The Tevatron accelerator at Fermilab (Illinois) is designed
to carry an 11-mA beam of protons (q = 1.6 × 10-19 C)
traveling at very nearly the speed of light (3.0 × 10$ m/s)
around a ring 6300 m in circumference. How many protons
are in the beam?
You are working as a medical assistant at a proton beam facility, where high-speed protons are used to bombard cancer cells. The protons are accelerated with a cyclotron, which you find very interesting because of your background in physics. You are explaining this to a patient who has some familiarity with cyclotrons. She asks, “How many revolutions does a proton make in the cyclotron before it reaches its exit kinetic energy?” You are taken aback, both by the high quality of her question and the fact that you never thought of such a question before. You tell her you will try to get her an answer before she finishes her treatment today. When you are finished preparing her for treatment, you go into the cyclotron room and look at the machine. Only three numbers are available on the machine labeling: the exit energy K = 250 MeV, the radius at which the protons exit, r = 0.850 m, and the accelerating potential difference between the dees, ΔV = 800 V. You go back to the patient prepared…

- The proton-proton chain is the multi-step process that powers the Sun via fusion of hydrogen into helium. In the first step of the proton-proton chain, a positron is produced when two protons fuse together (with one proton converting to a neutron). The emitted positron quickly collides with its anti-particle, the electron. (Recall that the electron and positron have exactly the same mass, but opposite electric charges.) The electron and positron then completely annihilate, converting all of their rest mass into two gamma-ray photons. Given a single particle of mass m, the amount of energy E produced when all of its mass is converted to energy is given by Einstein's famous formula, E = m c?, where c = 2.9979 x 10° m/s is %3D the speed of light. We also learned that the energy Ephoton of a single photon is related to its frequency f or wavelength A via Ephoton = hf = hc where h = 6.626 x 1034 m² kg/s is a fundamental constant of nature called Planck's constant.
