Abstract
A projectile is accelerated in a bore of a barrel by applying a plasma to the bore behind the projectile. The plasma has a tendency to occupy a volume in the bore behind a location in the bore where the plasma is applied. A magnetic field is applied to the plasma synchronously with application of the plasma to the bore for substantially preventing the plasma from flowing into the bore volume behind the location.
