Abstract
The six-phase Lee Model Code is used to fit the computed current waveform to the measured
waveform of the INTI Plasma Focus (PF;2.2 kJ at 12 kV), a T2 PF device, operated as a source of
Neon soft X-ray (SXR) with optimum yield around 2.5 - 3 Torr of neon. The characteristic He-like
and H-like neon line SXR pulse is measured using a pair of SXR detectors with selected filters
that, by subtraction, have a photon energy window of 900 to 1550 eV covering the region of the
characteristic neon SXR lines. The aim of this paper is to investigate the correlation between the
time histories of the measured Neon soft X-ray pulse and the reflected shock phase of the
computed current waveform which has been fitted to the measured current waveform. Results
shows that the characteristic neon SXR measured at 3.17 J with a pulse duration of 249 ns starts
typically after the radial inward shock phase and increases in magnitude few ns before the pinch
phase. It tails unto the first anomalous resistance, and decays at the second anomalous resistance.
