S5.2: Novel sources: FEL/Laser/Plasma channels

187. SPARC_LAB recent results and future perspectives

Massimo Ferrario (LNF)

29/09/2016, 16:50

The SPARC_LAB test facility hosts a 150 MeV high brightness electron beam injector, which drives a FEL source, a THz radiation user beam line and an X-ray Thomson backscattering experiment. A particle driven plasma acceleration (PWFA) experiment is also under way. In parallel to that a 200 TW laser is linked to the linac and is devoted to explore laser-matter interaction, in particular with...

184. The SPARC_LAB Thomson source upgrade

Cristina Vaccarezza (LNF)

The SPARC_LAB Thomson source is a compact X-ray source based on the Thomson backscattering process. The electron beam energy ranges between 30 and 150 MeV, the electrons collide head-on with the Ti:Sapphire FLAME laser pulse the energy of which ranges between 1 and 5 J with pulse lengths in the 25 fs–10 ps range, providing an X-ray energy tunability in the range of 20–500 keV. After the second...

170. Development of optical resonant cavities for laser-Compton scattering

Oral presentation

The power enhancement by an optical resonant cavity is a novel method to achieve intense laser pulses for laser Compton scattering, however, it requires high precision control of the optical path to keep it on the resonance. We have beeｎ developing a new scheme to avoid this difficulty using a feedback free optical cavity with self-reconating scheme. In this talk, we report the status of...

35. Observation of elastic photon-photon scattering events using collider based on Compton gamma sources.

We present the design of a photon-photon collider based on Compton gamma sources for the observation of elastic γγ scattering. Two symmetric relativistic electron beams produce two primary gamma rays through Compton back scattering with two high energy lasers. The elastic photon-photon scattering is analysed by start-to-end simulations from the photocathodes to the detector. A new Monte...

20. Plasma-discharge undulator

The plasma wake-field acceleration (PWFA) is the promising type of acceleration, that recently had shown not only ability to produce a high energy beams at short distance, but also increasing quality of the beam in terms of energy spread, emittance and stability. Increasing quality of the PWFA beams opes for us an opportunity to create a compact FEL type sources of radiation. In this work we...

21. Betatron radiation from electrons accelerated in laser-produced plasma channels

Alessandro Curcio (LNF)

The betatron radiation from electrons accelerated in laser-produced plasma channels typically extends in the X-ray region, with a broad synchrotron-like incoherent spectrum. Nevertheless the radiation spectrum and the degree of coherence of the betatron radiation can be efficiently modified according to different laser-plasma interaction schemes. The betatron radiation seems to be a good...
