This is a pretty standard first or second year physics undergraduate experiment, where the charge-to-mass ratio of an electron can be measured. See, for example:

It's actually quite elegant, and was quite similar to the work that J.J. Thomson did to show that cathode rays were in fact charged particles.

Reminds me of the book "Eunoia" by Christian Bok. Each chapter is written using only one of the vowels. Reads like beat poetry.
