In summary, antiprotons are produced at the Large Hadron Collider (LHC) through hadron collisions and then separated from other particles. This process is also used at other particle accelerators, such as the Tevatron at Fermilab. At CERN, the Antiproton Decelerator and Super Proton Synchrotron are used to produce and increase the energy of antiprotons for experiments.

Hey

I was just wondering anyone knew the mechanisim (specific if you got it) by which they create the antiprotons for say use at the LHC.

Cheers

You don't use antiprotons in LHC..

But here are some information about antiproton production (mainly its done by hadron collisions, then you separate the antiprotons from the rest of the particles)

(The Tevatron at Fermilab uses antiproton in collisions)

The mechanism is often:
proton + lead target -> Sum of hadrons

seems to suggest they do use them at the LHC, or at least produce them there
he Antiproton Decelerator will produce a beam of anti-protons at 2 GeV, after cooling them down from 3.57 GeV. Finally the Super Proton Synchrotron Super Proton Synchrotron

The Super Proton Synchrotron is a particle accelerator at CERN . ...

can be used to increase the energy of protons up to 450 GeV.


Cheers for links!

Well of course they produce and do experiemnts with antiprotons at CERN, but LHC is still a good ol 'proton-proton collider ;-)

CERN is more than the LHC.

Here is more info about their antiparticle experiemnts

Basically, you send protons into a target and collect the negative particles produced. You put them in a storage ring and the unstable particles - everything except antiprotons and electrons -decay. The electrons lose energy through synchrotron radiation so after a while you're left with antiprotons and nothing else. You can then cycle the system again.

Lather, rinse and repeat.

1. What is the LHC and how does it produce anti-protons?

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator. It works by accelerating protons to nearly the speed of light and then colliding them together. When these collisions occur, they produce a variety of particles, including anti-protons.

2. How are anti-protons detected at the LHC?

The LHC has a complex system of detectors that are designed to track and measure particles produced in collisions. Anti-protons are detected by their unique signatures, such as their charge and energy, which are recorded and analyzed by the detectors.

3. Why is the production of anti-protons important?

Anti-protons are important because they are the antiparticles of protons, which are the building blocks of atoms. Studying anti-protons can provide valuable insights into the fundamental laws of physics and the structure of matter.

4. What are the potential applications of anti-protons?

Anti-protons have many potential applications, such as in medical imaging and cancer treatment. They can also be used to create and study antimatter, which could potentially be used as a powerful source of energy.

5. Are there any risks associated with the production of anti-protons at the LHC?

There are no known risks associated with the production of anti-protons at the LHC. The LHC is designed and operated with strict safety measures in place to ensure the protection of both the scientists and the environment.
