摘要: For insight into the microscopic mechanism of Z-pinch dynamic processes, a code two-dimensional particle-in-cell (PIC) simulation has been developed in cylindrical coordinates. In principle, current-carrying rarefied deuterium plasma shell simulated by means this code. Many results related to processes are obtained. They include spatio-temporal distributions electromagnetic field, current density, forces experienced ions and electrons, positions energy particles, trailing mass current. radial direction, electric magnetic exerted on electrons comparable magnitude, while mainly forces. So process, first accelerated Z direction get higher velocities; then, they driven inwards axis at same time (i.e., Lorentz forces) them. That causes separa...
