How can we make antimatter? - BBC Science Focus Magazine
At CERN, physicists make antimatter to study in experiments. The starting point is the Antiproton Decelerator, which slows down antiprotons so that physicists can investigate their properties. The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms.
The main idea in making antimatter is just getting enough energy in a collision to allow the particles to be made. If you get electrons going fast enough and throw them at a piece of material called a target, preferably made out of atoms that have a large atomic number, you will have a shower of electrons, positrons (anti-electrons) and photons.
Learn how antimatter is produced and trapped at CERN, and why it is so expensive and rare. Find out how antimatter is related to the movie Angels & Demons and the story of Vetra.
The way to solve the baffling disappearance of antimatter, and to learn more about this substance in general, is by studying both particles and antiparticles to find and decipher the subtle clues. Click the link below to read more about Antimatter in CMS
The antimatter counterpart to the simplest atom, hydrogen, is a neutral antihydrogen atom, which consists of a positively charged positron orbiting a negatively charged antiproton. In 1995, physicists at CERN announced that they had successfully created the first atoms of antihydrogen at the Low Energy Antiproton Ring (LEAR).
