We investigated experimentally ion heating and the structure of the potential following compression of a plasma (n/sub 0/approx. =0.7 x 10/sup 1/2 -- 5 x 10/sup 1/2 cm/sup -/3) by a magnetic piston (H=1200 Oe, T/4=400 nsec) in a theta pinch without an initial magnetic field. We demonstrate the existence of broad spectra of ions moving in a radial direction and scattered through 45/sup 0/. A potential discontinuity of width approx.50--100 Debye lengths is formed ahead of the magnetic piston. The results do not contradict the assumption that a turbulent electrostatic shock wave exists under the conditions in question.
