Ask HN: How can I confuse an ion stream weapon?

If there was an electrical stream via ions by say a tesla weapon that doesnt exist yet. I am wondering how I can confuse it enough (reverse the polarity) or shield. The best I can come up with is hanging grounded wires, magnets or small running electrical on the ceiling. I know of faraday cages. tl;dr: i need to alter polarity of ions in my room, as they come in at electrical faster than light speed, enough to block an ion stream (phaser weapon)
