Abstract
Disclosed are methods and devices suitable for generating electron beams and pulses of radiation. Specifically, in some disclosed embodiments, multiple emitting electrodes of a ferroelectric emitter are sequentially activated, generating a relatively long electron beam pulse that is substantially a series of substantially consecutive short electron beam pulses generated by the sequentially-activated individual emitting electrodes.
Claims23
A ferroelectric emitter, comprising:
- at least two mutually-separated distal emitting electrodes.
5-9. (canceled)
13-19. (canceled)
21-22. (canceled)
A method for generating an electron beam, comprising:
- a) providing a ferroelectric emitter having at least two mutually-separated distal emitting electrodes inside a vacuum;
- and
- b) sequentially activating said distal emitting electrodes thereby generating an electron beam pulse from the emitter that is a series of substantially consecutive short electron beam pulses generated by said sequentially-activated individual distal emitting electrodes.
The method of 23, wherein said generating a beam of electrons from a said emitting electrode comprises:
- generating a plasma with a said emitting electrode;
- extracting electrons from said plasma;
- and
- forming an electron beam from said extracted electrons.
