Abstract :
The radial divergent sheet beam electron optical system focused by a radial uniform magnetic field is designed in this paper. It is shown that the radial divergent sheet beam with size of 8 deg×0.23 mm, generated by the electron gun with 1700V, 151 mA, can stably pass through the beam drift tunnel with transverse size of 20 deg×0.52 mm and the length of 20 mm in a radial quasi-uniform magnetic field.
