Abstract
The effects of atomic number (Zn) and operating pressure (P0) of different filling gases on soft X-ray yield (Ysxr) from PF1000 are studied through numerical experiments using the modified version of the Lee model code (RADPFV5.015b). In these numerical experiments, Hydrogen (H2), Deuterium (D2), Deuterium-Tritium (D-T), Helium (He), Nitrogen (N2), Oxygen(O2) and Argon (Ar) are used over the range of 4.0 – 0.1 Torrof P0 as the filling gases. Optimum P0 at which Ysxr becomes maximum is obtained through numerical experiments for eachgas. The number density (ni), percentage of input energy into the pinch (EINP), speed factor (SF), maximum tube voltage (Vmax), pinch temperature (Tpinch), minimum pinch radius (rmin) and pinch column length (zmax) are computed at the optimum P0 of each gas to realize the corresponding plasma behavior of the PF1000 device.
