| Research Abstract |
This project aims for a stringent CPT symmetry test employing a so-called CUSP trap scheme, where a spin-polarized slow antihydrogen beam can be extracted. With the extracted beam, a high precision microwave spectroscopy can be realized. In 2010, we have succeeded to synthesize a large number of antihydrogen atoms in the cusp trap, which was selected as the best research of the ten breakthroughs in 2010 by Physics World together with the trapping of antihydrogen atoms in a magnetic bottle, to which the principal investigator was also involved.
