The psychology degree is popular: the American Psychological Association states that psychology is the fourth most common major among U.S. students. Aside from academia, research and clinical counseling, a wealth of employment options exist.
rotating anode. focal track made of tungsten -rhenium which spins on the copper anode rotor and has molybdenum backing because these metals conducts it draws the heat away from the anode. - because the anode is rotating the electrons dont hit at the same spot everytime so the anode does not over heat. focal spot.
In a rotating anode tube, the anode target disc rotates on a highly specialized ball bearing system. The target is subjected to a focused stream of electrons emitting from the cathode and accelerated by a high potential difference between the target disc and the cathode.-ray sources use an X-ray generator to produce a flow of electrons. Electrical current is then transformed to a higher voltage. The energy of the X-ray depends on the electric potential difference of the cathode and anode.
