The INTI plasma focus machine is a 3 kJ Mather type plasma focus
machine,powered by a single Maxwell capacitor. The system produces
remarkable consistent focusing action in neon, making it a suitable source for
the production of high energy photons, electrons, ions and neon soft x-rays
(SXR) [1, 2]. The aim of this paper is to optimise the neon SXR yield of the
INTI plasma focus machine operated at 12 kV by parametrically, changing the
anode dimensions (radius and length) using the Lee Model Code (version
RADPFV5.15dd). Results of the optimisation procedures resulted in a neon
SXR yield of 6.47 J at 2.5 torr and 12 kV, with a shorter length and a fatter
anode radius of 7.9 cm and 1.2 cm respectively. This gives an improvement in
the neon SXR yield of 40% when compares to neon SXR yield of 2.74 J at 2.5
torr 12 kV with the present
