Abstract: This paper presents the design and initial operation of a double anode magnetron injection gun (MIG) for a 34GHz basic wave gyro-klystron. To accurately determine the beam characteristics of MIG, a theory model with cathode emission is built. A new computer program is employed to simulate electron and cathode emission. Simulation and measurement results indicate that magnetic field influences the beam current of MIG, and the beam current of the MIG depends on the cathode temperature and space charge effect． -
