Hi
why scientists picked up proton for LHC?
why scientists picked up proton for LHC?
Is accelerating antiproton incrementally easier because of free electrons in the cavities, or for some other reasons ? For the remainder of the technical difficulties, I gather that only the production is more challenging, especially if you are interested in luminosity.Vanadium 50 said:Accelerating antiprotons is no harder than accelerating protons (it's actually incrementally easier).
humanino said:Thanks Vanadium and Astro for your answers.Is accelerating antiproton incrementally easier because of free electrons in the cavities, or for some other reasons ?
Ah, I see what you meant, thank you for the precision. However, nothing in principle (except cost of course) prevents you from doing the same with protons !Vanadium 50 said:It's because the emittance - essentially, the size of the beam - is smaller for antiprotons than for protons. Antiprotons sit in an accumulator for ~24 hours, continually being cooled, but protons come out of a bottle. So you have better initial beam quality for the antiprotons, and that is (like I said, incrementally) helpful.

Why other collisions are not pretty clean?Astronuc said:and comparatively a proton-proton collision is pretty clean.
The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator. It is located at the European Organization for Nuclear Research (CERN) in Switzerland and it was built to study the fundamental building blocks of matter and the forces that govern them. The LHC is important in studying protons because it allows scientists to accelerate protons to incredibly high energies and collide them together, providing insights into the mysteries of the proton.
The LHC uses powerful magnets to accelerate protons to nearly the speed of light. These protons are then directed to collide with each other in designated areas within the collider. The collisions release an enormous amount of energy, which allows scientists to study the resulting particles and their interactions. By analyzing the data from these collisions, scientists can gain a better understanding of the internal structure and behavior of protons.
One of the main mysteries surrounding protons is the origin of their mass. According to the Standard Model of particle physics, protons should be massless, but they actually have a significant amount of mass. The LHC is helping to investigate this mystery by studying the Higgs boson, a particle believed to give mass to other particles. The LHC is also studying the strong nuclear force, which is responsible for holding protons together in the nucleus of an atom.
While the primary goal of the LHC is to advance our understanding of the universe, the knowledge gained from studying protons could also have practical applications. For example, the technology developed for the LHC, such as advanced computing and data analysis techniques, could be used in other fields such as medicine and engineering. Additionally, the LHC may help us better understand the behavior of protons in extreme conditions, which could have implications for future energy production and storage technologies.
The LHC has undergone extensive safety reviews and has been deemed safe by the scientific community. The energy levels and collisions produced in the LHC are similar to those that occur naturally in space, and the collider has multiple safety systems in place to prevent any potential hazards. Additionally, all experiments conducted in the LHC undergo rigorous ethical and safety evaluations before being approved.
