Indeed, and this is a reason why, traditionally, electrons are studied using linear accelerators, rather than rings. It was the main purpose of Stanford Linear Accelerator (SLAC) as I understand it.
When electrons are accelerated in rings, it's usually because you want to do something with the radiation, and not the electrons.
Ordinary consumer equipment already accelerates electrons enough to produce X-rays. Or at least, it did, back in the CRT era. This accelerator is presumably more powerful than consumer entertainment hardware.
