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.
The stationary anode in an x-ray tube is a solid bar of copper with an inset of tungsten on the face of the bar opposite the cathode filament.The tungsten target has a high melting point to withstand the intense heat of the x-ray beamâthe copper conducts the heat away.anode-film distance. see focal-film distance.n x-ray tube in which the anode rotates when x-rays are being produced. This means that there is a larger effective target surface of the anode which can be available to generate x-rays. stationary anode. a non-rotating anode in an x-ray tube so that the target surface is comparatively small.
