a. The electrons that are boiled off the filament are attracted to the ___________.
b. The area on the target that the electrons strike is called the_________________.
c. The angle on the anode is usually between ____and ____degrees.
d. The exposure factor, ______, controls the speed of electrons flowing from the cathode to the anode.
e. The anode should be constructed of a material that has a high atomic number and high melting point. Two examples of suitable material are _________and____________.
In a x-ray tube, there are two main structures: the filament and the anode. To generate x-rays, electrons need to interact with a material with high atomic number, as they can thus manipulate the trajectory of flying electrons easier, and also allow for more electron-electron interactions to occur (because in comparison, low atomic number = less attractive force from the nucleus and generally less electrons as well). The higher melting point is required because the ...
