Abstract
An ionization device includes a first electrode comprising a conductive member coated with a dielectric layer. The ionization device also includes a spine extending adjacent to and at least partially along the first electrode. The ionization device further includes a second electrode comprising conductive segments disposed adjacent the first electrode. Each one of the conductive segments contacts the spine at a respective contact location. The dielectric layer of the first electrode separates the conductive member of the first electrode from the spine and the second electrode. The ionization device is configured to create plasma generating locations corresponding to respective crossings of the first electrode and the second electrode.
