Chapter 8

what conditions are necessary for the production of X-rays?

• source of electrons

• target

• high voltage

• vacuum

percentage of electrons to xrays

less than 1%

percentage of electrons to heat

99%

2 target interactions to produce xrays

• Brems

• Incident

Brems equation

entering electron - exiting electron

the greater the angle of deflection from the original path ___ energy is lost and ___ energy is given to the photon and __ energy is given to the exiting electron

more, more less

the great the angle of deflection the less energy given to the electron and more energy is given to the photon

The closer the electron travels to the nucleus the __ it will turn

greater

what contributes the most to the primary beam?

Brems

tungsten K shell binding energy

69.5 KeV

what is kilovoltage peak

highest energy photon you can get out of your machine

what is the beam mostly made up of?

brems
