Abstract

PURPOSE: To obtain uniform electron beam and high picture quality irrespectively of deflection width, by providing two pairs of polarization electordes while bringing the polarization voltage at the side near to the electron beam lead-out electrode higher than the polarization voltage at other side thereby maintaining the symmetry of electron beam.
CONSTITUTION: Two pairs of polarization electrodes (4a, 4b), (5a, 5b) are provided on polarization electrode substrate 3 while holding linear thermal electron emitter having thermal cathode 1 between them. Polarization voltage higher than that for other side polarization electrodes 4a, 4b is applied on polarization electrodes 5a, 5b at the side near to lead-out electrode 6 of electron beam 7. With such structure thin and sharp electron beam stripe 7 can be polarized considerably with uniform current density and scanned across predetermined width.
