“…These magnetrons can be synchronized together and can be "phase locked" to a desired phase with the objective of getting a higher total power output at potentially lower cost. Phase locking is used in many applications [1][2][3][4][5] ranging from radar systems to materials processing. The idea is to minimize cost, to take advantage of lower power devices, and to achieve high efficiency.…”

“…Therefore, there is a need to develop a new method for phase control of magnetrons that can take advantage of their high efficiency. The simulation work presented in this work will not cover phase control of multiple magnetrons, which is a technique broadly covered in the literature; [1][2][3][4][5][8][9][10][11][12][13][14] while it will focus on the phase control of the oscillations of a single magnetron device by using a combination of a modulated, addressable, controlled electron source 15,16 and a continuous current source.…”

Phase-control of a magnetron is studied via simulation using a combination of a continuous current source and a modulated current source. The addressable, modulated current source is turned ON and OFF at the magnetron operating frequency in order to control the electron injection and the spoke phase. Prior simulation work using a 2D model of a Rising Sun magnetron showed that the use of 100% modulated current controlled the magnetron phase and allowed for dynamic phase control. In this work, the minimum fraction of modulated current source needed to achieve a phase control is studied. The current fractions (modulated versus continuous) were varied from 10% modulated current to 100% modulated current to study the effects on phase control. Dynamic phase-control, stability, and start up time of the device were studied for all these cases showing that with 10% modulated current and 90% continuous current, a phase shift of 180 can be achieved demonstrating dynamic phase control.
