Russian electric physicists have built a generator that emits electrical pulses with a peak power of 54 gigawatts. This “energy cannon” is about 6 meters long, half a meter thick.

54 gigawatts of electrical power can be said to correspond roughly to a hundred nuclear reactors. The reactors at the domestic Loviisa power plant generate just over 500 megawatts of electricity each.

    The secret of the tremendous electrical power is, of course, the short duration, which keeps the total energy of the pulse at most moderate or even small. Precisely Sergei Rukinin and the pulse generated by his colleagues lasted 170 picoseconds, or about one-sixth of a second, and had an energy of 6.7 joules.

    researchers call 54 gigawatts of electrical power a new record for electrical pulses of less than one nanosecond. However, power lags far behind, far behind laser techniques that have created pulses that are even petawatt effective, or hundreds of thousands of times more powerful. Used to generate laser pulses cpa technology

    you will see to enhance the original laser pulse with optical mechanisms that are not suitable for generating electrical pulses.

    The maximum voltage of the pulse of the Rukin group was 1.62 megavolts, which would mean that the effective electric current was about 33 kiloampers. The energy source of the equipment is in a “solid state” (engl.solid-state

      • ), ie it does not contain mechanically moving parts. The pulse was magnetically condensed in three stages from a peak of initially seven nanoseconds to about 40 times shorter.

      Extremely short and efficient electrical pulses are utilized in basic research in Electrophysics, among other things, to create the shortest and most efficient electronic beams possible. The scientists ’scientific report is freely readable and also presents a schematic of the structure of the cannon. The record was reported to be published by the magazineIn a press release from the U.S. Institute of Physics (AIP)


      The magnitude of the total energy of the pulse can be estimated by multiplying the power and time values ​​mentioned at the beginning (the result would be nine joules). However, the exact result is not revealed by that head landing because the peak power is higher than the average power. Pulse duration was measured in the standard manner as the length of time during which the power exceeded half of its instantaneous maximum.The story was originally published
