Question

Why a laboratory might want both Cu and Mo data-collection capabilities?​

Answer 1

$answer$

Answer:

Copper K-α is an x-ray energy frequently used on labscale x-ray instruments. The energy is 8.04 keV, which corresponds to an x-ray wavelength of 1.5406 Å. When an electron vacancy in the K shell is filled by an electron from the L shell, the characteristic energy/wavelength of the emitted photon is called the K-alpha (Kα) spectral line, and when the K shell vacancy is filled by an electron from the M shell, the characteristic energy/wavelength of the emitted photon is called the K-beta spectral line. K-alpha radiation has higher intensity rather than K-beta, so it is commonly used in diffractometers
