X-Ray Production

Front

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

Back

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

Front

How are x-rays produced?

Back

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

Front

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

Back

the inner shell electrons of tungsten atoms.

Front

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

Back

A characteristic x-ray photon

Front

How are characteristic x-ray photons produced?

Back

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

Front

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

Back

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.

Front

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?

Back

66.7 keV.

Front

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

Back

characteristic cascade

Front

The word Bremsstrahlung means?

Back

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

Front

What happens to the filament electron during bremsstrahlung interaction?

Back

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