Microwave applications which requires high power gave raise to need for magnetrons which can generate high power and resist this power. The invention of relativistic magnetrons met that requirment in some extent. However, their inherent pulse-shortening issue limits the obtained energy from that kind of magnetrons. In order to compansate the effects of that problem, the start-up time of magnetrons should be reduced. By this way, the energy in one pulse can be increased. In the literature, there are some methods that hasten the start-up of magnetrons. This work compares some of those methods via simulations that are carried on the relativistic A6 magnetron. In addition, from the results of the simulations an input lumped model for magnetrons is suggested and possible physical implications of that model are explained.
