Particle Accelerator Problems 1. What is the total energy of a proton whose kinetic energy is 15 GeV? What is its wavelength? 2. The voltage across the dees of a cyclotron is 50 kV. How many revolutions do protons make to reach a kinetic energy of 15 MeV? 3. What is the time for one complete revolution for a very high-energy proton (v = c) in the 1km radius Fermilab accelerator? 4. What is the wavelength attainable using 400 GeV protons at Fermilab? 5. Protons are injected into the 1-km radius Fermilab synchrotron with an energy of 8 GeV. If they are accelerated by 2.5 q each revolution, how far do they travel and approximately how long does it take for them to reach 400 GeV? 6. What magnetic field intensity is needed at the 1-km radius Fermilab synchrotron for 400 GeV protons? Use the relativistic mass. 135
