Magnetic reconnection between colliding magnetized laser-produced plasma plumes.
Observations of magnetic reconnection between colliding plumes of magnetized laser-produced plasma are presented. Two counterpropagating plasma flows are created by irradiating oppositely placed plastic (CH) targets with 1.8-kJ, 2-ns laser beams on the Omega EP Laser System. The interaction region between the plumes is prefilled with a low-density background plasma and magnetized by an external...
متن کاملFast Magnetic Reconnection in High-Energy-Density Laser-Produced Plasmas1 WILLIAM FOX, Center for Integrated Computation and Analysis of Reconnection and Turbulence, University of New Hampshire Recent experiments have observed magnetic reconnection in high-energy-density, laser-produced plasma bubbles
Recent experiments have observed magnetic reconnection in high-energy-density, laser-produced plasma bubbles [1,2], with reconnection rates observed to be much higher than can be explained by classical theory. This is a novel regime for magnetic reconnection study, characterized by extremely high magnetic fields, high plasma beta and strong, supersonic plasma inflow. Reconnection in this regime...
متن کاملCharacterization of single and colliding laser-produced plasma bubbles using Thomson scattering and proton radiography.
Time-resolved measurements of electron and ion temperatures using Thomson scattering have been combined with proton radiography data for comprehensive characterization of individual laser-produced plasma bubbles or the interaction of bubble pairs, where reconnection of azimuthal magnetic fields occurs. Measurements of ion and electron temperatures agree with lasnex simulations of single plasma ...
متن کاملElectrostatic structure of a magnetized laser-produced plasma.
Measurements of the structure of the electrostatic fields produced by the expansion of a laser-produced plasma into a background magnetized plasma are presented. The three-dimensional measurements of the electrostatic field are made using an emissive probe that measures the time-varying plasma potential on two orthogonal planes, one across and one containing the background magnetic field. The i...
متن کاملScaling mechanisms of vapour/plasma shielding from laser-produced plasmas to magnetic fusion regimes
The plasma shielding effect is a well-known mechanism in laser-produced plasmas (LPPs) reducing laser photon transmission to the target and, as a result, significantly reducing target heating and erosion. The shielding effect is less pronounced at low laser intensities, when low evaporation rate together with vapour/plasma expansion processes prevent establishment of a dense plasma layer above ...
