Abstract

Spatially resolved atomic and ionic emission has been measured in a FAPES source at radiofrequency (rf) powers ranging between 10 and 100w. The degree of ionization was spatially dependent, with maxima adjacent to the centre electrode and graphite cuvette wall. Temporally resolved atomic and ionic emission have also been measured in a newly designed FAPES source, and the temporal ionization behaviour of Mg, Cd, Fe, Zn and Cr was derived from these measurements.
