ATLAS

Atlas is one of the general purpose detectors which started operation in 2008 at the the CERN proton collider, to study the Higgs boson. Goals: Unifying the elementary constituants of matter and their interactions.

ATLAS-Calorimeter

ATLAS-Muon Spectrometer

ATLAS-Toroid

CMS

CMS is the detector of one of the 2 multi-purpose experiments out of the 4 experiments located at the LHC at CERN near Geneva. CMS is installed at point 5 in Cessy.

Antares, a high energy neutrino telescope

The sky observed from the sea deeps

Overview Most of our current knowledge of the Universe comes from the observation of photons.

Antares, a high energy neutrino telescope

BABAR

Goal The main goal of the experiment was to perform a complete study of CP violation (CP is the symmetry linking particules and antiparticules) in the system of B mesons.

BAO

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.

CaLIPSO

Development of innovative detectors for Positron Emission Tomography

Positron emission tomography (PET) is a powerful nuclear imaging technique used widely nowadays in oncology, cardiology and neuropsychiatry. The PET technology consists in injecting the patient with a radioactive tracer, of interest to probe a biochemical process.

CTA (Cherenkov Telescope Array)

A new generation observatory to explore the high energy Universe. Une nouvelle génération d'observatoire pour explorer l'Univers à haute énergie.

D0

Presentation The D0 experiment was located at the proton-antiproton Tevatron collider at the Fermilab laboratory (Chicago, USA). There was two data taking periods: Run I from 1992 to 1996 with a center of mass energy of 1.

Detectors for linear collider

FELICE

FELICE (acronym for "Future Electron LInear Collider Experiment") is a group of physicists and engineers working for the physics and detectors at the ILC (International Linear Collider).

Double-Chooz

Contact: Thierry Lasserre (thierry.lasserre@cea.fr)

Scientific goals : Neutrinos are elementary particles produced abundantly in stars, in the Earth's atmosphere and in the cores of nuclear power plants. In 2006 CEA/IRFU and CNRS/IN2P3 have decided to officially launch the construction of the Double Chooz experiment.

Edelweiss

Objectives The goal of Edelweiss is to detect the dark matter of our Galaxy through its interactions in detectors operated in underground laboratory.

GBAR

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 had been successfully performed with antimatter particles in the 2010's.

HESS

Exploring the High Energy gamma ray sky

H.E.S.S. Exploring the High Energy gamma ray sky H.E.S.S stands for "High Energy Stereoscopic System".

LUMINEU

Neutrinoless double beta decay is a very rare nuclear transition, whose existence can provide essential information about neutrino properties like the hierarchy and the absolute mass scale.

QUYOS

a Quantum Solar Concentrator based on Rotating Photon Optical Fibers

Basic principle of a Solar Concentrator with Rotating Photons Optical Fibers Coming from fundamental research on solar neutrino, the Solar Quantum Concentrator( CSQ) is a future low-cost and high efficiency solution for photovoltaic solar energy.

SNLS : SuperNova Legacy Survey

SNLS aimed at detecting type Ia supernovae at high redshift for cosmological studies.

T2K

T2K (Tokai to Kamioka) is the world leading experiment dedicated to the study of neutrino oscillations over a long distance using µ-neutrino and µ-anti-neutrino beams. Neutrinos exist in three different types (called 'flavours'): νe, νμ and ντ.
