Discussion Overview

The discussion revolves around the feasibility and safety of constructing a linear accelerator (linac) that accelerates ionized gas or electrons, with the intention of directing them towards a target such as a phosphor-coated screen or a Faraday cup. The inquiry touches on aspects of accelerator physics, safety concerns, and practical limitations related to vacuum conditions and budget constraints.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant expresses a desire to construct a linac and acknowledges challenges related to vacuum conditions and the complexities of using magnets for acceleration.
  • The same participant mentions a limited understanding of accelerator physics but is eager to learn and overcome obstacles.
  • Another participant warns that lack of knowledge in this area could lead to serious injury or death, urging caution.
  • A different participant claims to have experience with electronics and safety measures related to vacuum systems, questioning the viability of building a linac within a specified budget.
  • Concerns are raised about misconceptions regarding the use of magnets in linac design, suggesting that such misunderstandings indicate insufficient knowledge for safe construction.

Areas of Agreement / Disagreement

Participants express significant disagreement regarding the safety and feasibility of constructing a linac without adequate knowledge. Some participants emphasize the dangers involved, while others seek to explore the hypothetical aspects of the project.

Contextual Notes

Participants highlight limitations in knowledge and experience, as well as the potential risks associated with constructing high-energy physics experiments. There are unresolved questions about the technical requirements and safety protocols necessary for such a project.

Hello everyone,


I'd like to say hello to all the fellows here at PF, I've been reading threads in the forum for the longest time, and have joined up today.


My inquiry is of the viability of constructing a sort of linac that accelerates ionized[gas], or electrons from an electron gun and ends up hitting (possibly a phosphor coated screen) a block, or though expensive, a Faraday cup. I understand the issues of less-than-ideal vacuum conditions, and especially in the case of the Beta particle, it is a requirement for anything in particular to happen. Getting magnets to work in unison to do any type of accelerating also has it's complexities to work out.

I've read for about a week now on the matters in accelerator physics than hanging around HEP Experiment section of arXiv.org for hours, so my intuition is extremely limited, but I'm eager to overcome this temporal roadblock.


I've seen some posts on here, and I sincerely apologize for any hint of overambitious perspectives or of the sort; I just want others input.

Thanks.

My second post must have thrown you off:
I have experience with electronics, and playing with NST's, MIG welders, and AC sockets. I work at an airport shop, and use nitrogen bottles regularly, so anything to do with the vacuum is only under 14.7 PSI(compared to 3000 PSI). A polycarbonate tube would suffice for the vacuum cavity and would set any safety concerns-essentially-aside.

The incompetence I hold is the viability of building a small-scale linac under a $2000-$3000 budget.


What are some implications with the idea? How about it as a hypothetical question?
 
If you think a Linac uses magnets to accelerate, you don't know anywhere near enough to do this safely. The fact that you think you do makes you more dangerous, not less.

Thread closed - we do not discuss dangerous activities here.
