Billions Of Particles Of Anti-Matter Created In Laboratory
Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear.
The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma “jet.”
This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts.
Anti-matter research also could reveal why more matter than anti-matter survived the Big Bang at the start of the universe.
“We’ve detected far more anti-matter than anyone else has ever measured in a laser experiment,” said Hui Chen, a Livermore researcher who led the experiment. “We’ve demonstrated the creation of a significant number of positrons using a short-pulse laser.”
