Stangenes Industries has developed a solid-state inductor-driven kicker magnet pulse generator for use in a particle accelerator application. The system operates in a neutron environment which precludes the use of standard capacitor-driven systems. A 500–700 A pulse is produced by switching high-current through a large 360 μH inductor from the circuit return into a 6.5 μH kicker magnet. The DC magnetic...
Research and development of a parallel boost network providing droop compensation for long pulse applications has reached a milestone at Stangenes Industries. The demonstration unit is capable of producing a 3.2 kV / 3.2 A pulse that persists for 3.6 ms with a stability of better than 1%. The pulse is generated by two modular stages oriented in a Marx topology with a parallel droop compensator stage...
Continuing investigations indicate that a solid-state Marx modulator utilizing a novel boost circuit topology can generate a 4 ms long megawatt pulse at 10 Hz with a voltage droop of less than 1%. The boost regulator operates by charging the discharge capacitor with energy stored in a boost inductor. Both the discharge and boost capacitors are charged to the same pre-pulse voltage, so a single power...
High-power solid-state modulators have emerged as reliable, tunable, and cost-effective alternatives to current spark gap and thyratron technologies. The persistent improvement of the power, speed, and availability of solid-state components is generating increased commercial interest in their development. Solid state pulsed systems are optimal for technologies demanding stringent and stable pulse...
SPICE simulations indicate that a solid-state Marx modulator utilizing a novel boost circuit topology can generate a 5 ms long megawatt pulse at 10 Hz with a voltage droop of less than 1%. The boost regulator operates by charging the discharge capacitor voltage with energy stored in a boost inductor. Both the discharge and boost capacitors are charged to the same pre-pulse voltage, so a simple power...
The pulsed modulator has evolved from the early spark gap Mark Generators thru many different design forms to the present in which the Marx design returns using Solid State switches. The paper will chronicle the different types of pulsed modulators, including hard tube/switched modulators, pulse forming network modulators, induction/fractional turn modulators and Marx type modulators. The use of the...
