Abstract
The electric circuit, design, and electric and triggering characteristics of the ГИН-1200 small-sized 12-stage high-voltage pulse generator used for charging a double forming line to 1 MV for a 300-ns period are described. The generator is mounted in a metallic housing with the transformer-oil insulation. The storages in stages of the generator are KMK 100–0.017 (100 kV, 0.017 μF) capacitors with a 1-kJ total stored energy. The switches are trigatron gaps filled with a 20% SF6 + 80% N2 gas mixture. The gap housings are assembled into one line. The through-passing axial channel ensures spark illumination of adjacent intervals, thereby improving the triggering characteristics of the generator. The operation-time scatter of the ГИН-1200 generator at an 85-kV charging voltage and 65% electric-strength margin was ≤10 ns, and the operation delay time was ∼100 ns. The ГИН-1200 generator operated ∼2000 times and demonstrated reliable stable operation.
