Description
Sergey Korotkov and co-authors published a 2026 engineering article on a compact device that fires very short, powerful electric pulses. Such pulse generators serve many areas of experimental physics. Their design stacks four stages in the classic Marx arrangement, where capacitors charge in parallel and discharge in series for a multiplied voltage. The switches here are special devices triggered by a shock wave of ionization.
The first switch fires when a fast-rising overvoltage hits it. That wave then triggers the rest through small capacitors. The whole main unit fits in a palm-sized volume. It can switch pulses reaching twelve thousand volts in eight billionths of a second. Current pulses peak at three thousand amps with a very fast rise. The authors note the design leaves room to push both voltage and current higher. Compact, strong pulse sources matter for labs that cannot house bulky gear.
