Abstract :
Conditions for compression of a laminar nonrelativistic dense beam by an inhomogeneous magnetic field B are investigated theoretically and numerically. A generalized Brillouin regime is defined in which an efficient beam compression may proceed according to the scaling Br=const, provided the field undergoes slow variations: adiabaticity condition. The initial density profile and radial velocity are found critical for subsequent laminarity
