  5. IN2P3 laboratories in France 5

  6. IN2P3 Missions (placed inside) CNRS • Coordinate research for Particle and Nuclear Physics for the academic world. Coordination with CEA. • Coordinate 20 laboratories in network for the construction and operation of 40 large projects • Pluri-annual programming with annual arbitration • National operator for University/CNRS mixed laboratories responding to international large projects (in coordination with the CEA)

  7. Scientific axis of IN2P3

  8. Challenges • Ultimate components of matter and their interactions : • PARTICLE PHYSICS: • Quantum structure of the vacuum, origin of mass, • Higgs boson • Unification of fondamental interactions • Matter and et antimattter (quarks vs antiquarks et neutrinos vs antineutrinos)

  9. CHALLENGES • NUCLEAR AND HADRON PHYSICS • Proton and nucleus at extreme states, • emergence of complexity : • Structure of proton in quarks and gluons • Plasma of quarks and gluons • Exotic nuclei, nuclear structure, nuclear astrophysics

  10. CHALLENGES • ASTROPARTICLE PHYSICS • The Universe as a laboratory: • New messengers, high energy photons, neutrinos, cosmic rays and gravitatonal waves… • The origin and physics of cosmic rays of the highest energy • Dark matter and energy, the confrontation of the first moments of the Universe with the theories of the infinitely small

  11. PRIORITIES • SOCIETY GOALS • NUCLEAR ENERGY. Participate fully in the fundamental research on nuclear energy (PACEN) hybrid reactors, • Th cycle ... • INFORMATION TECHNOLOGY. Disseminate to other disciplines the knowhow acquired with the GRID through LCG and EGEE • ACCELERATOR AND DETECTORS. Increase the R&D on accelerators and instrumentation, amplify the technology trasfer (hadrontherapt, biomedical imaging, clinical help, environmental sensors and tracers)

  18. French Involvement in JLab Science(since ~1993) • French Scientists are spokespersons on 18 Approved Experiments at JLab • 139 Ph.D French Scientists are or have been active on at least one experiment proposal at Jefferson Lab • 21 Students or Former Students, either of French citizenship or from a French Institution, are working at the Laboratory • 21 French postdocs have worked or are working on Jefferson Lab Research • 28 French Students have completed PhD research based substantially on work at Jefferson Laband 14 more have thesis projects in progress • ~4 French high school students and 10 master's students • 11 French students did their military service as "cooperant scientifique" at Jefferson Lab. • 4 (annual) best JLab PhD thesis prizes (Courtesy of L. Cardman)

  20. Projects CLAS12

  21. Neutron Detection @ CLAS12 … European initiative towards the central detector … 5 T @ target IPN Orsay / LPSC Grenoble / INFN / Glasgow ToF scintillators • The neutron detection capability in the central region of CLAS12 is studied. Vertex detector Neutron detector • Neutron detection at laboratory angles larger than 40° • An efficient and fully exclusive study of the neutron-DVCS process • Via the D(e,e’n)p reaction • Valence kinematics: x-Bjorken > 0.2 Bench Test @ Orsay • The main question is the reliability and feasability of ToF measurements in the current configuration involving short flight paths, small energy deposit, and magnetic field.

  22. Polarized positrons @ JLab LPSC Grenoble / LPC Clermont Ferrand /JLab/ODU • The possibility of a high intensity polarized positron source is investigated. • The design is based on a low energy (5-10 MeV) highly polarized (100%) and intense (1-10 mA) electron beam: • In a radiator, longitudinnally polarized electrons create via Bremsstrahlung circularly polarized photons which transfer their polarization to positrons via pair-creation. • Preliminary simulations indicate that one may create a beam of up to 10 nA within the CEBAF admittance, with ~50% longitudinal polarization. • A test experiment is being designed for the CEBAF injector. • Validate the concept • Measure the angular, energy and polarization distributions of positrons.

  23. Upgrade of the DVCS calorimeter • 132  208 PbF2 elements • Upgrade of 1GHz digitizer (ARS) & Trigger • 4x increase in data rate • Luminosity ≥ 2•1037 Hz/cm2. Spectroe’ LiquidH2, D2 Hall A DVCS, 6 & 12 GeV. Technical Projects 2008-- HRSTrigger Digital Trigger Analog Ring Sampler, (ARS): VME 6U.16chan x 1GHz
