Proton-proton, antiproton-antiproton and proton-antiproton correlations

SPIE Proceedings, 2017
Properties of nuclear matter under extreme conditions can be studied through experiments with heavy-ion collisions at high energy. It is not possible to directly measure the sizes of particle-emitting sources, but it is possible to infer them with the use of femtoscopy. In order to determine the space-time properties of the sources, the femtoscopy uses

Deceleration and capture of the antiprotons

Hyperfine Interactions, 1989
The performances of proposed decelerators are compared using as figure of merit their efficiency to produce low energy antihydrogen, by means of catching the antiproton-bunch in a trap for successive cooling and recombination with positrons.

A single trapped antiproton and antiprotons for antihydrogen production

Hyperfine Interactions, 1993
During the last several years, our TRAP collaboration has pioneered techniques for slowing, trapping, cooling and indefinitely storing antiprotons to energies more than 1010 times lower than previously possible. The radio signal from a single trapped antiproton is now being used for precision measurements. Many cold antiprotons are “stacked” as another

Calculation of antiproton yields for the fermilab antiproton source

Nuclear Instruments and Methods in Physics Research, 1983
Abstract The available experimental data for antiproton production are described by an analytical formula, including target nucleus dependence. This formula, in conjunction with a Monte Carlo program that includes the effect of hadronic showers, is used to optimize the design of the Fermilab Antiproton Source.

Upper limits on dark matter annihilation cross sections from the first AMS-02 antiproton data

, 2015
The first measurement on the antiproton to proton ratio by the AMS-02 collaboration agrees with the expectation from conventional cosmic-ray secondaries in the kinetic energy range ∼ 20 −100 GeV, which can be turned into stringent upper limits on the ...

Antiproton Yield Optimization in the CERN Antiproton Accumulator

IEEE Transactions on Nuclear Science, 1983
The setting-up and optimization of antiprotons injected into the Antiproton Accumulator was initially based upon the measurement of circulating antiprotons by integration of their Schottky signals. This has now been supplemented by amplitude distribution measurements using an internal target. Also, the more readily detectable pions, muons and electrons,

Antiproton Production and Collection for the CERN Antiproton Accumulator

IEEE Transactions on Nuclear Science, 1983
Antiprotons are produced for the CERN Antiproton Accumulator (AA) by focusing 26 GeV/c protons onto a 3 mm diameter, 11 cm long copper wire. Negatively charged particles with momenta about 3.5 GeV/c are focused by a short focal length coaxial horn and transported to the AA by a normal quadrupole focusing channel.
