Synthesis of Electron-Optical Systems with Compression of Sheet Beam for Terahertz TWTs

Electron-optical systems are synthesized to form a converging sheet electron beam with a compression of 15 and 20, a cross section of 0.05 × 2 mm, and a current density of 100 A/cm 2 in the presence of complete magnetic shielding of field-emission cathode. Deformation of low-perveance flux in the pr...

Beschreibung
Zusammenfassung:	Electron-optical systems are synthesized to form a converging sheet electron beam with a compression of 15 and 20, a cross section of 0.05 × 2 mm, and a current density of 100 A/cm 2 in the presence of complete magnetic shielding of field-emission cathode. Deformation of low-perveance flux in the presence of magnetic field in the drift tunnel of slow-wave structure is analyzed with the aid of 3D computer simulation of the electron-optical system with the sheet electron beam.
