Hydrodynamic acceleration of particles in pinches with a longitudinal magnetic field

The problem on the production of non-linear necks, from which plasma jets with accelerated particles are pressed out, in the plasma pinch, is considered. The energy spectrum of these particles in the non-relativistic case describes well the spectrum of deuterons accelerated in laboratory pinches and in the relativistic case this spectrum is close enough to the observed spectrum of the galactic cosmic rays. The given work appears to be the continuation of this cycle of investigations and the non-relativistic pinch with longitudinal magnetic field, the account of which complicates the problem, but on the whole, leads to similar results and spectrum which in the limit of minor longitudinal field has the exponential form, is considered
