Abstract

PURPOSE:To make temperatures of lamp and cavity resonator uniform by suppressing a space for insulation and a quantity of heat leaking outside through bringing a lampe house into contact thermally with the cavity resonator by way of a matter having a suitable thermal resistance. CONSTITUTION:Equivalent thermal resistances of lamp house 32, cavity resonator 36 and heat contact member 41 are indicated by 71, 72 and 77 respectively; thermal resistances on the heat flowing out of the lamp house 32 and the resonator 36 are indicated by 73 and 74 respectively; heat sources provided for the lamp house 32 and the resonator 36 are indicated by 75 and 76 respectively. There occurs a flow of heat on the thermal resistance 77 as indicated by arrow from keeping the lamp house 32 higher in temperature than the resonator 36, and the heat flows into the thermal resistance 72 from both the two. Therefore, a value of the thermal resistance 77 is set suitably, the resonator 36 is heated at even temperature from both ends and a shape of the lamp house 32 is adjusted, thereby making temperatures of both the lamp 31 and the resonator 36 uniform.
