Abstract—The dynamics of an initially uniform plasma heated by a microsecond relativistic electron beam in
a solenoid are considered. A set of one-dimensional equations of motion, continuity, and heat transport for a
plasma in a long solenoid is used to solve the problem. The initial and boundary conditions of the numerical
model correspond to those in the GOL-3 device. A comparison of the data obtained from the model with exper-
imental results shows that, during beam injection, the plasma thermal conductivity is suppressed by two or
threeorders of magnitude. In the plasma-cooling stage, the plasma temperature decay can be adequately
described in terms of classical electron heat transport onto the ends of the device. The processes of generation
and propagation of large-amplitude ion-acoustic waves are also observed.
