Development of a buffer gas trap for the confinement of positrons and study of positronium production in the GBAR experiment
The GBAR experiment relies on the production of antihydrogen positive ions to achieve its goal of measuring the gravitational acceleration of antimatter at rest. The ANTION project, included in the
A new path to measure antimatter free fall
We propose an experiment to measure the free fall acceleration of neutral antihydrogen atoms. The originality of this path is to first produce the H + ion. This ion can be cooled down to μK
Positron accumulation and manipulation for antihydrogen synthesis
Our group ASACUSA-MUSASHI has established an efficient way for accumulating antiprotons in the cusp trap, a combination of an anti-Helmholz superconducting coil and a multi-ring electrode trap. The
Investigation of buffer gas trapping of positrons
A study of positron capture in a two-(pressure) stage buffer gas accumulation apparatus is presented for a variety of species, including some molecules which are known to be either efficient for
Accumulator for the production of intense positron pulses
An intense pulsed positron source has been developed using a buffer gas trap to accumulate large numbers of positrons and create a dense plasma, which may then be bunched and spatially focused. Areal
Accumulation of LINAC based low energy positrons in a buffer gas trap
A buffer gas trap is applied successfully to accumulate more than 105 low energy positrons created with the electron linear accelerator at AIST, which can provide 40 MeV electron bunches at 40 Hz
