CaLIPSO

CaLIPSO

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. The decay of the tracer emits a positron which annihilate with an electron. As a result of the annihilation, two photons with energy 511 keV are emitted back-to-back and registered by the dedicated detectors. The line-of-response connects the two points ...

Objectives The scientific exploitation of the LHC (Large Hadron Collider), planned to start operation in 2008 will be the higher priority in high energy physics for the next coming years. In the following step new large instruments will be required to reach a fine characterization of LHC discoveries, and analyse new phenomena around the TeV scale. The energy required (probably a few TeV), will be precised by the first results of the LHC, i.e. about 2010. Two electron-positron collider projects are ...

Fission studies with the FALSTAFF fission fragment spectrometer

Fission studies with the FALSTAFF fission fragment spectrometer

This experiment aims to provide accurate data on actinide neutron-induced fission fragment characteristics (mass distributions, kinetic energy) and neutron multiplicities in the energy range between 500 keV and 20 MeV. Those data are of particular interest for the nuclear community in view of the development of the fast reactor technology. For thermal neutron energies, a lot of fission reaction data are available. Some of them are still partial or suffer from insufficient accuracy. In the fast neutron energy domain, ...

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. In 2007, The heaviest elements which has been named is the Darmstadtium, with 111 protons. Z=112 has also been claimed, as well as Z=113 from a japanese team.

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. A first test will be to verify the sign of the gravitational ...

Hadron Form Factors (Facteurs de Forme des Hadrons)

Hadron Form Factors (Facteurs de Forme des Hadrons)

Hadron electromagnetic form factors parametrize the internal structure of hadrons, the dynamical distribution of magnetization and charge created by the inner constituents.  They are considered fundamental quantities as they are a privileged background for interplay between theory and experiment. Elastic form factors are accessed experimentally through the measurement of differential cross section and polarization observables in elementary reactions such as electron-proton elastic scattering and the ...

LUMINEU

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. If observed, this process will prove that the lepton number conservation law can be violated and that we need to extend the Standard Model. The LUMINEU experiment (Luminescent Underground Molybdenum Investigation for NEUtrino mass and nature – French ANR project) is focused on the investigation of the molybdenum ...
