Ion emitter system
An ion generator includes a high voltage source, a body defining a central axis, and multiple arms extending from the body. The body has a primary conductive line electrically coupled to the high voltage source, and a first insulating covering surrounding the primary conductive line. Each arm has an emitter array and a secondary conductive line. The emitter array is disposed at a distal end of the arm relative to the body. The secondary conductive line is electrically coupled to the primary conductive line at a proximal end of the arm relative to the body and extends to the emitter array. The arms are distributed about the central axis, such that the orientations of the emitter arrays and the connection of each arm to the central body are distributed helically, spirally, or symmetrically with respect to other arms, relative to the central axis.
