The Magnetron is one of the efficiency high-power microwave source, although the energy conversion efficiency decreases with pulsed-power relativistic electron beam. We study the capability to increase energy conversion efficiency of Relativistic Magnetron by using Transparent Cathode. The Transparent-Cathode consists of independent cathode strips. Each cathode strip caused azimuthal magnetic f...

Pulsed power application has emerged to become an important technology in today’s industry beyond defense sectors, although historically the applications included particle acceleration, imploding plasmas and related. Pulsed power refers to the technology where a steady accumulation of energy followed by its rapid release, results in the delivery of a large amount of instantaneous power over a v...

<span lang="EN-GB">DC grids can effectively feed pulsed power loads (PPLs), integrating local energy storage to minimize the impact on other connected and implementing buffered sub-grids isolate susceptible even more. The identification of regulatory limits for PPL integration DC grid response assessment necessitate suitable Power Quality (PQ) metrics. Existing indexes (e.g. ripple distor...

Explosive pulsed power consists of those devices that convert the chemical energy in explosives into electrical energy. In 2004, a series of programs were initiated to develop several types of very compact explosive pulsed power generators. Based on these recent efforts, we now have a better understanding of the weaknesses and strengths of these small generators. As a result, we can now build r...

Here we report a compact monolithic 2000nm pulsed laser with a single spatial mode output, ~1.5ns pulse duration, 8kW peak power and >200mW average power at 20 kHz repetition rate. The gain-switched laser, consisting of a pair of fiber Bragg gratings and 0.5m of thulium-doped single cladding fiber, was core pumped by a high peak power pulsed 1.5 m laser. When the input pulse energy of the 20 kH...

A pulsed power supply with a compact and low-cost electric-double-layer-capacitor (EDLC) is developed for generating magnetic fields long pulse duration of few seconds. The system demonstrated in three experimental setups using 10.7 F- or 50 F-EDLC capacitor bank. By the bank 27 mm wide-bore magnet, field peak strength 24.3 T ∼1 s generated. profiles are reproduced theoretical calculations taki...

Electrically pumped vertical cavity surface emitting lasers (VCSELs) can produce hundreds of mW's of 976 nm CW output in a TEM00 mode when operated with an external cavity configuration. During pulsed operation (<50ns) a significant increase in the peak power is observed, compared to CW operation. High peak powers makes these lasers very well suited for intra-cavity frequency doubling with a no...
