I'm not a particle physicist but a particle accelerator engineer.
GeV energies for electrons are achievable with a reasonably sized synchrotron like Diamond Light Source[0].
The magnets required to keep electrons in line are quite a bit smaller than those required for protons due to the mass difference. Small refrigerator sized verses small car sized.
