Where to Find Energy in Joules of Particle Accelerators

Click For Summary

Discussion Overview

The discussion centers around the energy of particle accelerator beams measured in Joules, with a focus on finding comprehensive data for various active particle accelerators. Participants explore methods to calculate or locate this information, while also engaging in a broader conversation about the implications of particle accelerator energy in relation to geological phenomena, specifically earthquakes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks a method or resource to find the energy of various particle accelerators in Joules, noting that only the LHC and RHIC energies are readily available.
  • Another participant suggests that the total energy can be calculated by multiplying the energy per particle by the number of particles per bunch and the number of bunches.
  • Some participants assert that the LHC has the highest energy stored in its beams and magnets compared to other accelerators.
  • A participant mentions a project mapping energy radii of particle accelerators in relation to earthquake activity, referencing an article linking the LHC to earthquakes in Nepal.
  • Several participants challenge the validity of the connection between particle accelerators and earthquakes, labeling such claims as "crackpot nonsense" and questioning the relevance of the proposed mapping.
  • There is a discussion about the number of operational particle accelerators, with one participant noting that there are about 30,000 in total.
  • Some participants express skepticism about the feasibility and seriousness of linking particle accelerator activity to geological events.
  • A later reply suggests that while exploring the topic could be entertaining, it should not be taken seriously.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the relevance and validity of linking particle accelerators to earthquake activity. While some participants provide technical insights on calculating energy, others dismiss the earthquake claims as unfounded. No consensus is reached on the implications of the energy of particle accelerators.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the energy calculations and the definitions of terms related to geological impacts. The scope of the discussion is also restricted to the major particle accelerators and does not encompass all operational accelerators.

I am looking to find the energy of particle accelerator beams in Joules, as the energy given in the URL here:
http://en.wikipedia.org/wiki/List_of_accelerators_in_particle_physics

only gives the energy of each proton. I am looking at all the particle accelerators still active today, and I have only found the energy per beam in joules for the LHC and the RHIC. Is there an equation or reasoning I can use to find the answer or a website with a chart or information of all the energies per beam in joules? Thank you! The URL's for the LHC and RHIC energy are listed below:

It's energy per particle time the number of particles per bunch times the number of bunches. You'll probably have to go to the site of each accelerator to get those numbers.
 
If you are just interested in the record: the LHC has by far the most energy stored in the beams.
And even more stored energy in the magnets.
 
I know that part but I'm mapping out energy radii of every particle accelerator to see if they can cause earthquakes for an English essay. I read an article about the LHC being connected to earthquakes in Nepal so I made a map of all the particle accelerators active today and the fault lines of the planet and want to draw a radius of how far the beams' energy would go out of the accelerator when gotten rid of.
 
That topic does not make sense at all.

Not at all, they stop in beam dumps that are a few meters long. Muons can get a bit further, maybe 100 meters - so what. The total energy in the beams is completely negligible in terms of geology as well.

You can find crackpot stuff for everything, that does not mean it would be relevant in any way.

Crackpot nonsense.

See http://en.wikipedia.org/wiki/List_of_earthquakes_in_2015. Do you see a change in the number of earthquakes coincident with LHC running? I sure don't. Furthermore, there are about 30,000 accelerators in operation. Are you going to include them all in your essay?
 
I included the major ones. And I don't believe it, I just wanted to show how even if what they're saying is happening, the accelerators won't cause earthquakes. I already saw that there are actually less earthquakes in recent years compared to earlier ones

No, you included the famous ones.

Imagination is good up to a point... After that the mind gets sick and life becomes a fairytale... I can't understand how the minds of the people who wrote it work... Even if there were to be earthquakes, they should have been near the LHC and not to the other side of the Earth (probably they don't know geography, and think Nepal is a region somewhere in Europe or even a city, and confuse Himalayas for the Swiss Alps). Even if that was not the problem, then we get strikes from cosmic rays, how would some extra events with low intensity (have to travel through the whole earth??) cause such an earthquake?

And manage to go backward in time. The 7.8 magnitude earthquake in Nepal was before LHC collisions.

Like I said, it's crackpot nonsense.

This topic is sillier than the lawsuit to stop the LHC due to black holes destroying the earth.

There are thousands of particle accelerators in this world. Your doctor's office may even have one! Unless there is a legitimate physics that links accelerators and earthquakes, this is crackpottery and should be dealt with accordingly by our forum rules.

Well it would be "just for fun" to work this out and see what you find, but for sure not taken seriously...
