METHOD FOR EXCITING SCREEN OF ELECTRON-BEAM LASER DEVICE |
摘要 |
FIELD: electronic engineering; data displays, optical raster microscopy, etc. SUBSTANCE: method involves irradiation of screen by electron beam; mentioned beam has circular distribution of current density in screen plane. Proportion between internal and external diameters of distribution circle of electron-beam current density in screen plane may be within following range: <EMI ID=0.456 HE=6 WI=36 TI=CHI>. Moreover, internal diameter of this circle may be between 5 and 70 mcm and external diameter, between 20 and 100 mcm. EFFECT: reduced divergence of device beams. 3 cl
