[EDIT] My real question here is: can a magnetron from a microwave oven be used to output low power microwaves? If so, how can I achieve this? If not, what is a source for low power microwaves? In this context, low power means that I don't intend to output microwaves that are dangerous to a human being.
Is it feasible/reasonable to drive a microwave oven magnetron from a CCFL backlight driver? From what I've seen, the voltage produced by the CCFL driver should be in the ballpark what a magnetron accepts.
I want to use the radiation for measurements, so I don't need the high power a megnetron would typically produce and a lower power rating makes this feel much safer.
