The energy of the n-th Landau level equals h-bar times this quantity times n plus one-half. For 10 points each:
[10h] Name this quantity that is classically equal to q times B over m. This quantity determines the rate of circular motion of a charged particle in a uniform magnetic field.
ANSWER: cyclotron frequency [prompt on frequency; prompt on angular frequency or omega]
[10e] Cyclotrons are a cylindrical type of these devices that have largely been supplanted by circular synchrotrons. One such synchrotron is CERN’s Large Hadron Collider.
ANSWER: particle accelerators [accept beam colliders or atom smashers]
[10m] Lighter particles in synchrotrons produce large amounts of radiation because the power of synchrotron radiation depends on this quantity to the fourth. This quantity equals one over the square root of the quantity “one minus v-squared over c-squared.”
ANSWER: Lorentz factor [or Lorentz gamma; prompt on gamma]
