In an echo of the cluster of breakthrough laser wakefield acceleration experiments in the mid-2000’s, there have been multiple milestone experiments in the past few years demonstrating free electron lasers (FELs) powered by plasma-based accelerators. The smallest lasing wavelength was observed by the SIOM group, 27 nanometers, but more than an order of magnitude in photon energy still remains...
Plasma accelerators offer orders of magnitude more rapid acceleration,
and in turn can be used to reduce the size of accelerators
significantly. The experimentally obtained electron beam quality closes
the gap to conventional linacs and has now reached levels where first
free-electron lasing becomes possible. However, advanced plasma
wakefield accelerators do also open up the possibility...
Laser wakefield electron acceleration has attracted significant attention over the last decades, due to its ability to generate acceleration gradients orders of magnitude greater than those in conventional accelerators. However, in order to realise a multi-GeV laser-driven plasma accelerator stage, the laser pulse must remain focussed through tens of centimetres of low-density plasma. Such...
Laser WakeField Acceleration (LWFA) can accelerate ultra-short electron bunches up to very high energies (from hundreds of MeV to several GeV). However, LWFA usually does not provide enough charge for most of the foreseen applications, especially if high beam quality and high energies are also required.
Recently, we have devised a novel injection scheme consisting of a solid target coupled to...
Over the past several decades, the domain of laser-plasma acceleration has witnessed remarkable progress, largely credited to the escalating potency and availability of high-power lasers. Unlike the earlier phases of research where investigations were primarily confined to singular experiments with limited parameter probing, today's experiments and simulations afford exhaustive data...
The AWAKE experiment moved successfully from proof-of-concept to an experiment with a clear scientific roadmap towards accelerating electrons suitable for particle physics applications within the next decade. The goal is to produce high-charge electron-bunches accelerated to high energies (0.5-1 GeV/m), while maintaining beam quality and to develop plasma sources scalable to 100s of meters....
EuPRAXIA@SPARC_LAB will be a new multi-disciplinary user-facility that is currently under construction at the Laboratori Nazionali di Frascati of the INFN in the framework of the EuPRAXIA collaboration.
The electrons acceleration will be provided through an X-band normal conducting linac followed by a plasma module from WakeField Acceleration (PWFA).
Downstream, the beam will drive two FEL...
The realization of the reduced cost and environmental footprint promised by plasma-wakefield-driven free-electron lasers and particle colliders requires that their luminosity and brightness be comparable to that provided by conventional RF-driven facilities. This requires operating at high repetition rates, preserving the beam's energy spread, emittance and charge, and ensuring a high...
For the last decades, the development of Laser-Plasma Accelerators (LPAs) has attracted tremendous interest thanks to the capacity of plasma to produce and sustain very high electric fields. The accelerating gradients in plasma accelerators can exceed 100 GV/m, which is three orders of magnitude larger than those obtained in metallic-cavity accelerators, thus promising very compact...
Curved plasma channels have been proposed to guide intense lasers for various applications, such as x-ray laser emission, compact synchrotron radiation, and multistage laser wakefield acceleration. In this talk, we will introduce our recent study on a carefully designed experiment showing evidences of intense laser guidance and wakefield acceleration in a centimeter-scale curved plasma...
Plasma-wakefield accelerators produce relativistic, micron-scale electron bunches. The sub-micrometer internal distribution of these bunches, which critically influences gain in free-electron lasers or particle yield in colliders, has proven elusive to characterize. Through analysis of multi-spectral images of coherent optical transition radiation (COTR) that laser-wakefield-accelerated...
Preserving the quality of a positron beam in plasma-based accelerators, where a wakefield suitable for positron transport and acceleration is generated by an electron filament, poses significant challenges. The wakefields are nonlinear in the transverse direction and non-uniform in the longitudinal direction, leading to potential degradation of the beam quality. Maintaining high beam quality...
The FACET-II facility at SLAC National Accelerator Laboratory conducts a broad science program based on the interaction of low-emittance high-current 10 GeV electron beams with lasers, plasmas and solids. FACET-II operates as a National User Facility while engaging a broad User community to develop and execute experimental proposals that advance the development of plasma wakefield...
Recent progress in laser and accelerator technology opens new possibilities to investigate the largely unexplored strong-field quantum electrodynamics (SFQED) regime where electron-positron pairs can be created directly from light-vacuum fluctuations. When a high charge, ultra-relativistic electron beam collides with a solid density plasma, the beam self-fields are reflected, partly or fully,...
Because the brightness delivered by coherent light sources - such as free electron lasers (FELs) - grows with the interaction distance, they can be several km long (e.g., LCLS). Making FELs more compact while keeping their brightness, could open unprecedented research and applications to university-scale laboratories. Here, compact plasma accelerators could play a major role, but so far they...
Nanophotonic laser acceleration is a fast-evolving, emerging field aimed at providing a solution to the miniaturization of electron accelerators, down to the chip-scale. Although the average gradients are still limited by the material breakdown threshold (up to ~10 GV/m), this technology currently already offers acceleration of superb-quality single-electron pulses (normalized emittance ~100...
High-energy, spin-polarized particles are of great interest for a variety of applications like deep-inelastic scattering for the investigation of the proton nuclear structure or fusion, where the use of polarized reactants can increase the fusion cross-section. Acceleration of such particles via laser-plasma interaction can prove to be difficult, as the target needs to be pre-polarized. This...
Currently, the 10 PW experimental area is under commissioning with the first shot being fired on April 13. The experimental campaign started at the end of last year when the 10 PW laser beam was delivered to the interaction chamber with the short focal parabolic mirror. The laser is a Ti:sapphire system with a central wavelength of 810nm and a pulse duration of about 24fs. The best laser spot...
Recent developments at the high-power laser facility DRACO-PW enabled the production of polychromatic proton beams with unprecedented stability. This allowed the first in vivo radiobiological study to be conducted using a laser-driven proton source. Yet, the ability to achieve energies beyond the 100 MeV frontier is matter of ongoing research, mainly addressed by exploring advanced...
The repeated achievement of fusion ignition on the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in the U.S. has demonstrated more energy generated out of the plasma than was delivered by the lasers, thus establishing the basic scientific feasibility of harnessing fusion in the laboratory as an energy source. Fusion energy may be the ultimate clean and nearly...
Construction of a Higgs factory is the top priority for particle physics in the next decades, but the costs are prohibitively high. Plasma-wakefield accelerators (PWFAs) promise to drastically reduce the footprint and therefore the cost of such machines. However, while progress on electron acceleration is rapid, positron acceleration in plasma remains challenging. We propose a linear-collider...
In this talk, we will discuss the European Strategy for Particle Physics Accelerator R&D Roadmap and the activities under plasma accelerators. The agreed activities in this area over the next few years will be discussed.
New concepts for particle acceleration, generation, and focusing at ultra high acceleration gradients (GeV/m and beyond) have the potential to enable future e+e- and γ − γ colliders to and beyond 15 TeV energies. In addition to proven high gradient and ultra-bright beam generation, these systems have the potential to increase luminosity per unit beam power via short beams, for practical energy...
Laser Plasma Accelerators (LPA) are changing the scientific and societal landscape. Opening new hopes for high energy physics, offering alternative to synchrotron light sources with the recent demonstration with LPA’s based Free Electron Radiation, and delivering particle and radiation beams for medical and security applications, they are among the most innovative tools of modern sciences....
