Goals of the experiment
The R3B experiment is part of the FAIR project (Facility for Antiproton and Ion Research, http://www.gsi.de/fair) to be built at GSI (Darmstadt, Germany). The FAIR project gathers different physics around a common facility: exotic nuclei at low and high energy, hadronic physics with proton – antiproton collisions, relativistic heavy-ion collisions (a few 10 GeV per nucleon), plasma physics and atomic physics.

Gravitational Behaviour of Antihydrogen at Rest
Aims:
One of the fundamental questions of today’s physics concerns the action of gravity upon antimatter. No experimental direct measurement has ever been successfully performed with antimatter particles. CERN has thus launched a research program with the Antiproton Decelerator (AD) allowing to prepare a measurement of the effect of gravity on antihydrogen atoms.
The primary aim of this experiment is to determine how antimatter reacts to gravity.

Overview
Most of our current knowledge of the Universe comes from the observation of photons.
Photons have many advantages as cosmic information carriers: they are copiously produced, they are stable and electrically neutral, they are easy to detect over a wide energy range, and their spectrum carries detailed information about the chemical and physical properties of the source.

BOSS, eBOSS, DESI
Most of the content of the Universe, about 70%, is dominated by an energetic component that is neither matter nor radiation: dark energy. This mysterious component, first observed in 1998 with supernovae, revolutionized our vision of the evolution of the Universe and is one of the major discoveries of the end of the 20th century.
A characteristic scale of about 500 million light-years, acting as a "standard meter", is present in the distribution of matter on a cosmic scale.
Project context
The BTD project was developed in the framework of experiments aiming at the spectroscopy studies of radioactive nuclei using gamma-radiation and light particles in GANIL, mainly with SPIRAL and then SPIRAL2 beams. The purpose of these experiments is to study the structure of exotic nuclei in order to better understand the interactions that bind protons and neutrons and their reactions to different excitation modes (temperature, spin...).

As a result of the annihilation, two photons with energy 511 keV are emitted back-to-back and registered by the dedicated detectors.
