Research Abstract

This project aimed at performing a variety of interdisciplinary studies using antiprotons(p^^-) from Antiprotori Decelerator (AD) constructed at CERN (completed in the end of 1999 with one year delay with respect to the original plan and started service in 2000 (summer) and hence creating a new field of antimatter science.
In the first half of the research project term, we constructed infrastructures at AD and developed experimental apparatus, which include 1) Radio Frequency Quarupole antiproton Decelerator (RFQD), 2) Monoenergetic Ultra Slow Antiproton Source for High-precision Investigations (MUSASHI), 3) laser system for antiprotonic atom spectroscopy, 4) antiproton annihilation detector, 5) low temperature gas target, 6) data acquisition and analysis system, and 7) antihydrogen(H^^-) synthesis and detection system.
In the second half of the term, numerous development experiments were performed. The major achievements are 1) success in mass production of antihydrogen atoms, 2) high p … More recision determination of antiprotonic mass through high resolution laser spectroscopy of antiprotonic helium(p^^-He^+) atoms, 3) efficient deceleration of antiprotons using RFQD, 4) measurement of hyperfine structure of p^^-He^+ and p^^- magnetic moment by laser-microwave spectroscopy, 5) efficient trapping of p^^- and extraction of ultracold p^^-(〜 10eV) by MUSASHI, and 6) observation of tunneling in low temperature chemistry of p^^-He^+.
Among other things, mass production of antihydrogen atoms is a breakthrough toward forthcoming high precision H^^- spectroscopy aiming at CRT test and the success in extraction of ultracold p^^- by RFQD and MUSASHI is a key technique for low energy collision experiments.
In the theoretical investigation of antiprotonic atom, precision in quantum three-body calculation has been much improved and p^^- mass was determined with a high precision (〜10^<-8>) and a full quantum-mechanical treatment of antiprotonic atom formation was invented.
At the end of the term we organized the International Conference on Low Energy Antiproton Physics (LEAP'03) at Yokohama. Less
