The XUV spectra from Ag XIX of laser-produced plasma are measured. The density dependence of An= 0(4-4) transitions from Ag XIX has been studied in a density range 1017-1022 cm-3 with the collisional radiative model. The theoretical model includes the effect of cascading from n=5 states on the population of the n=4 levels. In addition, optical depth effects on the line intensities were considered. The two transitions of 4d2D5/2-4f2F7/2 and 4p2P3/2-4d2D5/2 remain close to each other and are unblended with other lines. Calculations of their radiation intensity ratio vs the electron density are performed. Electron density of laser produced plasma has been deduced from the ratio.

The quasi-stationary profiles of the impurity ionization stages in HT-6B toka-mak were determined by monitoring the VUV (vacuum ultraviolet) and visible line emissions from impurities. An impurity transport code was set up. The impurity transport coefficients and other parameters of impurities in that device were simulated and determined. From the measurement of impurity emission profiles and simulation analysis, it was concluded that the impurity confinement was improved and the impurity recycling was reduced by the slow magnetic compression. Some characteristics of impurity transport in that device were also discussed.
