A certain commercial mass spectrometer is used to separate uranium ions of mass 3.92 × 10-25 kg and charge 3.20 × 10-19 C from related species. The ions are accelerated through a potential difference of 109 kV and then pass into a uniform magnetic field, where they are bent in a path of radius 1.13 m. After traveling through 180° and passing through a slit of width 1.19 mm and height 0.879 cm, they are collected in a cup. (a) What is the magnitude of the (perpendicular) magnetic field in the separator? If the machine is used to separate out 0.756 mg of material per hour, calculate (b) the current of the desired ions in the machine and (c) the thermal energy produced in the cup in 1.44 h.

A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from the velocity selector at a speed of 2.92 ✕ 105 m/s and enter a uniform magnetic field of 0.605 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by singly charged ions of 235U and 238U? cm

A mass spectrometer is used to separate isotopes. If the beam emerges with a speed of 253 km/s and the magnetic field in the mass selector is 4.0 T, what is the distance in mm between where the following ions are detected? Remember that the ions trace a semicircular path before being detected. Note: the superscript number in the following says how many nucleons (protons and neutrons) are contained in the ion. The mass of a nucleon is 1.66 10-27...

An accelerating voltage of 7.00 kV is used to accelerate ions into the mass analyzer tube of a magnetic sector mass spectrometer, which has a radius of curvature of 9.49 cm. If ions of m/z 531.8 reach the detector, what is the strength of the magnetic field that is applied perpendicular to the length of the mass analyzer tube?

A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18, the mass of oxygen-16 is 2.66 ? 10?26 kg, and they are singly charged and travel at 2.60 ? 106 m/s in a 1.70 T...

singly charged uranium-238 ions are accelerated through a potential difference of 2.00KV and wnter a uniform magnetic field of magnitude 1.20 T directed perpendicular to their velocities. Significance of this problem: 99% of all uranium that comes out of the ground (uranium mine) is U238. But it is U235 that is used for nuclear power plants (3~6% U235) and nuclear weapons (~90% U235). So the concentration of U235 must be increased (enriched). The concentration of U235 is what must be...

A mass spectrometer is a device for separating particles of different masses from a mixture. For example, the technology is used to investigate qualitative and quantitative changes within thousands of biologically active components such as proteins, lipids and metabolites. A mass spectrometer consists of three sections: The accelerator The velocity selector The magnetic chamber (1) Accelerator (acc): In the accelerator, there is only an uniform Electric field due to a potential difference Vacc across two vertical plates separated from a...
