#1
Which component of the x-ray tube is responsible for producing electrons?
Cathode
ExplanationCathode produces electrons through thermionic emission.
#2
What is the purpose of the anode in an x-ray tube?
To convert kinetic energy into x-rays
ExplanationAnode converts kinetic energy of electrons into x-rays upon collision.
#3
Which material is commonly used for the filament in an x-ray tube?
Tungsten
ExplanationTungsten is used due to its high melting point and durability.
#4
Which material is commonly used for the anode in an x-ray tube?
Tungsten
ExplanationTungsten is used due to its high atomic number and melting point.
#5
What is the function of the glass envelope in an x-ray tube?
To provide electrical insulation
ExplanationGlass envelope insulates the components, preventing electrical discharge.
#6
What is the purpose of the focusing cup in an x-ray tube?
To focus the electron beam onto the anode target
ExplanationFocusing cup directs the electron beam towards the anode with precision.
#7
Which parameter determines the maximum energy of the x-rays produced in an x-ray tube?
Anode voltage
ExplanationAnode voltage directly influences the energy of emitted x-rays.
#8
In what form is the target material typically deposited on the anode?
Coating
ExplanationTarget material is often deposited as a thin coating on the anode surface.
#9
What is the function of the tube housing in an x-ray tube?
To provide electrical insulation
ExplanationTube housing prevents electrical shocks and maintains vacuum.
#10
What effect does increasing the tube current have on x-ray production?
Increases the number of x-rays produced
ExplanationHigher tube current generates more electrons, leading to increased x-ray production.
#11
What is the purpose of the vacuum inside the x-ray tube?
To prevent arcing
ExplanationVacuum prevents electron dispersion and arcing between components.
