Mass spectrometer

A mass spectrometer, outlined below, is an instrument for separating different ions. Chlorine ions with a well defined velocity will enter through a slot into a region of uniform magnetic field B. where they follow a semicircular path until they reach the upper sensing slot located above the entry slot. The distance between the entry slot and the exit slot is d = 1.30 m.

1. Doro ions have a mass of 35 amu (1 amu equal to 1.66x10-27 kg), carrying a charge of + 1e, when they enter the spectrometer. If the magnitude of the magnetic field B is 0.464 T. What must be the initial velocity of the incoming ions to exit the sensing slot?

Answer:

1. What must be the kinetic energy of the incoming ions for them to exit the sensing slot?

Answer:

1. If we change to chlorine ions with mass 37 amu, but with the same speed, how far from the detection slot will they go?
