Abstract:

Contents computer simulation of bounded plasma systems, with external circuits, is discussed in considerable detail Artificial cooling of trapped electrons in bounded simulations was observed and is now attributed to noiseless injection the cooling does not occur if random injection is used The collector and source sheaths at the boundaries of warm plasma are treated in detail, including ion reflection and secondary electron emission at the collector The Kelvin Helmholtz instability is observed in a self-consistent magnetized sheath, producing long-lived vortices which increase the particle transport to the wall dramatically The ES2 Users Manual - Version 1 has been issued Addition of electron neutral elastic collisions is introduced Implicit particle simulation of velocity space transport and self-consistent electric potentials in magnetized plasmas TESS code is described in detail and Dynamic dimensioning with heap management is described in detail.
