Lawrence Livermore National Laboratory (LLNL) scientists have achieved a near 100 percent increase in the amount of antimatter created in the laboratory.

Using targets with micro-structures on the laser interface, the team shot a high-intensity laser through them and saw a 100 percent increase in the amount of antimatter (also known as positrons). The research appears in Applied Physics Letters.

Previous research using a tiny gold sample created about 100 billion particles of antimatter. The new experiments double that.
