Femtosecond timing-jitter between photo-cathode laser and ultra-short electron bunches by means of hybrid compression / Pompili, Riccardo (Laboratory Nazionali di Frascati) ; Anania, M.P (Laboratory Nazionali di Frascati) ; Bellaveglia, M (Laboratory Nazionali di Frascati) ; Biagioni, A (Laboratory Nazionali di Frascati) ; Castorina, G (Laboratory Nazionali di Frascati and University of Catania) ; Chiadroni, E (Laboratory Nazionali di Frascati) ; Cianchi, A (University of Rome Tor Vergata) ; Croia, M (Laboratory Nazionali di Frascati) ; Di Giovenale, D (Laboratory Nazionali di Frascati) ; Ferrario, M (Laboratory Nazionali di Frascati) et al.
The generation of ultra-short electron bunches with ultra-low timing-jitter relative to the photo-cathode (PC) laser has been experimentally proved for the first time at the SPARC_LAB test-facility (INFN-LNF, Frascati) exploiting a two-stage hybrid compression scheme. The first stage employs RF-based compression (velocity-bunching), which shortens the bunch and imprints an energy chirp on it. [...]

500 fs Streak Camera for UV-Hard X-Rays in 1 kHz Accumulating Mode with Optical 'Jitter Free' Synchronisation / Scheidt, K ; Naylor, G A
The development at the ESRF of a jitter-free, laser triggered Streak Camera has now yielded time resolution results as short as 460 fs while operating in accumulating mode. The so-called jitter-free synchronisation between the laser light and the Streak Camera is performed through a GaAs photo-switch in a simple HV circuit that connects directly to the Streak tube's deflection plates.

Photo-cathodes for the CERN CLIC Test Facility / Chevallay, E (CERN) ; Durand, J (CERN) ; Hutchins, S (CERN) ; Suberlucq, Guy (CERN) ; Trautner, H (CERN)
Since 1993 the CLIC Test Facility (CTF) has used laser-illuminated Tellurium Alkali photo-cathodes as intense electron sources (up to 50 nC in 10 ps), for the Drive Beam of a two-beam accelerator. These cathodes have been produced and tested in our photo­emission laboratory and transported under vacuum to the CTF. [...]

EuPRAXIA@SPARC_LAB Design study towards a compact FEL facility at LNF / Ferrario, M. (Frascati) ; Alesini, D. (Frascati) ; Anania, M.P. (Frascati) ; Artioli, M. (ENEA, Bologna) ; Bacci, A.

On the wake of the results obtained so far at the SPARC\_LAB test-facility at the Laboratori Nazionali di Frascati (Italy), we are currently investigating the possibility to design and build a new multi-disciplinary user-facility, equipped with a soft X-ray Free Electron Laser (FEL) driven by a $\sim$1 GeV high brightness linac based on plasma accelerator modules. This design study is performed in synergy with the EuPRAXIA design study. [...]

$\gamma\gamma$ physics with the KLOE experiment / KLOE-2 Collaboration
The processes $e^+e^-\to e^+e^-X$, with $X$ being either the $\eta$ meson or $\pi^0\pi^0$, are studied at DA$\Phi$NE, with $e^+e^-$ beams colliding at $\sqrt{s}\simeq1$ GeV, below the $\phi$ resonance peak. [...]
