Paper Abstract

For study the mechanism of formation of self-generated magnetic field and proton generation in laser plasma interaction. This article based on the Maxwell’s equation applies the theoretical analysis and numerical simulation, the studied physical processes of self-generated magnetic field and proton acceleration in the interaction between ultra short laser pulse and plasma concave target, discussed provided the time evolution relationship of the distribution of self generated magnetic field induced by the non-parallel property of the temperature gradient and density gradient and proposed the laser-driven proton acceleration in plasma concave target irradiated by ultra short laser pulses with relativistic intensities. The results show that when laser injected the plasma concave target. The self-generated magnetic is generated on the surface of the plasma. Because of the nonparallel density gradient and the temperature gradient, this magnetic field considerably affects the processes of the absorption of laser energy, heat transmission and proton acceleration. Further research on this problem has significant potential applications in the realization of inertial confinement fusion, medical diagnosis, treatment and so on.
