Wakefield Induced Correlated Energy Spread and Emittance Growth at TTF FEL

چکیده

An electron beam with a small energy spread (0.1%) and a small normalized emittance (2 mm.mrad) is required to drive a Free Electron Laser at the TESLA Test Facility (TTF) at DESY. During FEL operations, the longitudinal and transverse wakefields which are generated by vacuum components, principally by RF cavities, bellows and valves, will induce an additional energy spread and emittance growth, respectively. This paper presents the wakefields and its induced correlated energy spread and emittance growth at the TTF FEL of phase I and II.

Improvements in Emittance Wakefield Optimization for the Slac Linear Collider

The transverse emittances in the SLAC Linear Collider can be severely diluted by collective wakefield effects and dispersion. For the 1997/98 SLC/SLD run important changes were implemented in the way the emittance is optimized. Early in the linac, where the energy spread is large due to BNS damping, the emittance growth is dominated by dispersion. In this regime emittance tuning bumps may intro...

Bunch self-focusing regime of laser wakefield acceleration with reduced emittance growth.

A new regime of laser wakefield acceleration of an injected electron bunch is described. In this regime, the bunch charge is so high that the bunch wakefields play an important role in the bunch dynamics. In particular, the transverse bunch wakefield induces a strong self-focusing that suppresses the transverse emittance growth arising from misalignment errors. The decelerating longitudinal bun...

Measurements of the Transverse Emittance at the VUV-FEL

The TESLA Test Facility (TTF) linear accelerator (linac) at DESY has been extended to drive a new Free Electron Laser facility (VUV-FEL) in the wavelength range from the vacuum-ultraviolet (VUV) to soft Xrays. With the upgraded photo injector and increased electron beam energy up to 1GeV, wavelengths down to 6 nm can be achieved. During the commissioning phase of the VUV-FEL the emphasis is on ...

Development of a Femtosecond Soft X-ray SASE FEL at DESY

In this paper we describe the extension of the soft X-ray SASE FEL at the TESLA Test Facility (TTF) at DESY for generation of femtosecond pulses. The idea is based on a technique of \manipulating" the energy spread along the electron bunch. Since the radiation ampli cation process is extremely sensitive to the value of the energy spread, only that part of the electron bunch radiates which has l...

Innuence of Electron Beam Halos on the Fel Performance

For single-pass free electron lasers (FEL), such as ampli ers and SASE device, saturation of the radiation power has to be reached within the length of the undulator. Therefore, detailed knowledge of electron beam parameters is crucial. So far, simulations have been performed with a given rms emittance and energy spread. At short radiation wavelengths, bunch compressors are used to compress the...
