Discussion Overview

The discussion revolves around how a high-school student can accelerate electrons using accessible materials, particularly focusing on old technology like CRT televisions. Participants explore practical methods and applications for accelerating electrons, while also considering safety and the implications of such experiments.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant inquires about methods to accelerate electrons without advanced equipment, mentioning an old television filament tube.
  • Another participant suggests that turning on a CRT TV naturally accelerates electrons, questioning the purpose of the acceleration.
  • A participant expresses curiosity about the applications of accelerated electrons, referencing a screen.
  • It is noted that electrons striking fluorescent material can produce light, which is relevant for image formation on screens.
  • Concerns are raised about readiness to accelerate electrons if the purpose is unclear.
  • Another participant emphasizes the importance of understanding the intended use of accelerated electrons before proceeding.
  • A suggestion is made to use neodymium magnets to deflect electrons in a CRT, with a caution about high voltages and a question about predicting deflection based on magnet polarity.
  • One participant recommends researching particle accelerators for foundational concepts related to electron acceleration.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and readiness regarding the acceleration of electrons, with no consensus on the best approach or the necessity of having a clear purpose before experimentation.

Contextual Notes

Participants mention safety concerns regarding high voltages and the need for clarity on the purpose of accelerating electrons, but these aspects remain unresolved in the discussion.

Who May Find This Useful

Now, I'm not a big city physicist like my client here, but if it please the scientific community, I'd reckon I'd like to get some electrons moving.

So here's my question:

How does a high-school student like myself accelerate electrons without access to any serious hardware stores? I read something about using an old television filament tube, and a few electron volts, but I'm a bit fuzzy on the details.

Thanks In Advance.

P.S. Keep in mind, I haven't tried this before, so don't get too complicated.
 
Physics news on Phys.org
Turn on your old CRT TV and you got electrons being accelerated. The question is, what do you want to do with it?
 
I didn't do the stupid country roob post beginning for nothing. What can I do with electrons once there moving? I read about something involving a screen.
 
As electrons hit fluorescent material it emits light. This property can be used to form an image on a screen.
 
If you aren't sure what to do with the electrons once you get them moving, you probably aren't ready to accelerate them.
 
Just say why you want to accelerate them? there are many ways...
 
Put a pair of neodymium iron boron permanent magnets near the neck of the tv tube (CRT) and deflect them. [Beware of exposed high voltages]. The deflection of the spot in the center of the fluorescent screen is perpendicular to the magnetic field. If the magnets are strong enough, you may also be able to hold the magnets in front of the screen and deflect the electrons. If you can determine a priori what the polarity of the magnets are, can you predict which way the deflection is?
 
If you just look up particle accelerators on google and the basic ideas should make sense
