SUMMARY

The discussion centers on the construction of a tabletop electron accelerator, specifically referencing a demonstration in Paris. Participants highlight the challenges of creating such a device, noting that it resembles a circular cathode ray tube (CRT) where electrons circulate but are ultimately dumped at the injection site. The conversation emphasizes the dangers associated with high voltage, vacuum systems, and x-ray emissions, advising against home construction without proper expertise. As a result, the thread was closed due to safety concerns regarding the lack of knowledge among participants.

PREREQUISITES
  • Understanding of high voltage systems
  • Knowledge of vacuum technology
  • Familiarity with electron beam physics
  • Experience with radiation safety protocols
NEXT STEPS
  • Research safe practices for high voltage experiments
  • Learn about vacuum chamber construction techniques
  • Study electron beam generation and manipulation
  • Explore radiation safety measures and regulations
USEFUL FOR

This discussion is beneficial for physicists, engineering students, hobbyists interested in particle physics, and anyone considering building high-voltage electron devices safely.

That doesn't look like it would accelerate anything in the ring. It is like a CRT in circular shape: the electrons go around the ring once and get dumped at the injection site, because you have no way of combining the circulated electrons with the new injection beam without much more fancy hardware and control systems. There are websites describing how CRT-like things can be built, but they are dangerous due to high voltage, vacuum, and x-rays - it is not a good idea to do that at home unless you know exactly what you are doing. Based on your post, you don't have the required knowledge to do that safely, therefore I closed the thread.
