Ion beam generation on Reiden-SHVS induction adder accelerator

Summary form only given, as follows. Light ion beams to drive inertial confinement fusion can be produced by an inductive voltage adder system. The authors discuss a prototype machine, Reiden-SHVS (super-high-voltage system), which consists of eight-stage induction cavities (4 MV, 40 kA, 100 ns) powered by an 80-kJ Marx generator and a 1.25- Omega pulse-forming line. The output voltage of each group of four cavities is boosted by two inner conductors that feed a negative and a positive high-voltage power pulse to the central diode section. Experiments were performed with a beam-extraction-type ion diode and C/sup +/-C/sup 4+/, N/sup +/, O/sup +/, and Cu/sup +/-Cu/sup 3+/ ions were generated. The typical maximum parameters of this ion diode were a voltage of 3.2 MV, current of 39 kA, ion current of 3.2 kA, and ion current density of 42 A/cm/sup 2/ at 7 cm from the cathode.<>
