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.
Claims29
A ferroelectric emitter, comprising:
- an emitter body having a distal face and a proximal face;
- a proximal electrode in contact with at least a portion of the proximal face;
- at least one first distal electrode, located at the distal face of the emitter body;
- at least one first trigger;
- wherein the first trigger is configured to activate the first distal electrode by applying potential pulses to the first distal electrode to cause a first plurality of electrons to be released from the first distal electrode to produce at least one first beam pulse;
- at least one second distal electrode, located at the distal face of the emitter body;
- at least one second trigger;
- wherein the second trigger is configured to activate the second distal electrode independently from the activation of the first distal electrode by applying potential pulses to the second distal electrode to cause a second plurality of electrons to be released from the second distal electrode to produce at least one second beam pulse;
- wherein the ferroelectric emitter is configured to produce an electron beam, consisting of the first beam pulse and the second beam pulse.
