“…The LNF SPARC_LAB [ 6 ] research team has recently demonstrated that plasma-based acceleration technique can produce sufficiently high-quality particle beams able to drive a FEL in SASE (self-amplified spontaneous emission) and seeded configurations [ 18 ]. This research paves the way to the realisation of compact particle accelerators that can be used for research in different fields but also in other contexts like hospitals and industries.…”

“…At SPARC_LAB for the first time, using a high-quality beam, accelerated by a plasma wave, a FEL coherent radiation in the infrared range was generated. This result was achieved using a 3-cm-long capillary where a plasma was created, ionising hydrogen gas using a high voltage discharge, and after two electron bunches were injected, the first one used as driver to excite the plasma accelerating wave and the second as witness to be accelerated [ 18 ]. The high quality of the witness at the entrance of the plasma was preserved along the acceleration process and, in addition to the high current, was capable of driving a FEL to generate coherent light pulses that reached the energy of 30 nJ.…”

The INFN-Frascati National Laboratory (LNF) is nowadays running a 0.51 GeV electron-positron collider, DA NE, that also represents the synchrotron radiation source of the beamlines of the DA NE-Light facility. Not being DA NE dedicated to synchrotron radiations activities, the DA NE-Light facility can use it mainly in parasitic mode. Particle accelerators and high energy physics (HEP) have been and are the main core of the LNF research activity, but like other HEP international laboratories also LNF is now moving in the direction of developing a dedicated free electron laser (FEL) user facility, EuPRAXIA@SPARC_Lab, based on plasma acceleration. This new facility in the framework of the EuPRAXIA (European Plasma Research Accelerator with eXcellence in Applications) EU project should produce FEL radiation beams for a wide range of applications using a smaller accelerator compared to actual radio frequency-based accelerator sources dimensions.

“…Recent experiments have demonstrated that both charge and energy spread can be preserved in a PWFA [14][15][16] , and that a sufficient beam brightness can be maintained during a small energy boost while still allowing FEL gain to occur 17 . However, preservation of emittance at the level required for scaling to large energy gain has until now not been established.…”

Radio-frequency accelerators are engines of discovery, powering high-energy physics and photon science, but are also large and expensive due to their limited accelerating fields. Plasma-wakefield accelerators (PWFAs) provide orders-of-magnitude stronger fields in the charge-density wave behind a particle bunch travelling in a plasma, promising particle accelerators of greatly reduced size and cost. However, PWFAs easily degrade the beam quality of the bunches they accelerate. Emittance, which determines how tightly beams can be focused, is a critical beam quality in for instance colliders and free-electron lasers, but is particularly prone to degradation. We demonstrate, for the first time, emittance preservation in a high-gradient and high-efficiency PWFA while simultaneously preserving charge and energy spread. This establishes that PWFAs can accelerate without degradation—essential for energy boosters in photon science and multistage facilities for compact high-energy particle colliders.

“…Both can be further reduced considering the option of electron beams generated by laser plasma accelerators (LPAs). These last devices have made astounding progress in generating high-energy, high-quality electron beams, [24][25][26][27][28][29][30][31][32][33][34][35] to the point that they have already been tested in the production of betatron [36][37][38][39], undulator [40][41][42][43] and SASE and seeded free-electron laser radiation [44][45][46][47][48][49]. Active research and development efforts have also been pursued to conceive compact Compton sources [50][51][52][53][54] based on these novel LPA accelerators.…”

A Laser Frequency Transverse Modulation Might Compensate for the Spectral Broadening Due to Large Electron Energy Spread in Thomson Sources

et al. 2022

Compact laser plasma accelerators generate high-energy electron beams with increasing quality. When used in inverse Compton backscattering, however, the relatively large electron energy spread jeopardizes potential applications requiring small bandwidths. We present here a novel interaction scheme that allows us to compensate for the negative effects of the electron energy spread on the spectrum, by introducing a transverse spatial frequency modulation in the laser pulse. Such a laser chirp, together with a properly dispersed electron beam, can substantially reduce the broadening of the Compton bandwidth due to the electron energy spread. We show theoretical analysis and numerical simulations for hard X-ray Thomson sources based on laser plasma accelerators.
