The radial Time projection chamber will measure the position ofanti-hydrogen annihilations by detecting the trajectories of particlesproduced in the annihilation reactions. This will be used to study thegravitational force on antimatter in the Alpha-g experiment.

Welcome!
ALPHA (Antihydrogen Laser Physics Apparatus) is an international collaboration based at CERN, and which is working with trapped antihydrogen atoms, the antimatter counterpart of the simplest atom, hydrogen. By precise comparisons of hydrogen and antihydrogen, the experiment hopes to study fundamental symmetries between matter and antimatter.
