Abstract

The assembly (Fig. 3) has a trio of inline cathodes (21), a first grid (G1, 23) positioned adjacent the cathodes and a second grid (G2, 25) positioned between the first grid and a first focussing electrode (G3, 27). Each grid and electrode has a trio of inline apertures aligned with the cathodes. A common, assymmetric focussing lens is, in use, established between the first focussing electrode (G3) and a second focussing electrode (G4, 29). The lens has a maximum transverse dimension in a first direction parallel to the plane of the inline apertures greater than its maximum transverse dimension in a second orthogonal direction. In order that the cross-section of each electron beam has a greater dimension in the first direction than in the second direction at the beam- entrance of the lens, there is a slotted structure (Fig. 7, 68) associated with said first (23) grid interposing a rectangular slot (68) between each aperture (64) of the first grid and the aligned aperture of the second grid. The long dimension of the rectangle is in the second direction in the first grid (23). <IMAGE>
