Item 7
J. J. Thomson is best known for his discoveries about the nature of cathode
rays. His other important contribution was the invention, together with one of
his students, of the mass spectrometer, a device that measures the ratio of
mass m to (positive) charge q of an ion.
The spectrometer consists of two regions as shown in the figure. (Figure 1)
In the first region an electric field accelerates the ion and in the second the
ion follows a circular arc in a magnetic field. The radius of curvature of the
arc can be measured and then the m/q ratio can be found.
