Abstract
A planar filament comprising two bonding pads and a non-linear filament connected between the two bonding pads. The planar filament may be wider in the center to increase filament life. The planar filament can form a double spiral-serpentine shape. The planar filament may be mounted on a substrate for easier handling and placement. Voltage can be used to create an electrical current through the filament, and can result in the emission of electrons from the filament. The planar filament can be utilized in an x-ray tube.
