1 Magnetic Reconnection and Plasma Dynamics in Two-Beam Laser Solid Interactions P. M. Nilson University of Rochester Laboratory for Laser Energetics 48th Annual Meeting of the American Physical Society Division of Plasma Physics Philadelphia, PA 30 October 3 November 2006
2 Summary A magnetic-reconnection geometry has been studied using two closely focused laser beams (10 15 W/cm 2, 1 ns) The plasma dynamics created by two heater beams at the surface of a planar solid target (Al or Au) has been studied. Observations consistent with a magnetic reconnection have been made the formation of a driven magnetic-reconnection field distribution the interaction of 0.7- to 1.3-MG magnetic fields in a reconnection layer collimated, high-velocity jet formation high electron temperature (T e = 1.7 kev) in the reconnection layer Reconnection rates predicted by the Sweet Parker model of reconnection (assuming Spitzer resistivity) are too slow to explain these observations.
