Generation of attosecond soft x-ray pulses in a longitudinal space charge amplifier

2013

A longitudinal space charge amplifier (LSCA), operating in soft x-ray regime, was recently proposed. Such an amplifier consists of a few amplification cascades (focusing channel and chicane) and a short radiator undulator in the end. Broadband nature of LSCA supports generation of few-cycle pulses as well as wavelength compression. In this paper we consider an application of these properties of LSCA for generation of attosecond x-ray pulses. It is shown that a compact and cheap addition to the soft x-ray free electron laser facility FLASH would allow to generate 60 attosecond (FWHM) long x-ray pulses with the peak power at 100 MW level and a contrast above 98%.Preprint submitted to Phys. Rev. ST-AB

“…Electron timing jitter is determined by the stability of several accelerator components (e.g., linac rf phase and amplitude, injector laser time jitter, etc.). It usually ranges from a few tens to several hundreds of femtoseconds [19][20][21][22]. Often being larger than the FEL pulse duration, these values can seriously limit the possibility of certain pump-probe experiments.…”

“…Although the present work was developed in the framework of an externally seeded FEL, the same technique can be implemented in other (not necessarily externally seeded) FEL facilities, once the electron-external laser interaction is ensured. This applies, e.g., to the FLASH facility where there is an existing optical replica diagnostic [3,20].…”

We present a new diagnostic method allowing one to reconstruct certain properties of a relativistic electron beam and of a laser pulse by looking at the result of their interaction. The latter takes place within an undulator and results in energy modulation of electrons. By taking advantage of the correlation between time and electron-beam energy, measurements of the electron-beam length, current and energy spread are possible simultaneously. Moreover, the scheme allows an accurate measurement of the timing jitter between the electron beam and the external laser and also of the laser’s actual pulse length at the interaction point. Experimental demonstration of the last two measurements is reported in this paper. Finally, this diagnostic method provides an independent measure of the energy transferred from the electron beam to free-electron laser light produced when seeded electrons are injected into a long undulator. Experimental results obtained at the FERMI free-electron laser are presented after a description of the proposed technique
