Interference of several gravitational quantum states of antihydrogen in GBAR experiment / Nesvizhevsky, V V (Laue-Langevin Inst.) ; Voronin, A Yu (Lebedev Inst.) ; Crépin, P P (Paris, Lab. Kastler Brossel) ; Reynaud, S (Paris, Lab. Kastler Brossel)
This analysis is based on a close analogy between two seemingly different experiments: on the gravitational properties of antihydrogen atoms in GBAR and on the neutron whispering gallery. They are described with high accuracy by the similar formalism. [...]

A pulsed high-voltage decelerator system to deliver low-energy antiprotons / Husson, A (IJCLab, Orsay) ; Kim, B H (Seoul Natl. U., Dept. Phys. Astron.) ; Welker, A (CERN) ; Charlton, M (Swansea U.) ; Choi, J J (Seoul Natl. U., Dept. Phys. Astron.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (IRFU, Saclay) ; Crépin, P -P (Paris, Lab. Kastler Brossel) ; Crivelli, P (Zurich, ETH-CSCS/SCSC) et al.
The GBAR (Gravitational Behavior of Antihydrogen at Rest) experiment at CERN requires efficient deceleration of 100 keV antiprotons provided by the new ELENA synchrotron ring to synthesize antihydrogen. This is accomplished using electrostatic deceleration optics and a drift tube that is designed to switch from -99 kV to ground when the antiproton bunch is inside – essentially a charged particle “elevator” – producing a 1 keV pulse.

Accumulation of Positrons from a LINAC Based Source / GBAR Collaboration
The GBAR experiment aims to measure the gravitational acceleration of antihydrogen H. It will use H + ions formed by the interaction of antiprotons with a dense positronium cloud, which will require about $10^{10}$ positrons to produce one H + [...]

Development of a PbWO$_4$ Detector for Single-Shot Positron Annihilation Lifetime Spectroscopy at the GBAR Experiment / Kim, B H (Seoul Natl. U.) ; Choi, J J (Seoul Natl. U.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (IRFU, Saclay) ; Crivelli, P (Zurich, ETH) ; Crépin, P-P (Paris, Lab. Kastler Brossel) ; Dalkarov, O (Lebedev Inst.) ; Debu, P (IRFU, Saclay) ; Dodd, L (Swansea U.) et al.
We have developed a PbWO$_{4}$ (PWO) detector with a large dynamic range to measure the intensity of a positron beam and the absolute density of the ortho-positronium ($\mathrm{o-Ps}$) cloud it creates. A simulation study shows that a setup based on such detectors may be used to determine the angular distribution of the emission and reflection of $\mathrm{o-Ps}$ to reduce part of the uncertainties of the measurement.

Positron production using a 9 MeV electron linac for the GBAR experiment / Charlton, M. (Swansea U.) ; Choi, J.J. (Seoul Natl. U., Dept. Phys. Astron.) ; Chung, M. (UNIST, Ulsan) ; Cladé, P. (Paris, Lab. Kastler Brossel) ; Comini, P. (IRFU, Saclay) ; Crépin, P.P. (Paris, Lab. Kastler Brossel) ; Crivelli, P. (Zurich, ETH) ; Dalkarov, O. (Lebedev Inst.) ; Debu, P. (IRFU, Saclay) ; Dodd, L. (Swansea U.) et al.
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses a low-energy electron linear accelerator (linac). The driver linac produces electrons of 9 MeV kinetic energy that create positrons from bremsstrahlung-induced pair production. [...]
