shorter 

in electron 3 the x-ray produced by this interaction would be_______ than electron two .

highest

The resultant x-ray of number 2 would have_________ wavelength than all other electron

shortest 

id the 100 keV electron shown below interacts with an atom and the KE recoded to 40 keV, what’s the keV of the produced xray

Why is it less likely for high energy bremsstrahlung x-rays to be produced then lower energy x-rays

Less likely to hit bull's-eyes

In the atoms of the an target, if an inner shell electron is ejected by a direct collision from an incident electron, what x-ray producing interaction will follow

Characteristic radiation

When an electron falls from outside the atom into a particular shell, the characteristic x-ray produced will have a KEB equal to _________ energy that shell.

Binding

The particular element used

The x-ray emission spectrum represents? What does the amplitude represent?

a plot of the number of x-rays produced and average energy

Three minutes

The process in which electrons have been boiled off the filament is called

thermonic emission

The electrons boiled off of the filament are attracted to what

Anode

Why is the x-ray tube enclosure enclose and lead?

To prevent leakage

What is the legal limit for leakage radiation?

1 mGy/hr

Why is the glass envelope of the x-ray tube designed to form a vacuum?

To prevent slowing down

The x-ray tube envelope is composed of a heat resistant material called

Pyrex glass

What two components are considered a part of the cathode assembly

Filament and focusing cup

Why is tungsten used in an anode

Atomic number, thermal, conductivity, high melting point,

When are the MA stations activated in the filament boils of electrons

When rotor is engaged

When exposure button is pushed

In an x-ray to electromagnetic induction is used what is located on the outside of the glass and inside

Stater-outside rotor-inside

What part of the x-ray tube is made of thorium impregnated tungsten

Filament

Which area would be defined as the area of heat desperation on the x-ray

Focal spot

The difference in charge between the cathode and unnoticed during an exposure is called

Potential difference

Tungsten is the principal material used in

Anode disc and filament

The material often added to a rotating disk to reduce service defects and improve rotational balance is

Rhenium 

The efficiency and lifespan of the filament wire is improved by the addition of

Thorium

What portion of the induction motor that operates within the vacuum of the enclosed x-ray tube?

Rotor

As an x-ray tube ages, the inside can become coded with tungsten which can cause

Arching

smaller 

the heel effect is caused by

presence of anode disc

the fact that the effective focal spot is smaller than the actual focal spot is known as

line focus principle

what is the benefit of the line focus principle

increase spatial resolution and heat capacity

what is an advantage of an rotating anode?

more surface area to distribute heat
