Numerical Experiments on Soft X-ray Emission Optimization of Nitrogen Plasma in 3 kJ Plasma Focus SY-1 Using Modified Lee Model
The X-ray emission properties of nitrogen plasmas are numerically investigated using corona plasma equilibrium model. The X-ray emission intensities of nitrogen Lya, Lyb and Hea, Heb lines are calculated. The optimum plasma temperature for nitrogen X-ray output is concluded to be around 160 eV....

| description | The X-ray emission properties of nitrogen
plasmas are numerically investigated using corona plasma
equilibrium model. The X-ray emission intensities of
nitrogen Lya, Lyb and Hea, Heb lines are calculated. The
optimum plasma temperature for nitrogen X-ray output is
concluded to be around 160 eV. The Lee model is modified
to include nitrogen in addition to other gasses (H2, D2, He,
Ne, Ar, Xe). It is then applied to characterize the 2.8 kJ
plasma focus PF-SY1, finding a nitrogen soft X-ray yield
(Ysxr) of 8.7 mJ in its typical operation. Keeping the bank
parameters and operational voltage unchanged but systematically
changing other parameters, numerical experiments
were performed finding the optimum combination of
pressure = 0.09 Torr, anode length = 7.2 cm and anode
radius = 2.58 cm. The optimum Ysxr was 64 mJ. Thus we
expect to increase the nitrogen Ysxr of PF-SY1 sevenfold
from its present typical operation; without changing the
capacitor bank, merely by changing the electrode configuration
and operating pressure. |
