Characterization of the stability and dynamics of a laser-produced plasma expanding across strong magnetic field
Weipeng Yao, Julien Capitaine, Benjamin Khiar +5
Magnetized laser-produced plasmas are central to many new studies in laboratory astrophysics, inertial confinement fusion, and industrial applications. Here we present the results…
On the growth of the thermally modified non-resonant streaming instability
Alexis Marret, Andrea Ciardi, Roch Smets +1
The cosmic rays non-resonant streaming instability is believed to be the source of substantial magnetic field amplification. In this work we investigate the effects of the ambient…
A "lighthouse" laser-driven staged proton accelerator allowing for ultrafast angular and spectral control
VojtÄch Horný, Konstantin Burdonov, Alice Fazzini +12
Compact laser-plasma acceleration of fast ions has made great strides since its discovery over two decades ago, resulting in the current generation of high-energy ($\geq 100\,\rm M…
Direct measurement of non-thermal electron acceleration from magnetically driven reconnection in a laboratory plasma
Abraham Chien, Lan Gao, Shu Zhang +24
Magnetic reconnection is a ubiquitous astrophysical process that rapidly converts magnetic energy into some combination of plasma flow energy, thermal energy, and non-thermal energ…
High-flux neutron generation by laser-accelerated ions from single- and double-layer targets
VojtÄch Horný, Sophia N. Chen, Xavier Davoine +3
Contemporary ultraintense, short-pulse laser systems provide extremely compact setups for the production of high-flux neutron beams, such as those required for nondestructive probi…
Optimizing laser coupling, matter heating, and particle acceleration from solids using multiplexed ultraintense lasers
Weipeng Yao, Motoaki Nakatsutsumi, Sébastien Buffechoux +20
Realizing the full potential of ultrahigh-intensity lasers for particle and radiation generation will require multi-beam arrangements due to technology limitations. Here, we invest…
A Comprehensive Characterization of the Neutron Fields Produced by the Apollon Petawatt Laser
Ronan Lelièvre, Weipeng Yao, Tessa Waltenspiel +13
Since two decades, laser-driven neutron emissions are studied as they represent a complementary source to conventional neutron sources, with further more different characteristics…
Characterization and performance of the Apollon main short-pulse laser beam following its commissioning at 2 PW level
Weipeng Yao, Ronan Lelièvre, Itamar Cohen +43
We present the results of the second commissioning phase of the short-focal-length area of the Apollon laser facility (located in Saclay, France), which was performed with the main…
On the generation of astrophysically-relevant intermittent magnetic turbulence in the laboratory
Itamar Cohen, Weipeng Yao, Archie F. A. Bott +18
Intermittent magnetic turbulence, namely the presence of non-ordered and clusterized fields, is a ubiquitous phenomenon in space and astrophysical plasmas. It is currently understo…
Quantitative feasibility study of sequential neutron captures using intense lasers
VojtÄch Horný, Sophia N. Chen, Xavier Davoine +2
Deciphering the conditions under which neutron captures occur in the Universe to synthesize heavy elements is an endeavour pursued since the 1950s, but that has proven elusive up t…
Young Stars and their Variability with LSST
Rosaria Bonito, Patrick Hartigan, Laura Venuti +35
Young stars exhibit short-term photometric variability caused by mass accretion events from circumstellar disks, the presence of dusty warps within the inner disks, starspots that…
First demonstration of multi-MeV proton acceleration from a cryogenic hydrogen ribbon target
Stephan D. Kraft, Lieselotte Obst, Josefine Metzkes-Ng +9
We show efficient laser driven proton acceleration up to 14MeV from a 50 m thick cryogenic hydrogen ribbon. Pulses of the short pulse laser ELFIE at LULI with a pulse length of…
Proton Imaging of High-Energy-Density Laboratory Plasmas
Derek B. Schaeffer, Archie F. A. Bott, Marco Borghesi +8
Proton imaging has become a key diagnostic for measuring electromagnetic fields in high-energy-density (HED) laboratory plasmas. Compared to other techniques for diagnosing fields,…
Generic method to assess transmutation feasibility for nuclear waste treatment and application to irradiated graphite
Mathieu Rasson, Julien Fuchs, Grégoire Augé +2
Graphite-moderated nuclear reactors have already produced more than 250000 tons of irradiated nuclear graphite, or i-graphite, world-wide. The sustainability of this technology rel…
Enhancement of the non-resonant streaming instability by particle collisions
Alexis Marret, Andrea Ciardi, Roch Smets +2
Streaming cosmic rays can power the exponential growth of a seed magnetic field by exciting a non-resonant instability that feeds on their bulk kinetic energy. By generating the ne…
