Abstract

The Isis and Wave plasma simulation codes were used to examine the disruption of e⁺e^- beams. Qualitative agreement was found with the results of P. Chen and K. Yokoya (1988) in all three of the disruption regimes (weak focusing, transition, and confined). Quantitatively, the present results for H_D at A =0 are higher than those of R. Hollebeek (1981) and W.M. Fawley, and E.P. Lee (1987) and higher than the highest curves of Chen and Yokoya (A=0.05). However, H_D remained finite at A=0 in simulation, contrary to the prediction of Chen and Yokoya. A possible explanation for the quantitative differences between the present simulations and those of others is the low level of approximation in the present codes
