After repeated pounding,antihydrogen reveals its charge:zero
repeated pounding antihydrogen charge zero
2016/2/22
An eight-hour experiment using the ALPHA trap at CERN confirmed with 20 times greater precision than before that the charge of the antihydrogen atom – the antimatter counterpart of the hydrogen atom –...
A reliable cw Lyman-$α$ laser source for future cooling of antihydrogen
Lyman-alpha Four-wave mixing Antihydrogen
2011/8/29
We demonstrate a reliable continuous-wave (cw) laser source at the 1 S–2 P transition in (anti)hydrogen at 121.56 nm (Lyman-α) based on four-wave sum-frequency mixing in mercury. A two-photon resonanc...
The main goal of the AEGIS experiment at the CERN Antiproton Decelerator is the test of fundamental laws such as the Weak Equivalence Principle (WEP) and CPT symmetry. In the first phase of AEGIS, a b...
Physicists at CERN have taken a big step towards making the first spectroscopic measurements on a beam of antihydrogen atoms. The antihydrogen atoms, which consist of an antielectron orbiting an antip...

Physicists at CERN in Geneva are the first to capture and store atoms of antimatter for long enough to study its properties in detail. Working at the lab's ALPHA experiment, the team managed to trap 3...
Antihydrogen formation dynamics in a multipolar neutral anti-atom trap
Antihydrogen CPT Non-Neutral Plasma Particle Transport
2010/3/15
Antihydrogen production in a neutral atom trap formed by an octupole-based magnetic field minimum is demonstrated using field-ionization of weakly bound anti-atoms. Using our unique annihilation imagi...
