I haven't checked out your image yet, but I have a pretty good idea of
the effect you're striving for and how to do it....

Save the motion paths you've created for your spinning electrons and
apply it to progressively smaller and more transparent versions of the
electron object with the motion paths shifted by one for each object.
Use object dissolve instead of surface transparency to speed up
rendering...and don't activate double-sided polygons for these electron
trails...in fact, use single point polygons if you can, they render even
faster although they may not provide the exact look you want.

Another way of doing this is to parent the electron and the electron trail
objects to a null object and just spin them all using the null object...
much easier way of achieving this affect.

With either of these techniques, you'll still need to turn on a little
motion blur...just enough to smooth things out.


Hope this helps.....
