A low pressure ion source for a neutron source comprises a filament cathode and an anode ring. Approximately 150V is applied between the cathode and the anode. Other electrodes, including a heat shield, a reflector and an aperture plate with a focus electrode, are placed at intermediate potentials. Electrons from the filament drawn out by the plasma and eventually removed by the anode are contained in a magnetic field created by a magnet ring. Ions are formed by electron impact with deuterium or tritium and are extracted at the aperture in the focus electrode. The ion source will typically generate a 200 mA beam through a 1.25 cm/sup 2/ aperture for an arc current of 10A. For deuterium gas, the ion beam is over 50 percent D/sup +/ with less than 1% impurity. The current density profile across the aperture will typically be uniform to within 20%.

Photograph used for a story in the Daily Oklahoman newspaper. Caption: "Edgemere Elementary School children in OKC were mesmerized by movie characters C3PO and E.T. as the two, along with Mike Reger, an official at Doctor's General Hospital, were helping to promote the "Hot Dot" safety program. Nickel-sized orange-reflective dots that can be placed on clothing, bicycles and skateboards were promoted, resulting in children being more visible at dusk or in early morning hours."
