Tesla-fel 2002-05
A design of a superconducting 3.9 GHz cavity for the injector of the TTF FEL-User Facility is presented. The cavity will be located after the first TESLA module with eight 1.3 GHz cavities and before the first bunch compressor. The purpose of the cavity is to cancel nonlinear distortions in the longitudinal phase space due to the cosine-like curvature of the 1.3 GHz accelerating cavity voltage....
متن کامل2 2 M ay 2 00 2 Scheme for Attophysics Experiments at a X - ray SASE FEL
We propose a concept for production of high power coherent attosecond pulses in X-ray range. An approach is based on generation of 8th harmonic of radiation in a multistage HGHG FEL (high gain high harmonic free electron laser) configuration starting from shot noise. Single-spike phenomena occurs when electron bunch is passed through the sequence of four relatively short undulators. The first s...

متن کاملTHE AXIAL-VELOCITY DISTRIBUTION FUNCTION AND THE LONGITUDINAL SUSCEPTIBILITY OF AN e-BEAM IN A PLANAR WIGGLER FEL
This paper introduces a development of a normalized axial velocity distribution function and a susceptibility term for an electron beam m a planar wiggler FEL. The model includes the independent contributions of the energy spread and the angular spread, the ennttance and the betatron motion, to the axial velocity distribution function. In the case of an emittance dominated spread, the resulting...
متن کاملLimitations of Electron Beam Conditioning for Free-Electron Lasers
Several ideas have been proposed to ‘condition’ an electron beam prior to the undulator of a Free-Electron Laser (FEL) by increasing each particle’s energy in proportion to the square of its transverse betatron amplitude. This conditioning enhances FEL gain by reducing the axial velocity spread within the electron bunch. We demonstrate that for symplectic beamlines, and independent of the metho...
