Characteristic x-ray emission
WebCharacteristic X-ray generation When a high energy electron ( 1) collides with an inner shell electron ( 2) both are ejected from the tungsten atom leaving a 'hole' in the inner layer. This is filled by an outer shell electron ( 3) with a loss of energy emitted as an X-ray photon ( 4 ). Bremsstrahlung/Braking X-ray generation WebCharacteristic x-rays are produced by A. braking electrons B. excitation of outer shell electrons C. nuclear fragmentation D. released binding energy released binding energy The quantity of bremsstrahlung radiation increases proportionately with increased _____. A. kVp B. mAs C. filtration D. rotor speed mAs

WebEmission Spectrum The measure of x-ray energy of all x-rays, a graphical representation of the relative quantity of photons of each type of energy in the x-ray beam. Factors affecting the x-ray emission spectrum (p130) 1. Tube Current 2. Tube Voltage 3. Added Filtration 4. Target Material 5. Voltage waveform WebCharacteristic X-Rays The most energetic X-ray emission comes when a vacancy in a K shell (n =1) is filled by an outer electron. Removal of a 1s electron from a neutral atom raises it to the highest energy state represented by 1s1s −1 or 1 2 S 1/2 or K I. Removal of a 2s electron (2s2s −1) gives rise to L 1 state (2 2 S 1/2 ).
