PHYS1008 Study Guide - Final Guide: Vacuum Tube, Compton Scattering, Bremsstrahlung
Document Summary
Bremsstrahlung x-ray is made by energy released by fast moving electron that is changing its direction. X- ray is produced in forms of the emitted energy. Bremsstrahlung produce continuous spectra and this is an example of poly-energetic x-ray. Characteristic x-ray is made by high energy electron bombarding with inner shell electron. High energy electron knocks off the inner shell electron and creates vacancy in the electron shell. Higher shell electron jumps down the shell to fill in the vacancy. As higher shell electron has higher energy, in order to meet the energy conservation law, it releases energy in forms of x- ray. As initial energy of electron is set, energy of x-ray released is restricted therefore, it is an example of mono-energetic x-ray. The energy release is represented as a peak in the spectra. Explain generation of x-rays by a diagnostic equipment, identify basic features of a diagnostic x-ray tube. Transformer amplifies the voltage in order to reduce resistance.
