Description
A magnetically insulated ion diode has been constructed with a spherically focusing geometry. The diode has been operated at voltages of approx.250 and approx.500 kV, with impedances adjusted to 2--3 and 7--10 Ω, respectively. The pulse length was approx.85 ns. Total ion currents were > or =30% of the diode current. In the high-voltage case, a focal current density of 2100 A/cm2 was obtained; this is > or approx. =90 times the anode ion current density. Auxilliary magnetic fields were used to steer the beam, with the beam deflection as calculated for a single proton. The diode design and diagnostic techniques are described, as well as possibilities for improvements suggested by our data
