Medical cyclotrons need efficient sources of protons to inject into their center. in one kind of ion source, hydrogen atoms (i. 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 90 mt, and the electrons' kinetic energy is 1.6 ev. if the electrons travel in a plane perpendicular to the field, what is the radius of their orbits?
