“…simultaneously both by an x-ray scintillator and a CCD-X camera calibrated during a previous experiment [36], positioned at 0.7 m from the interaction point, cooled down to −30°C and shielded by a lead cage from broad-divergence bremsstrahlung. The goal was that of measuring simultaneously the spatial distribution of the radiation with the x-ray scintillator and the spectrum in single photon counting [15] mode with the CCD-X camera.…”

A new methodology able to model and reconstruct the transverse trace space of low-emittance electron beams accelerated in the bubble regime of laser-plasma interaction is presented. The single-shot measurement of both the electron energy spectrum and the betatron radiation spectrum is shown to allow a complete measurement of the transverse emittance, including the correlation term. A novel technique to directly measure the betatron oscillation amplitude distribution is described and tested at the SPARC-LAB test facility through the interaction of the ultrashort ultraintense Ti:Sa laser FLAME with a He gas-jet target. Via the exposed technique the beam transverse profile is also retrieved. From the study of the electron transverse dynamics inside the plasma bubble, the nonlinear correlation between the betatron amplitude and the divergence, i.e. the angle with respect the acceleration axis, is found. The angular distribution of the electron beam inside the bubble is retrieved. The knowledge of the trace-space density allows a more accurate measurement of the transverse emittance with respect to previous paradigms

“…An experiment was recently performed in the Frascati area [5] regarding the emission of X-rays from a solid tin target irradiated by a low energy (few mJ) femtosecond (50 fs) laser pulse (λ = 0.8 µm) propagated through air plasma filament. The goal was that to better understand the X-ray emission mechanism and to show the possibility to produce proper radiation for spectroscopic and imaging applications with a table top laser system.…”

“…Indeed, the possibility to reach power densities larger than 10 19 W/cm 2 at the femtosecond level has been exploited in many fields of research: astrophysics in the laboratory [1], high energy density experiments [2], electromagnetic wave sources [3][4][5] and novel schemes for particle acceleration [6]. The dream of a table-top accelerator, both for e − and p + , has attracted many people working in the plasma field, but, even though compact accelerating systems have been already demonstrated [7][8][9][10], the produced charged particle beams are still affected by shot-by-shot instabilities.…”

Nowadays, plasma wakefield acceleration is the most promising acceleration technique for compact and cheap accelerators, needed in several fields, e.g., novel compact light sources for industrial and medical applications. Indeed, the high electric field available in plasma structures (>100 GV/m) allows for accelerating electrons at the GeV energy scale in a few centimeters. Nevertheless, this approach still suffers from shot-to-shot instabilities, mostly related to experimental parameter fluctuations, e.g., laser intensity and plasma density. Therefore, single shot diagnostics are crucial in order to properly understand the acceleration mechanism. In this regard, at the SPARC_LAB Test Facility, we have developed two diagnostic tools to investigate properties of electrons coming from high intensity laser-matter interaction: one relying on Electro Optical Sampling (EOS) for the measurement of the temporal profile of the electric field carried by fast electrons generated by a high intensity laser hitting a solid target, the other one based on Optical Transition Radiation (OTR) for single shot measurements of the transverse emittance. In this work, the basic principles of both diagnostics will be presented as well as the experimental results achieved by means of the SPARC high brightness photo-injector and the high power laser FLAME.
