The electron hits the quark, and you try to take a quark out using that energy.
When an electron hits the screen it make a phosphor glow there.
The number of ionization depends upon the probability that an electron hits an ion.
When the electrons hit the target, X-rays are created by two different atomic processes:
The electrons hit the molecules, causing the molecule to fragment in a characteristic way that can be repeated.
When an electron hits the surface, it may be reflected (backscattered), absorbed, or conducted away.
When these electrons hit the phosphor screen, they cause that small part of the screen to light up.
The interaction of the moving electron beam with the magnetic field causes the electrons to shift slightly and hit the wrong color dots.
These electrons in turn hit other atoms causing an avalanche of electrons.
In this case electrons simply hit the metal plate/cup and a current is produced.
