Title:
【発明の名称】性能を強化した電界効果カソード
Document Type and Number:
Japanese Patent JP2002536808
Kind Code:
A
Abstract:
A microwave modulable field-effect cathode which includes at least one array of emissive tips. A microwave modulation signal is produced by a device including a microwave-controllable semiconductor modulation element which is close to the tip array, and a short microline for conveying the modulation signal to the tip array. The microline provides impedance matching between the tip array and the semiconductor modulation element. Such a device can find application as a compact field-effect cathode, as one example.
