A mass spectrometer, sketched below, is a device used to separate different ions. Such ions with a well-defined velocity vo enter through a slit into a region of uniform magnetic field B, where they follow a semicircular path until they strike the detector slit above the entry slit. The distance between the entry and the detector slits is d = 1.90 m.
a.) Chlorine ions of mass 35 amu (1 amu equals 1.66x10-27 kg), carrying a charge of +1e, enter the spectrometer with initial speed of vo = 1.70E5 meters/sec. What value of B is required for these ions to hit the detector?
b.) Equally charged chlorine ions of mass 37 amu now enter the spectrometer. How close to the detector slit will they impact?

A certain commercial mass spectrometer is used to separate uranium ions of mass 3.92 x 10-25 kg and charge 3.20 x 10-19 C from related species. The ions are accelerated through a potential difference of 150 kV and then pass into a uniform magnetic field, where they are bent in a path of radius 0.895 m. After traveling through 180° and passing through a slit of width 1.13 mm and height 0.906 cm, they are collected in a cup. (a)...

In a mass spectrometer chlorine ions of mass 35u and charge +5e are emitted from a source and accelerated through a potential difference of 250 kV. They then enter a region with a magnetic field which is perpendicular to their original direction of motion. The chlorine ions exit the spectrometer after being bent along a path with radius of curvature 3.5 m. What is the value of the magnetic field? (u = 1.66 ´ 10–27 kg, e = 1.6 ´...

The figure below shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio e/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector....

1. A mass spectrometer is a device for measuring the mass of charged ions that are first accelerated by an electric field, and then travel in circular orbits in a uniform magnetic field. Let's assume the chamber at the lower left contains hydrogen gas, but may have some contaminants. The gas is ionized in positively charged atomic ions that are accelerated through a voltage drop V. The ions then enter a region with...
