Experimental mitigation of fast magnetic reconnection in multiple interacting laser-produced plasmas

Autor: Bolaños, S., Smets, R., Courtois, C., Blanchot, N., Boutoux, G., Cayzac, W., Chen, S. N., Denis, V., Grisollet, A., Lantuejoul, I., Deroff, L. Le, Riquier, R., Vauzour, B., Fuchs, J.

The meeting of astrophysical plasmas and their magnetic fields creates many reconnection sites. We experimentally compare the reconnection rate of laser-driven magnetic reconnection when it takes place at a single site and multiple sites. For a singl

Accounting for speckle scale beam-bending in classical ray tracing schemes for propagating realistic pulses in indirect drive ignition conditions

Autor: Ruyer, C., Loiseau, P., Riazuelo, G., Riquier, R., Debayle, A., Masson-Laborde, P. E.

We propose a semi-analytical modeling of smoothed laser beams deviation induced by plasma flows. Based on a Gaussian description of speckles, the model includes spatial, temporal and polarization smoothing techniques,through fits issued from hydrodyn

Laboratory evidence of the halting of magnetic reconnection by a weak guide field

Autor: Bolanos, S., Smets, R., Chen, S. N., Grisolet, A., Filippov, E., Henares, J. L, Nastasa, V., Pikuz, S., Riquier, R., Safranova, M., Severin, A., Starodubtsev, M., Fuchs, J.

Magnetic reconnection occurs when two plasmas having co-planar but anti-parallel magnetic fields meet. At the contact point, the field is locally annihilated and the magnetic energy can be released into the surrounding plasma. Theory and numerical mo

Laboratory unravelling of matter accretion in young stars

Accretion dynamics in the forming of young stars is still object of debate because of limitations in observations and modelling. Through scaled laboratory experiments of collimated plasma accretion onto a solid in the presence of a magnetic field, we
