- As a followup to Ric's analysis (which I agree with), I'd like
- to add the following. We know that B fields can't accelerate
- electrons. So, to get our stream of 850 MAmps (or whatever it
- was) accelerated to nearly the speed of light would take a
- massive voltage, even if we ignore relativistic effects,
- and a phenomenal amount of power. Ignoring dielectric breakdown
- for any substance that I can think of, we then find that the
- B field necessary to create anything near a helix is also
- absurdly large.

- I would recommend that HDGARNER (sorry if I misspelled this)
- take a look at the construction of a cathode ray tube, and an
- e beam particle accelerator. Those will give numbers that
- are more typical of the kinds of thing that we can do.
