“…At present, light sources based on free-electron laser (FEL) facilities offer femtosecond tunable radiation in the domains of Hard X-ray-LCLS [3], SACLA [4], PAL-XFEL [5], SwissFEL [6], European XFEL [7]-and of VUV, Soft X-ray-FLASH [8], FERMI [9]. Among the recent trends of FEL developments, compact designs are in rapid development in replacing the relevant elements with alternative accelerator concepts or using novel schemes [10]. Within the EuPRAXIA concept [11,12], the interest is to consider a laser plasma based accelerator to drive an FEL.…”

Over the past 90 years, particle accelerators have evolved into powerful and widely used tools for basic research, industry, medicine, and science. A new type of accelerator that uses plasma wakefields promises gradients as high as some tens of billions of electron volts per meter. This would allow much smaller accelerators that could be used for a wide range of fundamental and applied research applications. One of the target applications is a plasma-driven free-electron laser (FEL), aiming at producing tunable coherent light using electrons traveling in the periodic magnetic field of an undulator. In this work, the plasma-based electron beams with the most promising qualities, designed in the framework of EuPRAXIA, are analyzed in terms of the FEL performance.

“…sides, initial large divergence and energy spread can induce emittance growth due to chromatic effects [34,35], which both dramatically reduce the expected gain. With an electron beam of typically 1 mrad divergence and 1 % energy spread, a straightforward amplification cannot be achieved [36]. But several strategies can be implemented to overcome those issues.…”

Laser Plasma Accelerators (LPA) can sustain GeV/m accelerating fields offering outstanding new possibilities for compact applications. Despite the impressive recent developments, the LPA beam quality is still significantly lower than in the conventional radio-frequency accelerators, which is an issue in the cases of demanding applications such as Free Electron Lasers (FELs). If the electron beam duration is below few tens of femtosecond keeping pC charges, the mrad level divergence and few percent energy spread are particularly limiting. Several concepts of transfer line were proposed to mitigate those intrinsic properties targetting undulator radiation applications. We study here the robustness of the chromatic matching strategy for FEL amplification at 200 nm in a dedicated transport line, and analyze its sensitivity to several parameters. We consider not only the possible LPA source jitters, but also various realistic defaults of the equipment such as magnetic elements misalignements or focussing strength errors, unperfect undulator fields, etc...

“…The pulse duration unique to LPWAs is intrinsically ultrashort, which is more than one order of magnitude shorter than those in X-ray free electron lasers (XFELs). The recent progresses in LPWA [16][17][18] allow efficient production of high quality electron beams in very high electric fields, moreover it has opened the possibility to design and conceive the compact setup [19].…”

Single-cycle attosecond pulses by Thomson backscattering of terahertz pulses

et al. 2018

The generation of single-cycle attosecond pulses based on Thomson scattering of terahertz (THz) pulses is proposed. In the scheme, a highquality relativistic electron beam produced by a laser-plasma wakefield accelerator (LPWA), is sent through suitable magnetic devices to produce ultrathin electron layers for coherent Thomson backscattering of intense THz pulses. According to numerical simulations, single-cycle attosecond pulse generation is possible with up to 1 nJ energy. The waveform of the attosecond pulses closely resembles that of the THz pulses. This allows for a flexible waveform control of attosecond pulses.
