Title: What is the source of hadrons in the LHC?
Post by: Fozzie on 24/11/2009 20:37:11

We hear about them being sent around the ring before colliding but I just wondered how they produce them in the first place. What is the source of hadrons?

Since "hadron" is a term used for a particle that experiences the "Strong nuclear" force, any old proton or neutron is a hadron. However, it would be simplest to have a single charged nucleon for the accelerating field, so a single proton (aka hydrogen nucleus) sounds like the best choice.

Therefore, my guess is that they use hydrogen and ionize it to produce a hadron.

Of, course, my guesses are not always correct  [:I]

I would expect something like that too, to be honest.


Well, it seems the LHC is finally up and running again. How long this time for i wonder...

The LHC also has the facility for accelerating Lead nuclei but I do not believe this has been tested as yet.

I have a hypothetical particle that could possibly be produced in the LHC. It came from the Square-of-the-Shells rule that I stumbled upon in 1991. It will be a neutral composite particle that consists of a bound state of four components. They are:

Shell 4: 913.34128  Mass in MeV
Shell 4: 913.34128
Shell 3: 21.60362
Shell 3: 21.60362


This neutral particle would be hard to detect, since it has a neutral charge. However missing mass may be detected. This neutral particle would also be a candidate for the material composition of neutron stars.

Thanks for that but what I was enquiring about was what is the mechanism which is used to fire the protons? I am familiar with how a cathode works as used in a TV or oscilloscope tube. Is it something like that?
