Welcome to the ASACUSA homepage

ASACUSA is an antimatter experiment at CERN's

Antiproton Decelerator (AD) and ELENA facility:

Antiprotonic helium atoms with laser spectroscopy to test the symmetry between matter and antimatter (CPT) by a precise determination of the antiproton-to-electron mass ratio.

The antihydrogen ground-state hyperfine structure to test CPT.

Atomic and nuclear collision cross sections of antiprotons at low (<100 keV) energies.
