Reflector and Cavity

The top of the reflector contains two rectangular slots which admit microwave energy into the cavity. The slots are fed by one 1800 W, 2450 MHz magnetron located in the top half of the lamp enclosure and connected to the cavity by a waveguide launcher.

Lamp Bulb

The lamp bulb (Figure 3) is made of quartz and has a tapered shape which optimizes its UV, thermal, and microwave properties. The short quartz stubs at either end of the

15.3cm (6") bulb provide mechanical support for quick mounting into spring-loaded receptacles at the cavity ends. They are not electrodes and have no electrical function.

Figure 3. Lamp Bulb

Access to the cavity for changing the bulb or routine cleaning of the bulb and reflector is easily accomplished by removing the screws which secure the screen assembly to the bottom of the lamp. This procedure is explained in detail in Chapter 6, “Maintenance”. The fine mesh screen must be intact and firmly secured to the lamp if the system is to work properly and safely. The RF leakage interlock automatically shuts the system off if excess microwave energy passes through the screen.
