  A simple table-size ECR plasma generator operates in the ATOMKI without axial
magnetic trap and without any particle extraction tool. Radial plasma
confinement is ensured by a NdFeB hexapole. The table-top ECR is a simplified
version of the 14 GHz ATOMKI-ECRIS. Plasma diagnostics experiments are planned
to be performed at this device before installing the measurement setting at the
big ECRIS. Recently, the plasma generator has been operated in pulsed RF mode
in order to investigate the time evolution of the ECR plasma in two different
ways. (1) The visible light radiation emitted by the plasma was investigated by
the frames of a fast camera images with 1 ms temporal resolution. Since the
visible light photographs are in strong correlation with the two-dimensional
spatial distribution of the cold electron components of the plasma it can be
important to understand better the transient processes just after the breakdown
and just after the glow. (2) The time-resolved ion current on a specially
shaped electrode was measured simultaneously in order to compare it with the
visible light photographs. The response of the plasma was detected by changing
some external setting parameters (gas pressure and microwave power) and was
described in this paper.
