In this paper we present the thermal simulation results of a 300 kW L-band tunable pulsed magnetron using thermo-electric module of commercial software ANSYS Multiphysics. The resonant structure of this magnetron is a double ring hole and slot type structure with oxide coated cathode. The heater voltage and current are in the range of 9–10 V and 15–16 A respectively. The electrical load in term of heater voltage has been applied between both terminals of the heater. It is predicted by simulation that the total power dissipation in the magnetron anode block can be easily managed by the forced air cooling, and rise in temperature will not affect the frequency of oscillation of magnetron.

摘要

In this paper we present the thermal simulation results of a 300 kW L-band tunable pulsed magnetron using thermo-electric module of commercial software ANSYS Multiphysics. The resonant structure of this magnetron is a double ring hole and slot type structure with oxide coated cathode. The heater voltage and current are in the range of 9–10 V and 15–16 A respectively. The electrical load in term of heater voltage has been applied between both terminals of the heater. It is predicted by simulation that the total power dissipation in the magnetron anode block can be easily managed by the forced air cooling, and rise in temperature will not affect the frequency of oscillation of magnetron.
