CLAS12

Deeply Virtual Compton Scattering experiment at Jefferson Lab Hall B , with CLAS12, large acceptance spectrometer. Goals: Theoretical concepts as Generalized Parton Distributions (GPD), enable to probe with a dramatic accuracy the nucleon structure, and access the quark confinement in hadrons.

R3B

Reaction studies with Relativistic Radioactive Beams

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).

AGATA (Advanced Gamma-ray Tracking Array) is a new generation high-resolution γ-ray spectrometer providing unprecedented Doppler-correction capabilities thanks to a combination of fine detector segmentation, efficient pulse-shape analysis algorithms, and implementation of an innovative γ-ray tracking concept.

BTD (Beam Tracking Detector)

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.

CHyMENE

A thin cryogenic target for the studies of exotic nuclei

The CHyMENE project (Cible d'Hydrogène Mince pour l'Etude des Noyaux Exotiques - a thin cryogenic target for the studies of exotic nuclei) is part of the instrumentation necessary for the exploitation of the low energy beams (~ 5 to 25 MeV/n), such as SPIRAL2 beams.

Fulis rotating Target

Objectives While the heaviest element on earth is 238-uranium (with traces of Pu and Np in natural nuclear reactors) whose lifetime is 5 billion years, the last 60 years have seen the synthesis of dozens of new elements in laboratory, with shorter lifetimes.

MINOS

Scientific Issues and Project Framework The MINOS project aims at performing the spectroscopy of very exotic nuclei produced by fragmentation at the radioactive ion beam facilities such as RIKEN or GSI / FAIR.

MUSETT

MUSETT: A segmented Si array for Recoil-Decay-Tagging studies at VAMOS

A new segmented silicon-array called MUSETT has been built for the study of heavy elements using the Recoil-Decay-Tagging technique. MUSETT is located at the focal plane of the VAMOS spectrometer at GANIL and is used in conjunction with a gamma-ray array at the target position.

MUST2-Reactions

Structure and spectroscopy via direct reactions.

Program: Nuclear matter in extreme states /Nuclear structure / exotic nuclei Objectives The goals of this experimental program is to study the structure of unstable short-lived very-neutron-rich or neutron-deficient nuclei.

S3: Super Separator Spectrometer

A spectrometer for the very high intensity stable beams of SPIRAL2

The future superconducting linear accelerator of Spiral2 will provide very high intensity of stable ions beams. They can be used to produce nuclei with very low cross sections, like superheavy elements or neutron deficient nuclei close to the limit of stability.

SIRIUS

Spectroscopy and Identification of Rare Isotopes Using S3

The high-intensity stable beams of the superconducting linear accelerator of the SPIRAL2 facility at GANIL coupled with the Super Separator Spectrometer (S3) and a high-performance focal-plane spectrometer will open new horizons for the research in the domains of rare nuclei and low cross-section phenomena at the limit of nuclear stability.
