The mass spectrometer described in Example 26.2 is a simple but largely obsolete design. Modern mass spectrometers generally use a single detector at a fixed location, and they scan the magnetic field strength B by varying the current in an electromagnet. The known value of B at the time a detection is made then allows the charge-to-mass ratio of the detected species to be determined. Furthermore, modern designs don't use the full semicircle as for the mass spectrometer in Example 26.2 but generally take the particles through a smaller circular arc. (Figure 1) shows the magnetic portion of such a mass spectrometer. Ions enter the magnetic field after being accelerated through a potential difference of 2.75 kV. They enter moving perpendicular to the field region, a distance of r = 13 cm from the apex shown, and, if they have the appropriate charge-to- mass ratio, they strike the detector, which is located the same distance from the apex as the entrance slit. What range of magnetic field strengths is needed in this design to detect singly ionized atoms ranging from carbon-12 to iron-56?
