Reversed field pinch (RFP) and ultralow safety factor plasma experimen
tal performances with pulsed discharge cleaning and siliconization on
SWIP-RFP device are presented. The wall siliconization was performed b
y using the device discharges. The experimental results with siliconiz
ation in RFP devices showed that the impurity concentrations were decr
eased in the plasma and better plasma parameters were obtained in the
device.
