Abstract
A system is presented for the time resolution of plasma potential using gridded electrostatic analyzers. The novelty of this method is the separation of consecutive current-energy characteristic curves and their display on a CRT. Using a 20 kHz bias signal, 30–50 consecutive 25 μsec sweeps are displayed on a CRT in a 1 msec time interval. This is sufficient for the study of low frequency plasma fluctuations in transient confinement experiments. Application to the DCX-2 mirror machine is discussed.Keywords
