Microwave head - compact size
This new head includes a water cooled magnetron and the filament transformer. An isolator with its reflected power crystal detector is connected to the microwave head. Quick release connectors for water cooling and high voltage are used on both the power supply and the microwave head. A water flow meter is connected at the exit of the cooling circuit of the isolator; this water sensor acts as an interlock which will completely shut down the microwave generator if not enough water flow is sensed.
