Following a thread on building a cloud chamber I searched some other sites and encountered some eg. diagrams of electron tracks which puzzled me.
I searched for actual photos and found some very irregular tracks ascribed to electrons, but nothing like these. I can't see how they could arise without a very strangely (unreasonably) varying magnetic field.
Sources: Fermilab/SLAC's Symmetry magazine, not copied because may be copyright, but copied from some weird site which had probably copied it from them.
Inevitably they are also copied to instructables.
This latter photo is also copied in a publication by U.o.Birmingham, UK where they are explained as, "The unusual pattern is as a result of being bounced around by heavier air molecules."
That might explain some of the photos I've seen, but they are nothing like these.
Can anyone explain how these tracks occur?
