By performing experiments using three laser systems — Titan at Lawrence Livermore, Omega-EP at the <a href="http://www.lle.rochester.edu/omega_facility/omega_ep/">Laboratory for Laser Energetics</a>&nbsp;and Orion at&nbsp;<a href="http://www.awe.co.uk/what-we-do/science-engineering-technology/orion-laser-facility/">Atomic Weapons Establishment</a>&nbsp;(AWE) in the United Kingdom — LLNL physicist Hui Chen and her colleagues created nearly a trillion positrons (also known as antimatter particles). In previous experiments ...
