Term
projectile electrons
Definition
electrons traveling from cathode to anode
Term
what happens when electrons hit the heavy metal atoms of the target
Definition
they transfer their kinetic energy to the target atoms
Term
projectile electrons interactions result in
Definition
kinetic energy being converted to thermal and electromagnet in the form of infared radiation and x-rays
Term
what happens when projectile electrons don't transfer enough energy to ionize the target atoms
Definition
the outer shell electrons are simply raised to an excited, or higher, energy level
Term
what happens with the emission of infared radiation
Definition
outer shell electrons immediately drop back to their normal energy level
Term
how is heat production related to tube current
Definition
they are directly related
Term
what is produced when projectile electrons interact with inner-shell electrons of the target
Definition
characteristic x-rays can be produced
Term
why is it called characteristic x-radiation
Definition
because it is characteristic of the target element
Term
what causes characterstic x-rays to be emitted
Definition
when an outer-shell electron fills an inner-shell road
Term
which shell of the tungsten atom is the only one that is useful for imaging
Definition
k-shell
