1. What produces x-rays?
Answer: ✔✔ Characteristic and Bremsstrahlung interactions
Explanation:
X-rays are produced by two main interactions:
o Characteristic interactions: When a filament electron knocks an
inner-shell electron out of the atom, causing the atom to become
unstable. An electron from a higher energy shell fills the vacancy,
emitting a characteristic x-ray photon.
o Bremsstrahlung interactions: When a filament electron is slowed
down or deflected by the nucleus of a target atom, losing energy in the
process, which is emitted as a Bremsstrahlung photon (also known as
"braking radiation").
2. When filament electrons enter the anode target, what do they mostly
interact with?
Answer: ✔✔ Outer shell electrons of tungsten atoms
Explanation:
Filament electrons (from the cathode) typically interact with the outer shell
electrons of the tungsten atoms in the anode. Since outer shell electrons are
less tightly bound to the nucleus, they are more likely to be displaced by the
incoming electrons, leading to Bremsstrahlung interactions or the
, emission of characteristic x-rays when the vacancy is filled by an electron
from a higher shell.
3. What is the result of a filament electron knocking a K-shell electron from a
tungsten atom?
Answer: ✔✔ A characteristic x-ray photon
Explanation:
If a filament electron knocks out a K-shell electron (the inner most shell)
from a tungsten atom, the atom becomes unstable. This vacancy is filled by
an electron from a higher shell (like the L or M shell), and as this electron
drops to a lower energy level, the energy difference is released as a
characteristic x-ray photon. The energy of this photon depends on the
binding energy difference between the two shells involved.
4. The energy of the characteristic x-ray photon is dependent on what?
Answer: ✔✔
1. The binding energy of an inner shell electron
2. The energy level of the filament electron
3. The shell of the electron that is dropping into the newly created
vacancy
Explanation:
The energy of the characteristic x-ray photon depends on:
1. Binding energy of the inner shell electron: The energy required to
remove the electron from the shell.
2. Energy level of the filament electron: The energy of the incoming
electron from the cathode. A higher energy filament electron can
produce higher energy characteristic x-rays.
3. The shell of the electron that fills the vacancy: The energy of the
characteristic x-ray is also determined by the difference in binding
