A typical Energy Dispersive X-ray SpectrumA series of characteristic peaks on abackground of continuum X-rays, straypeaks and artifacts.
Continuum X-raysContinuum X-rays or (bremsstrahlung) aregenerated when electrons interact withmatter.Result of incident electrons decelerating infield associated with atom.Gives counts in the X-ray spectrumbetween zero and value of incidentelectron beam energy.http://www.youtube.com/watch?v=P0Xi-dJskY8http://www.youtube.com/watch?feature=endscreen&v=n9FkLBaktEY&NR=1Characteristic X-raysIf an incoming high energy electron ejects an electron from the K shell it will bereplaced by an electron from a higher shell.This will create a characteristic X-ray or Auger Electron.If replaced from the L shell it generates a Kα X-ray.If replaced from the M shell it generates a Kβ X-ray.
