ATHENA is an production press release by CERN .


THE EXPERIMENT

For Antihydrogen to be created, Antiprotons and Positrons must first be prepared. Once the antihydrogen is created, a high-resolution detector is needed to confirm that the antihydrogen was created, as well as to look at the spectrum of the antihydrogen in order to compare it to "normal" hydrogenhttp://athena-positrons.web.cern.ch/ATHENA-positrons/wwwathena/overview.html Summary of how the ATHENA experiment works.

The antiprotons are obtained from CERN's Antiproton Decelerator while the positrons are obtained from a Positron Accumulator . The antiparticles are then led into a recombination trap to create antihydrogen. The trap is surrounded by the ATHENA detector, which detects the annihilation of the antiprotons as well as the positrons.
