We describe the generation of plasma filaments for application in plasma-based particle accelerators. The complete characterization a filament generated by low-energy self-guided femtosecond laser pulse is studied experimentally and theoretically low-pressure nitrogen gas environment. For this purpose, we adopted spectroscopic methodology to measure density electron temperature. In addition this, also employed side-imaging technique retrieve column sizes (length diameter). measurements show...
<title>Abstract</title> Resonances play a crucial role in media sustaining oscillatory phenomena, such as plasmas. Normally, the frequency of external forces delivering energy is chosen to be out tune with respect natural plasma electron frequency, so avoid resonances leading development deleterious instabilities. However, context wakefield acceleration, can exploited generate large-amplitude wakefields, using train relativistic particle bunches content close accelerate trailing bunch. We...
Abstract Novel particle accelerators based on plasma technology allow a drastic reduction in size, due to the high accelerating field established inside plasmas, which are created and confined by specific devices. Plasma Wakefield Acceleration experiments performed at SPARC_LAB test facility (Laboratori Nazionali di Frascati - INFN) using gas-filled capillaries, formation is achieved ionizing hydrogen gas through voltage pulses. In this work, characterization of plasma-discharge capillaries...
We present a new approach that demonstrates the deflection and guiding of relativistic electron beams over curved paths by means magnetic field generated in plasma-discharge capillary. experimentally prove is much less affected beam chromatic dispersion with respect to conventional bending magnet and, support numerical simulations, we show it can even be made dispersionless employing larger discharge currents.

Abstract Plasma wakefield acceleration revolutionized the field of particle accelerators by generating gigavolt-per-centimeter fields. To compete with conventional radio-frequency (RF) accelerators, plasma technology must demonstrate operation at high repetition rates, a recent research showing feasibility megahertz levels using an Argon source that recovered after about 60 ns. Here we report proof-of-principle experiment demonstrates recovery Hydrogen sub-nanosecond timescale. The result is...
The space-charge field of a relativistic charged bunch propagating in plasma is screened due to the presence mobile charge carriers. We experimentally investigate such screening by measuring effect dielectric wakefields driven uncoated capillary where confined. show that screens and therefore suppresses when distance between surface much larger than skin depth. Before full reached, effects are present simultaneously.
Plasma wakefield acceleration represented a breakthrough in the field of particle accelerators by pushing beams to gigaelectronvolt energies within centimeter distances. The large electric fields excited driver pulse plasma can efficiently accelerate trailing witness bunch paving way toward realization laboratory-scale applications like free-electron lasers. However, while accelerator size is tremendously reduced, upstream and downstream it are still handled with conventional magnetic optics...

Dielectric capillaries are widely used to generate plasmas for plasma wakefield acceleration. When a relativistic drive bunch travels through capillary with misaligned trajectory respect the axis, it is deflected by effect of dielectric transverse wakefields drives. We experimentally show that deflection increases along and larger misalignment, we investigate decay measuring on front trailing bunch. discuss implications design accelerator based capillaries.
