As we increase the accelerating voltage, electrons are gaining more and more kinematic energy and they are colliding with atoms elastically until the kinematic energy reaches the first excitation level of the atom. When the first excitation level is reached, inelastic collisions occur and the electron will transfer all the kinematic energy it has to the atom. This corresponds to a dip in current detected by the anode due to the sudden decrease of electrons that reach the anode. As the accelerating voltage keeps increasing, there will be more dips, corresponding to multiple integers of inelastic collisions happened in the tube.
