Production of Anti-Protons | LHC

[FunkyDwarf]

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.
