X-Ray Production

During x-ray production the electrons penetrate the target how deep?

• Electrons travel approximately 0.5 mm into the target during x-ray production.

• Electrons travel approximately 0.2 mm into the target during x-ray production.

• Electrons travel approximately 5.0 mm into the target during x-ray production.

How are x-rays produced?

• X-rays are produced by both characteristic and bremsstrahlung interactions between the filament electron and the tungsten atom.

• X-rays are produced by both photoelectric and Compton interactions between the filament electron and the tungsten atom.

• X-rays are produced by both coherent scattering and photodisintegration interactions between the filament electron and the tungsten atom.

When filament electrons enter the anode target, they interact with what?

• When filament electrons enter the anode target, they interact with the inner shell electrons of tungsten atoms.

• When filament electrons enter the anode target, they interact with the outer shell electrons of tungsten atoms.

• None of the above

When a filament electron knocks out a K shell electron from the tungsten atom, it leads to what?

• A characteristic x-ray photon

• A brems x-ray photon

• None of the above.

How are characteristic x-ray photons produced?

• To produce characteristic radiation, outer-shell electrons must drop into an inner-shell vacancy created by the filament electron knocking out the orbital electron.

• To produce characteristic radiation, inner shell electrons must drop into an outer shell vacancy created by the filament electron knocking out the orbital electron.

• None of the above

The energy of the characteristic x-ray photon depends on what?

• Characteristic radiation depends on the energy level of the incoming electron, the binding energy of the electron that is knocked out and the shell of the orbital electron that drops into the vacancy.

• Characteristic radiation depends on the energy level of the outgoing electron, the binding energy of the electron that is knocked out and the shell of the orbital electron that drops into the vacancy.

• None of the above.

A filament electron removes a K shell electron and an M shell electron fills the vacancy. The K shell binding energy is 69.5 keV and the M shell binding energy is 2.8 keV. What is the energy of the K-characteristic photon produced?

• 66.7 keV.

• 69.5 keV.

• 56.7 keV.

The process of a series of outer-shell electrons filling inner-shell vacancies right after the other is called?

• characteristic cascade

• characteristic x-rays

• characteristic sequence

The word Bremsstrahlung means?

• Bremsstrahlung is the German word for “braking” or “slowing down” radiation.

• Bremsstrahlung is the German word for “speeding up” radiation.

• None of the above

What happens to the filament electron during bremsstrahlung interaction?

• During the bremsstrahlung interaction, the filament electron is attracted to the nucleus, causing it to slow down and change direction.

• During the bremsstrahlung interaction, the filament electron is attracted to the orbital electron, causing it to slow down and change direction.

• None of the above.
