Abstract:
A new regime in the expansion of a laser plasma into vacuum has been studied. In this regime, the number of fast ions increases sharply, and a thin shell containing up to half the total energy and a quarter of the total number of particles forms at the vacuum boundary of the plasma. The motion of this shell is stable. This transformation of the ion distribution function is achieved by applying microsecond CO, laser pulses to cylindrical and spherical targets. A model for the compression of the ions of the plasma corona into the shell is proposed. This model is based on the time variation of the absorption of radiant energy, the change in the flux of particles from the target, and the collective interaction of the ions in the course of the expansion. The target geometry plays an important role in the appearance of this shell structure in the plasma corona.
