Part A Medical Cyclotrons Need Efficient Sources Of Protons To Inject Into Their Center In One Kind Of Ion Source Hydr 1 (24.54 KiB) Viewed 33 times

Part A Medical cyclotrons need efficient sources of protons to inject into their center. In one kind of ion source, hydrogen atoms (.e., protons with one orbiting electron) are fed into a chamber where there is a strong magnetic field. Electrons in this chamber are trapped in tight orbits, which greatly increases the chance that they will collide with a hydrogen atom and ionize it. One such source uses a magnetic field of 50 mT, and the electrons kinetic energy is 1.8 eV if the electrons travel in a plane perpendicular to the field, what is the radius of their orbits? (me = 9.11x 1031 kg. ge = 1.60 x 10c, 1ev = 1.60 103) Express your answer with the appropriate units. HÅ ? Value Units Submit Best Answer
