Increased efficiency Antimatter production

In summary: It was studied of course, but the advantage per collision (some events have a higher probability to occur) would be small compared to the huge disadvantage of a lower collision rate.It would take a heck of a lot of proton-antiproton collisions to make a significant impact on LHC performance.

Hi

Does anyone know of any papers about Increased efficiency Antimatter production, as I am interested in this area.

Apologies if it's in the wrong area. Thanks.

Antiprotons, neutral antihydrogen, or more exotic antimatter? The paper @rootone linked is about adding a positron to antiprotons. Here is a follow-up discussion, freely accessible.

For antiproton production, shooting high-energetic protons at a target and trying to capture as many antiprotons as possible is the most efficient way we have available. Maybe some results from MICE, a muon cooling experiment, can also be applied to antiprotons.

It would be interesting to know how the antiprotons get contained at the LHC until they need to be used.

Reading on this process, I have learned that 2 high-energy protons are converted into 3 protons and an antiproton. Does the extra proton and antiproton come from the "high energy" being converted into mass?

The LHC does not use antiprotons.

There are other CERN accelerators which capture and slow them down for research.
Synchrotons can store protons and antiprotons in the same way, you just have to reverse the magnetic fields.

Yes.

Well, it's not a bad idea if it could be possible.

I say let's call up our friends in Geneva and tell 'em!

It wouldn't help much at the LHC energies, and it would lead to a much lower luminosity as you can't get as many antiprotons as you can get protons.

Tevatron and SPS, which ran at a much lower energy, used proton-antiproton collisions.

Why not though?, I guess that is work in progress

It's a terrible idea. Apart from the problem that the beam design won't work, switching to antiprotons gets you less beam, and therefore fewer interesting events. There is a reason why this was considered for the LHC - and rejected.

OK fair enough, no chance of an antimatter destroyer of the robot controllers then,
/jk. /sorry

You get protons out of a hydrogen bottle.
We don't have an antihydrogen bottle.

It was studied of course, but the advantage per collision (some events have a higher probability to occur) would be small compared to the huge disadvantage of a lower collision rate.

OK got it, thanks.
 

1. What is antimatter?

Antimatter is a type of matter that is made up of particles with the same mass as their corresponding particles in regular matter, but with opposite charge. For example, the antiparticle of an electron is a positron, which has the same mass as an electron but a positive charge. When antimatter and matter come into contact, they annihilate each other, releasing a large amount of energy.

2. Why is increased efficiency in antimatter production important?

Antimatter has the potential to be a powerful energy source, as it produces more energy per unit mass than any other known fuel. However, it is currently very difficult and expensive to produce, so finding ways to increase efficiency in production is crucial in order to harness its potential for energy generation and other applications.

3. How is antimatter currently produced?

Antimatter is produced through high-energy collisions between particles, typically protons and antiprotons, in particle accelerators. These collisions create small amounts of antimatter, which must then be carefully collected and stored for later use.

4. What are some potential methods for increasing efficiency in antimatter production?

Scientists are exploring a variety of methods for increasing efficiency in antimatter production, such as using more powerful and precise particle accelerators, developing new techniques for collecting and storing antimatter, and finding ways to reduce the energy required for production.

5. What are the potential benefits of increased efficiency in antimatter production?

In addition to the potential for antimatter to be used as a powerful energy source, increased efficiency in production could also lead to advancements in other fields such as medicine and space travel. Antimatter has the potential to be used in medical imaging and cancer treatment, as well as in propulsion systems for spacecraft. It could also help scientists further understand the fundamental laws of physics and the origins of the universe.
