The first results of reversed field pinch (RFP) and ultra low safety f
actor (ULQ) plasma experiments with siliconization on SWIP-RFP device
are presented in this paper. The siliconization decreases the impurity
concentrations in the plasma and increases the configuration sustainm
ent time. Ion temperature has been estimated with the CV line of the v
isible light spectra and the broadening of CIII lines in vacuum ultrav
iolet (VUV) region. The anomalous ion hearing as well as the anomalous
resistance were observed.
