• Time- and space-resolved observations of fluctuating electric fields are madeusing the plasma satellites of the Hel 492.2 nm line during art implosion phasein a small-linear theta pinch. The rapid excitation (up to - 6 kV/cm) and decayof the fluctuating fields with the frequency smaller than the electron plasma fre-quency are observed except near the center of the pi[asma colurnn. Measurementof the magnetic field B. indicates that the intense fluctuating fields are localizedin a narrow layer just behind the imploding magnetic front. From a measurementof the ion temperature, the fast ion heating and thermalization are observed inthe implosion phase. These fast heating and thermalization and the decay of thefluctuations are almost coincidertt in time.
