On the Possibility of Spontaneous Magnetic Field Observation in Turbulent Laser Plasma

摘要

It has been discussed the opportunity of the spontaneous magnetic field (SMF) observation in turbulent hot plasma which formed as the result of power laser beam interaction with porous low density matter. The sources of SMF appearance are the crossed gradients of electron pressure and plasma density, which arise in the turbulent zone and increase with its development. It has been proposed two diagnostic methods for investigation of SMF generation in turbulent laser plasma. The first method bases on the idea of the constrained orientation of magnetic moments with help of the external strong regular magnetic field (～ 0.1 MG). The second method bases on the idea of bunch electron scattering observation in the magnetic fields. The Mega Gauss SMF could effect on energy transport in laser plasma. The generation of SMF up to 100 MGs in low density substance could suppress the electron heat conductivity into the wall of cone target and improve the conditions of "dynamical confinement" of compressed DT fuel.
