  • Particle in cell simulations on the effects of electrically biased grid to the plasma parameters
    Jelić, Nikola ; Kos, Leon, 1966-
    Recently Baalrud et al [Physics of Plasmas 14 042109 (2007)] investigated a plasma under conditions of nonambipolar flow, under special plasma confinement scenario where all electrons are lost to one ... boundary and all positive ions to another boundary. More generalized scenario of ambipolar flow to different boundaries was investigated by Jelic et al. [Contrib. Plasma Phys. 43/2 111 (2003)] via developing a self consistent theoretical model for calculating the plasma potential, plasma density and electron temperature. Both approaches rely on so called zero dimensional approximation. Since the problem of ambipolar flow is an important one in space, laboratory and fusion plasmas as well as in Langmuir probe diagnostics, we employ a one-dimensional Particle in Cell (PIC) code to simulate the plasma behavior in the presence ofan electrically biased object in higher dimensionality. Simulated results agree well with theoretical predictions and experimental results, but may be considered as more reliable ones.
