High-charge collimated and energy-selected laser-driven MeV electron beams produced by magnetic selection
I. Cohen, I. Slabu, Q. Peysson +16
We have developed a compact passive energy-selector for MeV-range electrons produced by irradiating solid targets by ultra-intense short-pulse lasers. The device allows for generat…
Simultaneous PW-scale laser driven MeV X-ray and neutron beam characterization for dual radiography capability
I. Cohen, W. Yao, N. Mirkovic +28
Laser-driven, high-brilliance secondary sources (electrons, ions, neutrons, X-rays) open new perspectives for compact material probing and imaging of high-speed events. A key advan…
Experimental evidence for coronal mass ejection suppression in strong stellar magnetic fields
S. N. Chen, K. Burdonov, W. Yao +10
Solar coronal mass ejections (CME) are routinely observed, but as of yet there exist few convincing detections of stellar CMEs. A reason for this could be the stronger magnetic fie…
Investigation of Laser Plasma Instabilities driven by Coupled High-Power Laser Beams in Magnetized Underdense Plasmas
C. L. C. Lacoste, D. Oportus, J. Béard +10
Stimulated Brillouin and Raman scattering (SBS and SRS) are instabilities that affect the propagation of high-power lasers in plasmas. The latter is further affected by Cross-Talk…
Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…
