What is the most efficient way to produce charged particles?

    hello!

    what is the most efficient way to produce charged particles?
    like protons (H+) or electrons or ions or anything like that

    thanks!

    Do you want to really make new particles? Then electromagnetic showers should be the most efficient way - high-energetic electrons that hit a target. If you don't catch them, the newly created positrons will quickly annihilate with electrons again and you did not gain anything.
    But where is the point? If you just want charged particles somewhere, it is sufficient to use existing ones, e. g. release electrons from a solid. This can be done by heating a wire.

    no, I don't want to create new particles (can we create matter? not sure)
    I just want to "produce" charged particles, yes, if heating a wire will give me electrons, that's what I need
    but are you sure by heating a wire I can get electrons? how exactly?

    Yes we can, but only in tiny amounts.

    Thermionic emission -. nearly every old screen (CRT) used that before flat screens became popular.

    Lasers don't produce particles. They produce coherent light.

    The original question has been answered, so this thread is closed.

    I've removed a long digression.
