The most commonly used ion source is liquid metal ion source (LMIS), typically gallium ... including sputtering, ion implantation, and secondary electron emission. By controlling the ion beam ...

On the face of things, not much, but after seeing [Zachary Tong]’s latest video on liquid metal ion thrusters, we see that they seem to have a lot more in common than we’d initially thought.

The most common of these, field emission electric propulsion (FEEP), utilize liquid metals as its ion source to produce positively charged ions and/or droplets and have previously been studied here at ...
