Cold Antihydrogen: Are We There? Cold antihydrogen offers the possibility to precisely compare the structure of antihydrogen and hydrogen atoms, using the well developed tools of laser spectroscopy with antihydrogen atoms cold enough to be trapped in the minimum of a magnetic field gradient. Progress made at CERN's new Antiproton Decelerator will be discussed, along with goals and aspirations, such as measuring the anti-Rydberg constant. ATRAP has observed and studied the interaction of low energy antiprotons and positrons for more than a year, and ATHENA hopes to soon make antiprotons and positrons to interact as well.
