Problem 4 (25 points) The figure below shows a mass spectrometer, a device used to measure the masses of ions. Consider a positive ion of unknown mass m and charge q = 3.2 x 10-19 C. The ion is first accelerated from rest through a potential difference of magnitude 1v1 = 750 V inside a source. After leaving the source, it travels upward at constant speed and enters a region of uniform magnetic field B = 2.5 T directed out...

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...

Two particles, alpha and beta, with the same speed enter a region with a uniform magnetic field is directed either into the page or out of the page and perpendicular to their velocities (in the figures, the magnetic field is zero in the unshaded region and non-zero in the shaded region). The particles have the same magnitude charge but different masses. Particle alpha is negative; particle beta is positive. The particle's trajectories are shown below: Which of the following statements...

A beam of mixed ions is accelerated up to a uniform velocity v. The ions 1 and 3 have exactly the same magnitude of charge, while ion 2 has double that magnitude of charge. These ions are directed into a chamber with a uniform magnetic field B (oriented perpendicular to the page in the figure shown). Rank the mass of these ions, from greatest to least. Uniform magnetic field chamber 3 m1 > m3 > m2 m3 > m1 >...

Part A (Figure 1) shows the semicircular path through which charged particles travel in the magnetic field of a mass If the particles are oxygen ions carrying a charge of -2e and the magnetic field magnitude is 0.24 T, how long does it take each ion to travel the semicircular path through the magnetic field? The mass of an 02 ion is 2.6× 10 26 kg. Express your answer w ith the appropriate units. Figure 1 of 1 B into...

• The figure shows the essentials of a mass spectrometer, which can be used to measure the mass of an ion; an ion of mass m (to be measured) and charge q is produced in source S. The initially stationary ion is accelerated by the electric field due to a potential difference V. The ion leaves S and enters a separator chamber in which a uniform magnetic field is perpendicular to the path of the ion. A wide detector lines...

In mass spectrometry, a sample’s molecules are ionized in a
vacuum and then exposed to a uniform electric field created by a
high-voltage plate in the acceleration chamber. The electric field
accelerates the ions until they arrive at the next section of the
device, designated as the separation chamber. In this section, the
drifting ions are sorted by their mass-to-charge ratio (m/q).
The separation chamber in a time-of-flight mass spectrometer
(TOF-MS) is linear and has no electric or magnetic fields....

A uniform electric field E points toward the top of the page (in red) and exists over a distance d. Above that electric field region is a region of uniform iform magnetic field B, which is pointing into the page. The two fields do not overlap. A positive charge +q with mass m is released from rest at...
Velocity Selector-multiple choice
The Velocity SelectorIn experiments where all the charged particles in a beam are required to have the same velocity (for example, when entering a mass spectrometer), scientists use a velocity selector. A velocity selector has a region of uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the motion of the charged particles. Both the electric and magnetic fields exert a force on the charged particles. If a particle has precisely the right velocity, the...
