Abstract
A depressed beam collector and an RF source comprising a depressed beam collector. The RF source may include, e.g., a multi-beam klystron, a single beam klystron, or other RF sources having an electron gun. The beam collector collects spent electrons from the electron gun and comprises a grounded portion configured to collect a portion of electrons entering the collector and a biased portion configured to collect another portion of the electrons entering the collector and having a depressed energy.
Claims20
A depressed beam collector comprising:
- a grounded portion configured to collect a portion of electrons entering the collector;
- a biased portion configured to collect another portion of the electrons entering the collector and having a depressed energy, wherein the grounded portion and the biased portion each form a portion of a wall of the depressed beam collector;
- a high voltage gap comprising a spacing in the wall between the grounded portion and the biased portion;
- and
- a magnetic lens at least partially surrounding the high voltage gap.
