Synthesis of Cold Antihydrogen in a Cusp Trap / Enomoto, Y (Wako, RIKEN) ; Kuroda, N (Tokyo, U.) ; Michishio, K (Tokyo U. of Sci.) ; Kim, C H (Tokyo, U.) ; Higaki,H (ADSM, Hiroshima) ; Nagata, Y (Wako, RIKEN) ; Kanai, Y (Wako, RIKEN) ; Torii, H A (Tokyo, U.) ; Corradini, M (Brescia U. ; INFN, Brescia) ; Leali, M (Brescia U. ; INFN, Brescia) et al.
We report here the first successful synthesis of cold antihydrogen atoms employing a cusp trap, which consists of a superconducting anti-Helmholtz coil and a stack of multiple ring electrodes. This success opens a new path to make a stringent test of the CPT symmetry via high precision microwave spectroscopy of ground-state hyperfine transitions of antihydrogen atoms..

Atomic collision experiment using ultra-slow antiproton beams / Torii, Hiroyuki A (Tokyo U., Komaba) ; Kuroda, N (RIKEN (main)) ; Shibata, M (RIKEN (main)) ; Imao, H (RIKEN (main)) ; Nagata, Y (Tokyo U., Komaba ; RIKEN (main)) ; Barna, D (CERN) ; Hori, M (CERN) ; Kanai, Y (RIKEN (main)) ; Mohri, A (RIKEN (main)) ; Varentsov, V L (Khlopin Radium Inst.) et al. /ASACUSA
The development of techniques to decelerate, cool and confine antiprotons in vacuo with an electromagnetic trap has opened a new research field of atomic physics of 'cold' antiprotons, including synthesis of antihydrogen atoms. At the Antiproton Decelerator (AD) facility at CERN, we the MUSASHI group of ASACUSA collaboration have so far achieved efficient confinement of millions of antiprotons in a Multi-Ring electrode Trap (MRT) installed in a superconducting magnet of 2.5 T, by a sequential combination of the AD (down to 5.3 MeV), an RFQD (Radio-Frequency Quadrupole Decelerator; down to 50–120 keV) and the MRT.

Antiproton and Electron Plasma Behavior and its Control for Production of Ultraslow Antiproton Beams / Kuroda, N ; Torii, H A ; Shibata, M ; Nagata, Y ; Barna, D ; Hori, M (CERN) ; Mohri, A ; Komaki, K ; Yamazaki, Y
For the production of ultraslow antiproton beams, decelerated antiprotons were captured in an electro‐magnetic trap and cooled by collisions with preloaded electrons. This electron cooling feature was non‐destructively monitored by measurement of electrostatic oscillations of the electron plasma. [...]

Extraction of ultra-slow antiproton beams and their physics application / Torii, Hiroyuki A ; Kuroda, N ; Shibata, M ; Nagata, Y ; Barna, D ; Hori, M (CERN) ; Mohri, A ; Komaki, K ; Yamazaki, Y
The Trap group of ASACUSA collaboration has decelerated and confined millions of cooled antiprotons in an electromagnetic trap, 50 times more efficiently than conventional methods. They were then extracted out of the magnetic field of 2.5 T and transported at 10–500 eV. [...]

Production of ultra-slow antiproton beams / Torii, Hiroyuki A ; Kuroda, N ; Shibata, M ; Nagata, Y ; Barna, D ; Hori, M (CERN) ; Eades, John ; Mohri, A ; Komaki, K ; Yamazaki, Y
We have recently succeeded in decelerating and confining millions of antiprotons, 50 times more efficiently than conventional methods, in an electromagnetic trap. These antiprotons were cooled by preloaded electron plasma to an energy below an electronvolt. [...]

To produce ultraslow antiproton beams, decelerated antiprotons were captured in an electro‐magnetic trap and cooled by collisions with preloaded electrons. This electron cooling feature was nondestructively monitored by measurement of electrostatic oscillations of the confined electron plasma. [...]
