			If we batch the ionized plasma, we can have a pulsed group of ions.

			We can string that out with an accelerating voltage, so that at the end of the acceleration phase all the light ions are at the front of the beam and all the sluggish heavyweights are at the back. Okay so far? A long chain arriving at the deflection plate gap, in time order of isotopes.

			What we now do is to deflect them. The trouble is that a constant voltage across the plates will exactly undo the sorting we've achieved. The light ones, because they get there first, are going faster so they deflect less. The heavy ones are going slow so they're being pushed sideways for longer and they end up taking exactly the same path as the light ones did. The beam all ends up in one place.

			But. Here's the cheaty bit. We vary the voltage on the deflector plates with a sawtooth waveform. We hit the light ones at the front with a big kick, the heavy ones at the back with a light kick, and we force the light ones to bend a lot and the heavy ones to bend less.

			If we shape the waveform correctly, the isotope separation by mass number will be linear. Okay, so it's not exactly a sawtooth but it's quite like. The sawtooth repeats just as the next strung-out batch of ions arrives from the next bang event at the plasma gun.
