Well the main goals of the Alpha experiment has always been the creation and trapping of antimatter. I went to a seminar by one of the collaborators
and it was a very interesting and amazing concept on how to mix and hold onto antimatter. The main challenges are cooling and containment.
You create both the anti-protons and the positrons using accelerators, Positrons can be made in another way though if memory serves, they still use an
accelerator. You then need to cool both, and by cool i mean slow them down while maintaining them in packets. This is quite tricky, more so than
Once this is done, the two are pushed into a storage well, basically you try and create a magnetic potential that will hold onto the positrons, and
anti protons, you allow the positrons to fill an inner potential and then you allow the anti-protons to oscillate through them (i think using RF) but
basically the efficiency of the trapping is all to do with the cooling of the two groups and the controlled mixing such that you end up with
anti-matter contained within a penning trap that have little momentum.
The experiment went from trapping a handful for a minute amount of time, to trapping thousands for periods of seconds, it hink now even greater...
very very interesting experiment.
