Question

how to store antimatter?​

Answer 1

Answer:

The Antiproton Decelerator established at CERN in the late 1990s began providing slower moving, lower-energy antiprotons for antimatter experiments. In these experiments, electric and magnetic fields hold the antiprotons separate from positrons in a near-perfect vacuum that keeps them away from regular matter.

Answer 2

• It is very difficult to contain antimatter. Any contact between a particle and its anti-particle leads to their immediate annihilation: their mass is converted into pure energy. To contain anti-particles, therefore, you have to isolate them from all particles.
