GBAR Gravitational Behavior of Antihydrogen at Rest / Durpé, P (Saclay)
The GBAR experiment aims to test the Equivalence Principle with antimatter by measuring the time of flight of ultra-cold antihydrogen atoms H in free fall. Antihydrogen atoms at ¯ ∼20 µK are provided by sympathetic cooling of antihydrogen ions $\bar{H}^+$ with laser cooled $Be^+$ ions. [...]

Positron accumulation in the GBAR experiment / GBAR Collaboration
We present a description of the GBAR positron (e+) trapping apparatus, which consists of a three stage Buffer Gas Trap (BGT) followed by a High Field Penning Trap (HFT), and discuss its performance. The overall goal of the GBAR experiment is to measure the acceleration of the neutral antihydrogen (H) atom in the terrestrial gravitational field by neutralising a positive antihydrogen ion (H+), which has been cooled to a low temperature, and observing the subsequent H annihilation following free fall. [...]

Simulations of a cryogenic, buffer-gas filled Paul trap for low-emittance ion bunches / Lechner, S (CERN ; Vienna, Tech. U. ; McGill U.) ; Sels, S (CERN) ; Belosevic, I (TRIUMF) ; Buchinger, F (McGill U.) ; Fischer, P (Greifswald U.) ; Kanitz, C (Erlangen - Nuremberg U.) ; Lagaki, V (CERN ; Greifswald U.) ; Maier, F M (CERN ; Greifswald U.) ; Plattner, P (CERN ; Innsbruck U.) ; Schweikhard, L (Greifswald U.) et al.
Many experiments with pulsed ion beams benefit from or even require ion bunches with both small temporal width as well as small energy spread. To achieve optimal ion-beam preparation, a buffer-gas filled cryogenic Paul trap is being developed in the context of the Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS).
