Can we contain anti-matter?

[Aerozord]

Obviously just having anti-matter in sizable quantities existing at all on the planet is dangerous. But do we have the technology to capture and contain it?

I know we can make it, particle accelerators make it as a bi-product and could be fine tuned for that specific purpose. Now I do know even a 100% efficient one would be pointless since the energy you'd get out of the reaction would be equal to the energy it took to make it. There is the ability to make it into a weapon, but I wanted a productive use.

Was thinking, bulk of rocket fuel is used to lift the rest of the fuel. Anti-matter would save alot of fuel since its a very highly condensed energy source.
