anode

 [an´ōd]
the electrode at which oxidation occurs and to which anions are attracted. adj., adj ano´dal.

an·ode

(an'ōd),
1. The positive pole of a galvanic battery or the electrode connected with it; an electrode toward which negatively charged ions (anions) migrate (for example, in electrophoresis); a positively charged electrode. Compare: cathode.
2. The portion, usually made of tungsten, of an x-ray tube from which x-rays are released by bombardment by cathode rays (electrons).
Synonym(s): positive electrode

anode (an´ōd),

n the electrically positive terminal of a roentgen ray (radiographic) tube; a tungsten block embedded in a copper stem and set at an angle of 20° or 45° to the cathode. The anode emits roentgen rays (radiographs) from the point of impact of the electronic stream from the cathode.
anode, rotating,
n an anode that rotates during radiograph production to present a constantly different focal spot to the electron stream and to permit use of small focal spots or higher tube voltages without overheating the tube.

anode

the positive electrode or pole to which negative ions are attracted.
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 beam—the copper conducts the heat away.

anode-film distance
see focal-film distance.
rotating anode
an 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.
