Abstract

A directly heated line source emitter with beam power (>50 KW/cm ²) is developed. The emitter assembly design parameters and beam characteristics are analyzed using a highly uniform magnetically confined region. Circular cross-sectional tungsten cathodes of diameters 0.9 mm and 1.5 mm were used, and their results are compared. The developed emitter configuration ensures low angular divergence, millisecond evaporation time for large samples, operational reproducibility, and beam stability. The emitter source has been tested by experimentally developing extremely homogeneous magnetic field in large cylindrical region of more than one-half of the coil's diameter.
