  1. N4, Double beta network Second year… …and next Dominique Lalanne Prague, April 20th, 2006, IDEA-N4 meeting

  2. N4 – Table 2: Deliverables for year 2, March 2006

  3. First step of an ICR design study Letter of Intend for FP7 -------------------------------------------------------------------------------- ISOTOPE ENRICHMENT BY MEANS OF AN ICR MACHINE. Institutes involved LAL and IN2P3 (France) LNL and INFN (Italy) CEA (France) Kurchatov (Russia) University of Pavia and INFN, sezione di Pavia (Italy) University of Milano Bicocca and INFN, sezione di Milano Bicocca (Italy) Drafting Group P. Benetti S. Julien D. Lalanne E. Previtali Type of Project: Design Study for an ICR facility for FP7 program Project Outline

  4. Double beta Network : Milestones of year 2

  5. WG1 : coordination of double beta decay searches Co-ordinator : Christine Marquet, CENBG, IN2P3, France discussions to address common problems project SuperNEMO The final report on background issues is in progress

  6. WG2-A: Bank of pure isotopes Co-ordinator Ezio Previtali, INFN, Milano, Italy “first version of a database on existing isotopes”. strategy for a possible isotope production in Europe with an Ion Cyclotron Resonance (ICR) facility. study of the possibility with CEA to restart a laser separation of Neodymium 150.

  7. WG2-B:Negotiations with Russian labs, new isotope production. Co-ordinator : S. Jullian Production of enriched Selenium. Two teams in Kurchatov Institute are interested in enrichment. One is working with a team of ITEP-Moscow. Selenium is possibly produced in Kurchatov Possibility at ECP-Krasnoyarsk facility. A meeting has shown that is it reasonable to produce 100 kilogram within 3 years in a new production unit ready for use

  8. WG3 : theoretical developments Co-ordinators : A. Faessler, F. Simkovic, J. Suhonen Three workshops (Durham, Erice, Corfu) have been co-organized with an important contribution of ILIAS participants allowing the following results: An overall analysis of the possible sources of differences between the various calculations has been performed Also some possible universal features of the matrix elements related to the neutrinoless mode of double beta decay have been pointed out Still under discussion remain the best independent probes of the matrix elements related to the neutrinoless double beta decay.

  9. Double beta Network : Deliverables of year 3

  10. Highlights Production of new isotopes : 1 - MENPHIS, Laser facility at CEA, Pierrelatte, France Possibility of production of 100 kg of 150Nd and 10’s of 48Ca with the existing facility to be adapted for new productions Negotiation with CEA to be done 2 - ICR Facility, as studied previously Design study to be done. LOI in FP7

  11. 2000–2003 Program : Menphis facility Evaporator Dye laser chain Yag laser Copper vapor laser Design : 2001 Building : 2002 1st test : early 2003 1st full scale exp. : june 2003

  12. Laser Isotope Separation (LIS) for 150Nd 1- Technical feasibility proven by Kurchatov Institute with a production of 40 mg/h with an enrichment level of 60% for 150Nd 2- MENPHIS, CEA Facility at Pierrelatte, France This Facility has worked in 2003 for a production of 200 kg of 235U enriched at 2,5%. It is now stopped and in stand-by. Visit of this Facility by Serge Jullian and D.L. Dismantling in principle delayed by one year. Possible study of transformations needed of MENPHIS for a 150Nd production. A-priori there is no difficulties for such transformations. Then a proposal can be done to CEA for a production of 150Nd.
