Experimental study of line spectrum generation by argon dopant in DT-gas on ISKRA-5 facility

The experiments measuring the density of DT mixture compressed in indirect drive targets (X-ray targets) were conducted on the ISKRA-5 facility. The d ensity was determined from the line broadening of H- and He-like Ar doped i n DT-gas as a diagnostic substance. A series of three experiments with the X-ray targets having different shell thickness of capsule filled with DT Ar mixture were carried out. In two of the three experiments, radiation spe ctra of Ar were recorded and the density of compressed gas was determined. The analysis of the experimental results for the X-ray target with a 280-mu m diameter and a 7 mu m wall thickness revealed that the density of the co mpressed gas may be estimated as similar to 1 g/cm(3).
