Abstract

We have performed studies of free-electron lasers using a superhigh voltage source (SHVS), The SHVS consisted of a pulse forming line (PFL), a distribution line (DL), power feed cables, inductive voltage adders (IVAs), and inductive acceleration cavities (IACs). The power was fed from an intermediate energy storage unit of a Reiden IV pulsed power machine. The characteristic impedance of the PFL and the DL was 1.25 Ω. The DL has forty outlet connectors for power feed cables of 50-Ω Impedance. Each stage of the IVA has four cable connector ports. The applied voltage for a stage was 500 keV. Annealed metaglass was used for the induction core. The final scheme of the SHVS has an eight-stage IVA and a twenty- four-stage IAC. The final output will be 16 MeV and 8 kA with a pulse length of 80 ns. Figure 1 shows the SHVS system.
