• What should students read about in relation to X-rays?

  Resources on radiation and history of X-rays
• What are the learning outcomes for X-ray production?

  • Label a Stationary Anode X-ray tube
  • Understand thermionic emission
  • Differentiate between Characteristic and Bremsstrahlung radiation
• What is thermionic emission?

  Process where electrons are liberated from a heated filament
• What is the difference between Characteristic Radiation and Bremsstrahlung radiation?

  Characteristic involves electron collisions; Bremsstrahlung does not
• What is the main component of a thermionic emission device?

  Cathode electrode
• What material is the filament in a thermionic emission device made of?

  Tungsten
• At what temperature does the tungsten filament operate?

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

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

  It accelerates electrons toward the anode
• What is the purpose of the glass tube in an X-ray device?

  To create a vacuum for electron flow
• What is the target material in an X-ray tube?

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

  It has a high atomic number and melting point
• What occurs during the inner shell electron collision in X-ray production?

  BE(k) - BE(L) = EMR X-ray photon

  
• What happens to an orbital electron during a cascade event?

  It gains kinetic energy and creates a vacancy
• What is the main characteristic of Bremsstrahlung radiation?

  It involves no collision, just deflection
• What does the term "braking" refer to in Bremsstrahlung radiation?

  Deflection and slowing down of incident electrons

  
• What is released during the Bremsstrahlung process?

  Electromagnetic radiation (EMR)
• What are the components involved in X-ray production?

  • Cathode electrode
  • Tungsten filament
  • Potential difference (PD)
  • Target material (Tungsten)
  • X-ray tube device
• What are the differences between Characteristic Radiation and Bremsstrahlung radiation?

  Characteristic Radiation:

  • Involves inner shell electron collisions
  • Produces discrete X-ray photons

  
  

  Bremsstrahlung Radiation:

  • No collisions, only deflection
  • Produces a continuous X-ray spectrum
