onto the target, which is loaded with d or t by the impinging ion
beam. Neutrons are emitted at all angles from the spherical genera-
tor (Leung 2006).

A new commercially available NG that also uses a simple diode to gener-
ate neutrons is the radio frequency induction (RFI) plasma NG. In this case,
the deuterium ions are generated in RFI plasma and accelerated across a DC
potential toward a Ti target. e main components are located along a single
axis and tubes with this design are referred to as axial generators. Like the
Penning diode, the RFI plasma NG is fundamentally a diode, but with a RFI
plasma ion source instead of a Penning ion source. Also, like the Penning diode,
the RFI source uses a titanium ta ...
