Abstract
A heater and support structure for a line cathode includes heater electrodes and an S-shaped cathode support member arranged between the heater electrodes. The heater electrodes and the S-shaped support member have a higher resistance than the cathode and thus heat flows into the cathode to compensate for heat radiation losses and the support compensates for thermal expansion to retain the cathode at a substantially constant position.
