Abstract (en)
[origin: EP0696045A1] The cathode (1) includes an insulating substrate (10) and a resistive layer (11) which supports an array of micro-tips (2). Cathode conductors (13) are placed on top of the resistive layer over a thin conductor coat (19). The conductors are organised in columns (15) each column encompassing a large number of micro-tips. The micro-tips are located in the centre of circular openings (17) present along the cathode conductors. Each micro-tip is thus separated from the conductor by a circular area of same resistivity. A control grid (3) is associated with the cathode and separated from the conductors by two insulating layers (16,18).
