Matter Vs. Antimatter-They have reversed charge, but sadly not reverse gravity.

Penning traps are a good way to confine charged particles, and often used as a part of antiparticle experiments. But their action relies on the particle's charge, not its spin.
Thanks for your reply Bill.

What I want to do is to find out how to capture and hold antimatter particles for a long time (3-4) month period so that they can be studied by scientific community and in future can be used as an energy source for space travel.

Thanks

Penning traps are a good way to confine charged particles, but there are at least two problems:
  • even in the best vacuum on earth, some particles are present, and eventually your antiprotons will annihilate with them
  • you cannot store relevant quantities of antiprotons (e.g. worth GJ of energy for space travel), as the accumulated charge would lead to a strong repulsion between the trapped particles. You can make neutral hydrogen, but then catching and trapping them is really tricky.
