X ray production - doubts in the principle involved

Click For Summary
SUMMARY

X-ray production involves the ionization of air molecules within a tube due to a high electric field, leading to the emission of electrons from the cathode upon collision with positive ions. The underlying principle is based on energy transfer during collisions, where if the energy exceeds the ionization energy of the cathode material, electrons are released. This process predates the development of the Coolidge tube, which revolutionized X-ray technology.

PREREQUISITES
  • Understanding of ionization energy and its significance in electron emission
  • Familiarity with the principles of electric fields in vacuum tubes
  • Knowledge of the historical context of X-ray technology, particularly the Coolidge tube
  • Basic concepts of atomic structure and electron behavior
NEXT STEPS
  • Research the mechanics of electron emission in vacuum tubes
  • Study the design and function of the Coolidge tube in X-ray production
  • Explore the relationship between energy transfer and ionization in atomic collisions
  • Investigate modern advancements in X-ray technology and their principles
USEFUL FOR

Physics students, radiology professionals, and anyone interested in the principles of X-ray production and the evolution of X-ray technology.

X ray production -- doubts in the principle involved

Homework Statement



In x ray production, air molecules are ionised due to presence of very high electric field within the tube and positive ions are attracted to the cathode C and due to their impact electrons are emitted from the cathode.
I have a doubt in this. What is the underlying principle in which positive ions on collision with cathode, electrons coming out of cathode.

Homework Equations


The above scenario was before the advent of Coolidge tube.

The Attempt at a Solution

 
Physics news on Phys.org


When positive ions collide with cathode then they collide with atoms transferring energy.When this is greater then ionization energy then electrons are released.
 


I don't understand Bhaskar. Could u elaborate more, pls?
