On the wake of results obtained so far at SPARC_LAB test-facility Laboratori Nazionali di Frascati (Italy), we are currently investigating possibility to design and build a new multi-disciplinary user-facility, equipped with soft X-ray Free Electron Laser (FEL) driven by ∼1 GeV high brightness linac based on plasma accelerator modules. This study is performed in synergy EuPRAXIA study. In this paper report about recent progresses going facility.
Abstract Very high energy electron (VHEE) beams have been proposed as an alternative radiotherapy modality to megavoltage photons; they penetrate deeply without significant scattering in inhomogeneous tissue because of their relativistic inertia. However, the depth dose distribution a single, collimated VHEE beam is quasi-uniform, which can lead healthy being overexposed. This be largely overcome by focusing small spot. Here, we present experiments demonstrate means concentrating into...
The duration of incoherent XUV pulses down to the femtoseconds (fs) can be retrieved through a statistical analysis modulations on observed radiation spectrum. Uncorrelated shot-noise fluctuations in pulse temporal profile result showing multispike spectrum where spike width is inversely proportional length. In this Letter, single-shot characterization betatron emitted by fs-long, 100's MeV electron bunches undergoing acceleration, and propagating plasma wiggler was performed domain. lengths...

FLASH therapy, a novel cancer treatment technique, aims to control tumor growth, sparing the healthy tissue from radiation damage and thus increasing therapeutic ratio. Translating therapy into clinical practice, especially for treating deep-seated tumors, necessitates achieving Very High-Energy Electron (VHEE) levels within 50-250 MeV range. In 2022 Sapienza University, in collaboration with INFN, launched SAFEST project, compact C-band 100 Ultra-High Dose Rate (UHRD) source of which was...

These escaping particles identified as essential core picosecond-scale phenomena such laser-based acceleration, surface manipulation, generation intense magnetic fields and electromagnetic pulses. Increasing number facilitate late time processes in all cases. Up to now only indirect evidences these important forerunners have been recorded, thus no...
Abstract Fluid targets are attractive for laser-driven ion acceleration at high-repetition-rate laser facilities. In particular, liquid have several interesting features since they can regenerate in situ and debris-free (or little) operate a high repetition rate. Here, we report MeV-range proton by the interaction of VEGA-2 system with micrometer-thick water sheet target vacuum (10 −4 mbar) environment. The was running continuously this pressure 4 h more than 1000 shots were performed. Two...
Two-color plasma, induced by two lasers of different colors, can radiate ultra-broadband and intense terahertz (THz) pulses, which is desirable in many technological scientific applications. It was found that the polarization emitted THz depends on phase difference between fundamental laser wave its second harmonic. Recent investigation suggests chirp-induced change pulse overlap plays an important role yield from two-color plasma. However, effect chirp remains unexplored. Hereby, we...
Abstract X-ray sources have a strong social impact, being implemented for biomedical research, material and environmental sciences. Nowadays, compact accessible are made using lasers. We report evidence of nontrivial spectral-angular correlations in laser-driven betatron source. Furthermore, by angularly-resolved spectral measurements, we detect the signature spatial phase modulations electron trajectories. This allows lateral coherence function to be retrieved, leading evaluation area...

Optical vector beams have great potential in many applications, for example optical tweezers, information transmission and processing, laser surface structuring, particle acceleration, vortex dichroism spectroscopy. However, the reported terahertz (THz) spectral range are limited to exhibiting only low-order topological charges. Therefore, methodologies generate THz bearing a tailored charge highly desired.

Nowadays, plasma wakefield acceleration is the most promising technique for compact and cheap accelerators, needed in several fields, e.g., novel light sources industrial medical applications. Indeed, high electric field available structures (>100 GV/m) allows accelerating electrons at GeV energy scale a few centimeters. Nevertheless, this approach still suffers from shot-to-shot instabilities, mostly related to experimental parameter fluctuations, laser intensity density. Therefore,...
