Copper k alpha beta
WebAug 22, 2024 · K (alpha) is more intense than k (beta). Copper targets are easier to cool than most other possible electrodes. Most references have standardized on the Cu k (alpa) so it is easier refer to other results. Other wavelengths are acceptable. Why is the wavelength of K-alpha radiation in copper K-alpha constant? This because wavelength … WebPhoton energies, in electron volts, of principal K-, L-, and M-shell emission lines.

The K-alpha indicates that the electron has fallen from the next higher orbital (L-shell) while the K-beta is from 2 orbitals higher (M-shell). All elements when exposed to x-rays or electrons in the range 300 eV to about 60 keV will be fluoresced in the x-ray region.
