09:15 → 10:15 FEL X-band issues

I will give an overview on the SwissFEL project at PSI, a free electron laser facility in the Angstrom wavelength region. Compared to current facilities, it features a very compact footprint, enabled by compression ratios allowing operation at relatively low beam energy. The subsequent bunch compression section require a precise and rather complex manipulation of the longitudinal phase space of the beam, which influences the choice of the frequency of the RF structures and has a strong impact on the tolerances of the RF system. Part of the FEL related R&D program is the development of an X band RF structure, which is done in collaboration with CERN and Sinchrotrone Trieste. The 72 cell structure using a 5pi/6 phase advance is part of the system manipulating the longitudinal phase space and has wake field monitors ensuring a precise alignment. I will describe the design and show the current state of fabrication.

Speaker: Dr Micha Dehler (PSI)
