• What is thermionic emission?

  Emission of electrons due to heat
• What is the role of the cathode electrode in X-ray production?

  It emits electrons when heated

  
• What material is used for the tungsten filament in X-ray tubes?

  Tungsten
• At what temperature does the tungsten filament operate?

  2200 degrees Celsius
• What happens to electrons at the outer energy levels during thermionic emission?

  They gain kinetic energy and are liberated
• What is the purpose of the potential difference (PD) in an X-ray tube?

  To accelerate electrons toward the anode
• What is created in the glass tube of an X-ray tube?

  A vacuum
• What charge does the anode target material have?

  Positive charge
• What is the target material embedded in the anode block?

  Tungsten
• Why is tungsten used as a target material in X-ray tubes?

  It has a high atomic number and melting point
• What occurs during electron interactions in the target?

  Electromagnetic radiation (EMR) is produced
• What are the two types of X-ray production processes described?

  1. Characteristic Radiation
  2. Bremsstrahlung Radiation
• What happens during characteristic radiation production?

  Inner shell electron collision releases EMR

  
• What is the equation for energy release in characteristic radiation?

  BE(k) - BE(L) = EMR X-ray photon
• What occurs during a cascade event in characteristic radiation?

  Orbital electrons fill vacancies and release EMR

  
• What characterizes Bremsstrahlung radiation production?

  No collision occurs; deflection of electrons happens

  
• What does the term "braking" refer to in Bremsstrahlung radiation?

  Deflection and slowing down of incident electrons

  
• What is released during Bremsstrahlung radiation production?

  Electromagnetic radiation (EMR)
• What type of spectrum is produced in Bremsstrahlung radiation?

  Continuous X-ray photon spectrum
