Abstract

The megawatt pulsed power magnetron operating in the L-band was designed based on magnetrons produced in the past at Kubara Lamina. Unlike its predecessors, it is characterized by much higher operating parameters: supply voltage and anode current, which translates into an increase in the obtained output power. The magnetron was designed using software for numerical simulations of the interaction of an electric charge with an alternating electromagnetic field (Particle in Cell - PiC). Aspects such as microwave matching of individual components of the device and thermal resistance of the entire system, including the appropriate type of cooling, have also been subjected to numerical analysis. In order to obtain the proper parameters of power supply of the tube, a dedicated impulse modulator powered by supercapacitors was build. The modifications allowed to obtain a power signal with a sharp and stable edge and a pulse length of the length of single microseconds. Obtaining the optimal power source had a key impact on the tube’s operation. The measurements of tube output power in the waveguide system with dummy load were carried out, during which the output power of the megawatts range was obtained. This magnetron is a tube with the highest output power among the microwave tubes ever designed in the Kubara Lamina Company and probably throughout Poland.
