The Lee model code is used in numerical experiments for characterizing andoptimizing neon soft X-ray (Ysxr) yield of UNU/ICTP PFF machine operated at 14kV and 30 micro F. The neon Ysxr yield of the dense plasma focus device isenhanced by reducing static inductance (L0) and anode length (z0) along withincreasing anode radius (a) and cathode radius (b), keeping their ratio (c =b/a) constant at 3.368. At the optimum combination of the electrodes geometryand static inductance, the maximum computed value of neon Ysxr yield is 63.61 Jat operating pressure 3.3 Torr with corresponding X-ray yield efficiency 2.16%,while the end axial speed becomes 6.42 cm/s. This value of neon Ysxr yield istwelve to thirteen times higher than the measured value (5.4 J) at 3.0 Torr. Itis also found that this neon Ysxr yield is improved around seven times frompreviously computed value (9.5 J) at 3.5 Torr for optimum anode configurationof this machine. Our obtained results of neon Ysxr yield are also compared withthe computed results of AECS-PF2 machine operated at 15 kV and 25 micro F andis found that our results are about three times better than that from theoptimized AECS-PF2 at L0 = 15 nH.
