FEL Pulse Duration Evolution along Undulators at FLASH

چکیده
Self-amplified spontaneous-emission (SASE) free-electron lasers (FELs) deliver ultrashort pulses with femtosecond durations. Due to the fluctuating nature of radiation properties SASE FELs, characterizing FEL on a single-shot basis is necessary. Therefore, we use terahertz streaking characterize temporal extreme ultraviolet from laser in Hamburg (FLASH). In this study, pulse duration as well energy are measured wavelength range 8 34 nm functions undulators contributing lasing process. The results compared one-dimensional and three-dimensional, time-dependent simulations.

Chirped pulse amplification at VISA-FEL
Chirped beam manipulations are of the great interest to the FEL (Free Electron Laser) community as potential means of obtaining ultra short X-ray pulses. The experiment is under way at the ATF (Accelerator Test Facility) at BNL (Brookhaven National Laboratory) to study the FEL process limits with the under-compressed chirped electron beam. High gain near-saturation SASE operation was achieved w...
متن کاملBeam Based Alignment of the TESLA X-ray FEL undulators
One of the important parameters that determine the performance of the FEL is the overlap between electron beam and radiation field during the amplification process. An earlier study has shown that in order to maintain this overlap, quadrupoles have to be aligned with an accuracy of 1 m. In addition, first and second field integrals of the magnetic structures have to be corrected. Since this can...

This proposal aims to continue the preliminary experiments using SPPS, which demonstrated the feasibility of preforming XANES experiments on the femtosecond time scale. It also has the potential to provide a shot-by-shot measurement of the beam spectral profile. The instrument consists of a simple dispersive spectrometer coupled to an integrating position-sensitive detector. Experiments at NSLS...
متن کاملChirped Pulse Amplification of HGHG-FEL at DUV-FEL Facility at BNL
The DUV-FEL facility has been in operation in High Gain Harmonic Generation (HGHG) mode for one year producing 266 nm output from 177 MeV electrons. In this paper we present preliminary results of the Chirped Pulse Amplification (CPA) of HGHG radiation. In the normal HGHG process, a 1 ps electron beam is seeded by chirped 9 ps long 800 nm Ti:Sapphire laser. The electron beam sees only a narrow ...
متن کاملQuasi-real-time photon pulse duration measurement by analysis of FEL radiation spectra
For photon diagnostics at free-electron lasers (FELs), the determination of the photon pulse duration is an important challenge and a complex task. This is especially true for SASE FELs with strongly fluctuating pulse parameters. However, most techniques require an extensive experimental setup, data acquisition and evaluation time, limiting the usability in all-day operation. In contrast, the p...
