We studied the electron beam generation in high-current diode with various cathode shapes and the beam propagation through vacuum or plasma delivered to metallic drift tube. The combined effect of external longitudinal and self-consistent azimuthal magnetic fields with the accelerating electric field is discussed. We are interested in obtaining the diode efficiency and beam characteristic in stationary state.

Optically Induced

Due to the high field enhancement factor and photon-absorption efficiency, carbon nanotubes (CNTs) have been widely used in optically induced field-emission as a cathode. Here, we report vertical carbon nanotube arrays (VCNTAs) that performed as high-density electron sources. A combination of high applied electric field and laser illumination made it possible to modulate the emission with laser pulses. When the bias electric field and laser power density increased, the emission process is sensitive to a power law of the laser intensity, which supports the emission mechanism of optically induced field emission followed by over-the-barrier emission. Furthermore, we determine a polarization dependence that exhibits a cosine behavior, which verifies the high possibility of optically induced field emission.
