6. Great Video. For intraoral dental xray tube, it uses oil (smell like engine coolant). Do you know what kind of oil? Is the enclosure vacuum? In that case if the cathode dies, is it impossible to replace it?
7. great video! saved the time of reding endless explanations
8. helpful for physics student
9. Thank you for the videos.
10. great explanation. love this video. you just helped me with my assignment. thanks very much :-)
11. Why an electric current is applied to the cathode filament?
12.  if we increase the heating current across the negative electrode, does that increase the number of emitted electrons?
13. So the death ray is true! Thank God, I don't want my kids invaded by anybody! 
14. thanks for this video it was very helpful but can i get the link of the video that talks about the interaction that happens at the level of the anode please ?
