The ion-optical characteristics of the separator should meet the requirements of the antiproton beam, the parameters of which are given in Table 1. The magnetic bending power is 13 Tm; the transverse acceptance is 240 mm mrad; the momentum acceptance is 6 %. These parameters require magnets with large aperture, especially in the horizontal plane (up to 400 mm). The ion optics of the antiproton ...
Precision spectroscopy of antiprotonic atoms will be an important subject to be pursued at the new antiprotonic decelerator (AD) facility being completed at CERN. In particular, the study of antiprotonic helium atoms, peÿHe2 pHe, ®rst discovered at KEK and studied in detail at low-energy antiproton ring (LEAR), will continue to be one of the most important subjects at AD. Our recent high-reso...
The study of antiproton yield in $p$-$p$ and $p$-$d$ collisions is important for the astrophysical search dark matter consisting Weakly Interacting Massive Particles. Refinement production cross section, angular momentum spectra produced antiprotons a wide energy range could help to treat results obtained by AMS-02 PAMELA orbit spectrometers. In this paper we present detailed Monte Carlo possib...
Cooling and manipulation of a large number of antiprotons held in an electro-magnetic trap are key techniques for the synthesizing antihydrogen atoms and antiprotonic atoms [1]. We, MUSASHI sub-group in ASACUSA collaboration, achieved accumulation and cooling of antiprotons with at least 50 times higher efficiency than has been achieved by conventional methods [2]. Extracting these antiprotons ...
Fermilab operates the world’s most intense source of antiprotons. Recently various experiments have been proposed that can use those antiprotons either parasitically during Tevatron Collider running or after the Tevatron Collider finishes in about 2010. We discuss the physics goals and prospects of the proposed experiments.
