Sharp Cut off in bremsstralungh

  1. Nov 6, 2009 #1
    Hi with respect to the bremsstralung and the Xray emission, i have a graph of the xray emmision and at the end of the bremsstrahlung, at roughly 35 KeV,there is a sharp cut off.

    Is the reason for this because that 35KeV is the maximum energy of the incident
    electrons, and hence no photon can be emitted with larger energy than
    this, as it is only possible to produce a photon of this energy if the
    electron is completely brought to a stop as it passes through the

    Correct.Some electrons lose all of their kinetic energy on a single impact.If you use a different accelerating voltage the cut off will change accordingly.:smile:
