Motion and Collision of Plasma Blobs Produced by Giant Pulse Laser in a Transverse Magnetic Field

Abstract

The properties of plasma created by the 200 MW giant pulse ruby laser irradiation on the lithium plate were investigated. Measurements of the variation of the shape and size of the plasma blob with and without the existence of the uniform magnetic field, its density, temperature, pressure, velocity of the motion and the electric field due to the charge separation were made. The phenomena occurring at the head-on collision of two blobs across the uniform magnetic field were also investigated and confirmed that the electric field could be canceled out at the colliding region.
