CW Operation of the European XFEL: SC-Gun Injector Optimization, S2E Calculations and SASE Performance
Dmitry Bazyl, Ye Chen, Martin Dohlus +1
This note presents optimization results for an injector with a super-conducting gun for the cw operation of the European XFEL, the corresponding start-to-end simulation calculation…
Superradiant Cherenkov-Wakefield radiation as THz source for FEL facilities
Klaus Floettmann, Francois Lemery, Martin Dohlus +3
An electron beam passing through a tube which is lined on the inside with a dielectric layer will radiate energy in the THz range due to the interaction with the boundary. The reso…
Axial representation of external electromagnetic fields for particle tracking in accelerators
Igor Zagorodnov, Martin Dohlus
We derive a power series representation of an arbitrary electromagnetic field near some axis through the coaxial field components on the axis. The obtained equations are compared w…
Detuning related coupler kick variation of a superconducting nine-cell 1.3 GHz cavity
Thorsten Hellert, Martin Dohlus
Superconducting TESLA-type cavities are widely used to accelerate electrons in long bunch trains, such as in high repetition rate free electron lasers. The TESLA cavity is equipped…
Efficient model for low-energy transverse beam dynamics in a nine-cell 1.3 GHz cavity
Thorsten Hellert, Martin Dohlus, Winfried Decking
FLASH and the European XFEL are SASE-FEL user facilities, at which superconducting TESLA cavities are operated in a pulsed mode to accelerate long bunch-trains. Several cavities ar…
Periodic Poisson Solver for Particle Tracking
M. Dohlus, Ch. Henning
A method is described to solve the Poisson problem for a three dimensional source distribution that is periodic into one direction. Perpendicular to the direction of periodicity a…
