Neither. It's not part of the electric field (which is radio frequency per article, and invisible), and it's not there to make it science-y. It's there (perhaps at both ends) to illuminate the trap space and the trapped particles, to make them visible. The particles are almost microscopic. That's
118:
I think it's somewhat important to ask: Is the green light functional in some way? Because the ion trap works with rapidly changing electrical fields. If the light's part of the device, then of course I'd support. If it's just being used to make it look "science-y", though, I can't.
194:. There appears to be pretty significant subject motion blur on the trapped grains, but I think that serves an encyclopedic purpose, to show their motion within the trap rather than conveying the impression that it freezes everything in place. —
72:. Science subjects are hard to depict. This brings attention to the subject, and as FPC instructions say: "to the point where users will want to read its accompanying article" (I hope). Not a high pixel count but meets the FP requirement.

what the device is designed for, ionized/charged particles, i.e. very small. It will be hard to see much there with room lighting, camera flash and such.

Yes the motion is part of its physics, and not an anomaly.
