anode /an·ode/ (an´ōd) the electrode at which oxidation occurs and to which anions are attracted.ano´dal Anode The positive electrode to which an electromagnetic current flows. Mentioned in: Bone Growth Stimulation anode, the electrode at which oxidation occurs. anodal, adj. 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.

A point-to-point effect is created on a microscopic level, and electrons flow from the cathodic roller through the hole or anomaly in the thin film material to the anodic tip of the corona beam gun without increasing the applied voltage. Chelmsford, MA, USA) determined BPb in duplicate analysis by anodic stripping voltammetry. In general, the farther apart the two metals are on the scale, the more likely the anodic metal will be damaged. |
