Runaway electron induced explosions of graphite; modeling versus controlled DIII-D experiments
T. Rizzi, A. Kavroulakis, S. Ratynskaia +10
The state-of-the-art concerning the modeling of the thermomechanical response of graphite to runaway electron (RE) impact is based on one-way coupled linear thermoelasticity combin…
Optimization of the characteristics of a relativistic electron beam based on laser wake-field acceleration using a non-symmetric gas target profile
D. Mancelli, G. Andrianaki, I. Tazes +8
We demonstrate a high-energy, high-charge, electron source produced by the irradiation of a novel gaseous target by an ultra-intense femtosecond laser pulse. By exploiting a nonsym…
Laser-driven ion acceleration in long-lived optically shaped gaseous targets enhanced by magnetic vortices
I. Tazes, S. Passalidis, G. Andrianaki +11
This research demonstrates high-repetition-rate laser-accelerated ion beams via dual, intersecting, counterpropagating laser-driven blast waves to precisely shape underdense gas in…
Narrowband gamma-ray radiation generation by acoustically driven crystalline undulators
Konstantinos Kaleris, Evaggelos Kaselouris, Vasilios Dimitriou +7
In this paper we present a novel scheme for the controlled generation of of tunable narrowband gamma-ray radiation by ultra-relativistic positron beams inside acoustically driven p…
