Repetitive pulsed-power generator “ETIGO-IV”

A new repetitive pulsed-power generator “ETIGO-IV” has been developed for the applications in materials science, pulsed ion-beam acceleration, and high-power microwave generation. It is capable of delivering, to a matched load, an output pulse of 400 kV in peak voltage, 13 kA in peak current, and 120 ns in pulsed length, at the repetition rate of 1 Hz. “ETIGO-IV” consists of a high-voltage supply unit, a pulse-forming unit, and a central control unit. In the high-voltage supply unit, the electrical energy of 1.35 kJ stored in the capacitors is delivered, by thyratron switching, to the pulse-forming unit through high-voltage coaxial cables. In the pulse-forming unit, the pulsed high voltage is multiplied by the pulsed transformers and compressed by the combination of a coaxial pulse-forming line and magnetic switches. “ETIGO-IV” is expected to be used for the generation of repetitive, pulsed ion-beam which has potential applications in material processing, such as pulsed ion-beam ablation and pulsed ion-beam surface treatment.
