摘要：The Thailand Plasma Focus II (TPF-II) is a 3.3 kJ dense plasma focus that was developed at Walailak University, Thailand. The aims of the device is to study the production of ion beams in the keV energy range and their applications for color modification of gem stones. The high energy ion beam is produced by heating and acceleration in the pinch phase of plasma focus. The heating process is determined by the maximum electrical current, which can be optimized by variation of the system’s inductance. Lee model code was implemented to optimize the configuration of the electrodes. The current waveforms for different initial conditions were used to obtain the system’s inductance which was verified by a short circuit test. It was found that the inductance and resistance are about 153 nH and 12 mΩ, respectively.
