- I'd like to use a small microwave oven ( will a small vacuum chamber inside)
- to generate reactive plasmas ( O2 etc) for cleaning and etching in our lab.
- The idea sort of works, but even the smallest ovens (400 Watts or so)
- generate so much heat that they tend to burn samples more than etch them...
-
- Does anyone know how to lower the power output of the magnatron, or is it
- possible at all? I'd like to cut the power to 50W or so...

- Thanks,
- Ed
