  • EMP pulse

    From RichD@21:1/5 to All on Mon Jun 13 13:57:02 2022
    Have you heard of electromagnetic pulse? Supposedly,
    a big nuke exploded over Colorado will erase every magnetic
    memory west of the Mississippi. (not sure about semiconductor memories)

    Can anybody here explain the physics of this claim?

    Nukes can make giant EMP pulses. One high atmospheric test crashed
    Hawaii.

    There are also non-nuke EMP weapons, like jet planes tiled with pulse
    emitters, or rockets with explosive-powered EMP generators.

    google HPM weapons

    Might be a defense against cheap drones.

    The physics behind the "explosively-pumped flux compression generator"
    is pretty simple conceptually, you have a solenoid wrapped in high
    explosive. Dump a capacitor bank into it to get a large current moving,
    then detonate the explosives and symmetrically crush it, inwards towards
    the longitudinal axis of the solenoid.

    Lenz's law does the rest.

    The planes have tiles that are antennas, basically a charged capacitor
    with some shorting device, possibly a poly-diamond film.


    Seems more amenable to a longer duration effect than the former. Quieter
    too, I bet the EPFCG makes an awful racket, to put it mildly

    The discharge tiles make one giant spike at low rep rate. Presumably
    one terawatt impulse can blow out sensors or trash the CPU in an
    incoming threat. Of course, the launching airplane has to survive it
    too.
