Abstract :
In this paper, we report a new concept of a microwave transmitter with phase controlled magnetrons (PCM) and we also propose a new phased array system with PCMs for the SPS. In order to stabilize a frequency of magnetron and to control a phase by PCM with an injection locking technique and PLL feedback to anode current. In Kyoto University, we developed a phased array with a several PCMs with high efficiency.
