band

Dr Valery Dolgashev (SLAC)

We report results of ongoing high power tests of single cell standing wave structures. These tests are part of an experimental and theoretical study of rf breakdown in normal conducting structures at 11.4 GHz. The goal of this study is to determine the gradient potential of normal-conducting, rf powered particle beam accelerators. The test setup consists of reusable mode launchers and short...

26. Wakefield Computations for the CLIC PETS using the Parallel Finite Element Time-Domain Code T3P

Dr Arno Candel (SLAC)

01/12/2008, 14:40

In recent years, SLAC's Advanced Computations Department (ACD) has developed the high-performance parallel 3D electromagnetic time-domain code, T3P, for simulations of wakefields and transients in complex accelerator structures. T3P is based on advanced higher-order Finite Element methods on unstructured grids with quadratic surface approximation. Optimized for large-scale parallel processing...
