does anyone know anything else about the antimatter created at CERN besides whats stated in "Angels and Demons"? I thought it was very interesting

High energy physics consists of accelerating particles close to the speed of light and slamming them into each other. This converts the energy back into matter according to E = mc2 when you solve for m.
Every reaction of this kind produces matter and antimatter in equal quantities. The antimatter does not last long on our world. It follows a spiral path before it is annilated. This is because we live in a world full of matter. If you could collide the particle beam in outer space, free from any matter, you could probably save more of the antimatter.
Have you ever heard of a PET scan? The P stands for positron. That is the antimatter equivalent of an electron.
The interesting thing about creating antimatter at CERN is not that happens, but why didn't it happen when our universe was born? Why is there no free antimatter in our universe? All nuclear reactions that convert energy to matter create both matter and antimatter in equal quantities, so our universe should be full of antimatter.
A universe with half and half matter and antimatter would be pretty chaotic, all bright and fiery. It would be a lousy place to live.

In particle physics, antimatter is matter that is composed of the antiparticles of those that constitute normal matter. If a particle and its antiparticle come into contact with each other, the two annihilate; that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc2. This gives rise to high-energy photons (gamma rays) or other particle–antiparticle pairs. The resulting particles are endowed with an amount of kinetic energy equal to the difference between the rest mass of the products of the annihilation and the rest mass of the original particle-antiparticle pair, which is often quite large.
If you Google it, you'll get millions of responses.
If you liked"A&D," you might like "Deception Point," same author.

CERN is a very expensive particle accelerator. They shoot particular particles very close to the speed of light and make them collide. If the collision is just right, you'll get an anti-particle. At CERN, they've found a way to store up these particles. Using a magnetic field, they suspend the particles, so that it doesn't touch the sides of its storage module, and annihilate.
Fortunatly for us, this process of making anti-matter is so very inefficient, it would take billions of years to make 1 oz. of anti-matter using the current methods. That is good, because 1 oz. of anti-matter annihilation releases hundreds of times more energy than a hydrogen bomb. We don't want to make anti-matter!!!

No, it has not been created in such large quantities and it still cannot be contained.

i know that an anti-hydrogen atom has been created, but not much more than that

don't forget that it's a fiction book- treat it as such
