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 User's 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.
