The construction of Antiproton Decelerator (AD) at CERN in Geneva was completed in the summer of 2000, and important new results, such as high precision laser spectroscopy of antiprotonic helium atoms and production of a large number of cold antihydrogen atoms were obtained. We discuss these results and future prospects with emphasis on why decelerating antiprotons to low energies can open up an interesting new physics.
