IRFU's Double Chooz group has just published some surprising results regarding the flux of antineutrinos generated by uranium and plutonium fission products in nuclear power reactors. A more precise estimate of this flux has revealed a +3% shift with respect to the predictions considered as the benchmark for the past 25 years. The re-analysis of the most important past reactor neutrino experimental results, in the light of this new flux prediction, lead to the so called 'reactor antineutrino anomaly'.

The Double Chooz collaboration recently completed its neutrino detector which will see anti-neutrinos coming from the Chooz nuclear power plant in the French Ardennes. The experiment is now ready to take data in order to measure fundamental neutrino properties with important consequences for particle and astro-particle physics.             contacts:       Thierry LASSERRE Christian VEYSSIERE

Thierry Lasserre, a physicist at IRFU, has received the Bronze medal in the CNRS awards for 2009
On April 14, Thierry Lasserre received the CNRS bronze medal from the new director of the In2p3, Jacques Martino. Since 1954, CNRS has awarded three medals each year to renowned researchers or promising young scientists. This Bronze Medal rewards a researcher's first work, which marks that person as a promising specialist in his or her field. The work of Thierry Lasserre concerned the most abundant massive particle in the universe: the neutrino.

A company from the Vosges Department in France, NEOTEC, received the 2009 "Outstanding Implementations" award, at the International MIDEST Exhibition attended by the Industry Minister, Christian Estrosi, for their production of very special chambers. This equipment forms part of an important component of the Double-Chooz experiment which, before the end of the year, will measure neutrinos emitted by the reactor at the Chooz nuclear power station in the Ardennes.

The second phase of the Double Chooz international experiment officially began on Wednesday 20 May. The Declaration of Intent signed by the four partners (CEA, CNRS, EDF, Champagne-Ardenne Region) is the first step in the plan to build a second detector devoted to neutrino research next to the Chooz nuclear power plant. Prior to signing the DOI, the participants visited the site of the first detector, currently under construction.
