2020-08-24: Can Future Colliders Break the Standard Model?

  • 01:22: ... first was the linear accelerator, or linac, which uses oscillating electric fields to accelerate charged particles in a straight line, while the beam is ...
  • 01:32: ... cyclotron quickly followed - here the particles are still accelerated by electric fields, but now a constant magnetic field causes the beam to spiral outwards ...
