The small craters in the target of the anode of an x-ray tube are known as what?

Pitting of the anode's focal track is caused by vaporizing of the tungsten disk, a result of the enormous heat produced during normal operation. Pitting reduces the efficiency of the tube.

How are craters fomed on the moon?
Craters on the Moon are formed by the impacts of meteoroids of varying sizes. Small rocks make small craters, and bigger rocks make larger craters.
These things are known to have battered the moon?
Space rocks. On Earth we would call them "meteors", because they would generally burn up while passing through the atmosphere. The Moon has no atmosphere, so there's nothing to prevent small space rocks from crashing into it. This has left the Moon covered with millions of craters; big craters, little craters, craters IN craters, and craters ON craters.
What is focusing cup?
Filament Cup : A small target for electron bombardment on the anode is essential. (image geometrical un-sharpness). Unless steps are taken, the random thermally induced velocities and mutual repulsion of the electrons leaving the cathode will cause a broad beam to strike the anode. Therefore the filament is surrounded by a metal cup, kept at the same potential as the filament. The cup provides an electric field which causes a focusing action on the electrons to produce the desired small target area on the anode
What is Jupiter's terrain?
it has craters and small mountains
How many craters Earth?
There are a huge number of craters on the Earth, including very small impact sites. There are about 65 named and documented craters on the planet.
What is thought to be the reason that there are no small impact craters on Mars?
The wind blows small dust particles, eroding the surface of Mars, erasing small impact craters faster than they can form.
Are craters larger than calderas?
Not necessarily. Some impact craters are quite small, down to only a few meters across. At the other end, some impact craters are far larger than calderas.
What are anode and cathode streamers?
Since streamers are formed b/c of avalanche present in the gap. If the gap is small the transformation occurs only when the avalanche reach the anode and is called Cathode Streamer. If the discharge gap is quite large, over-voltages are large and hence the avalanche transfers from anode to cathode called Anode Streamer.
Why are some craters very small on the moon and others are gig?
because they are different from us
What are the holes in the moon called?
I think there are called craters. I thinks so dont take my word for it.
Can you see craters on the moon from earth?
No. Most of the impact craters that have formed on Earth have been destroyed and buried by geologic processes, processes that the moon lacks. While some recent impact craters on Earth remain visible on the surface, they are too small to be seen from the moon.
Do impact craters often have a little peak in the center?
They often do have a small peak in the center, but not always.
