As the particle bunch passes through the tube it is unaffected (the
tube acts as a (Click link for more info and facts about Faraday cage)
Faraday cage), while the frequency of the driving signal and the
spacing of the gaps between electrodes is designed so that the maximum
voltage differential appears as the particle crosses the gap. This
accelerates the particle, imparting energy to it in the form of
increased velocity. At speeds near the speed of light the incremental
velocity increase will be small, with the energy appearing as an
increase in the mass of the particles. In portions of the accelerator
where this occurs the tubular electrode lengths will be almost
constant.

Also it looks like the EM fields of accelerator cavity are in every
respect
*the coolest thing in the world*.
If there's a better piece of gear than a particle accelerator...is
there?

You can think of them as the 'wrong' end of a telescope.

Well I tried, but I'm not sure I exactly get it. I'd like to...would
you care to elaborate on this analogy?

WRT a better piece of gear, this was the best I could do -
