Control of plasmas for production of ultraslow antiproton beams
/ Kuroda, N ; Torii, H A ; Shibata, M ; Nagata, Y ; Barna, D ; Horváth, D ; Hori, M (CERN) ; Eades, John ; Mohri, A ; Komaki, K et al.
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. [...]

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. [...]

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. [...]

Res. of the Hungarian Acad. Sci., Debrecen, Hungary) ; Mohri, A (RIKEN, Saitama, Japan) ; Torii, H A (Inst. Phys., Univ. Tokyo, Japan) et al.
We have used a radio frequency quadrupole decelerator to decelerate antiprotons emerging from the CERN Antiproton Decelerator from MeV- to keV-scale energy, and collected five decelerated pulses in a multiring trap. Some 5*10/sup 6/ antiprotons were stacked in this way. [...]
