Main Question or Discussion Point
If a microwave generator (for e.g., magnetron or klystron used to particle accelerator) is said to have power of for e.g. 3 MW, what does that depend on? Is it related to the electric field amplitude of the electromagnetic wave and how many waves are coming out of the microwave generator and how? Is it related to the frequency of the waves? How can you calculate the megawatt of the device? Thank you.
