Synthesis of compressed sheet field-emission flows for terahertz TWT

摘要

The report presents synthesis method of modeling the electron-focusing systems that formed compressed sheet electron beam with supporting the beam magnetic field and field-emission cathode. Results of calculating by synthesis and analysis method of the electron gun with linear compression of the beam 10, micro-perveance of Pμ = 0.035 and 100 mA current are performed. The electron gun forms a sheet beam with a 0.125mm thickness, and 0.7 mm width.
