Plasma confinement is the most important issue in nuclear fusion research. Among all the confinement techniques magnetic confinement is most popular across the globe. We have successfully accomplished a plasma gun which is capable of producing moving plasma. This plasma gun is a compact and effective device. The density of plasma is of the order of 10 16 m -3 for discharging potential 1kV and ambient pressure 0.2 mb. It is observed that in the presence of magnetic field 250 Gauss the plasma parameters are modified. The pulse width of pulse forming network (PFN) associated with gun is 140 μs.

“…To get a flat-top current, a group of capacitors or compensators [8]- [10] are widely used in EML by setting different triggering times. There are some problems in the scheme of capacitors, such as the limited flexibility and the weak adjustability of the circuit (e.g., L and C are fixed), which leads to inconvenience in practical applications, while the scheme of the CPA has a lot of flexibility, such as the rotation speed, the excitation current, and the firing angle of thyristor.…”

Capacitor banks are used to provide a high pulsed power in traditional electromagnetic launch systems, but the large volume of these capacitors greatly limits the movability of the system; meanwhile, more and more applications require a system with significantly higher energy storage density. Rotation machines that can quickly convert rotational kinetic energy into high-current electrical energy have been designed and simulated. These generators are referred to as pulsed alternators. The shape of the high current pulse can be controlled by the triggering time of rectifiers. The direct-quadrature, or Park's, transformation is used to model a generator for simulation. The pulsed alternator consists of four stator phases, a compensated device, and field winding on the rotor all coupled together electromagnetically, and the theory is based on the standard threephase Park's transformation and extends to six-phase systems to make analysis of the four-phase air-core alternator that has a compensation device. After modeling the compensator, we obtain the transformed stator-voltage equations and the flux-linkage current relationship. A method is presented in which the pulsed alternator can be accurately modeled and used to numerically analyze the basic principle of a passive compensator. Finally, we optimize the current using the genetic algorithm. It is shown that this method can simplify the calculation, accurately predict the performance of the system, and provide guidance on the design of the prototype.
