La nano/micro-électronique au LSM

Les neutrons et les rayonnements alpha de la radioactivité naturelle

sont la source d’erreurs dans les circuits de microélectronique

L’utilisation de matériaux « radioactifs »

peut entrainer des incidents industriels

majeurs

Le LSM est laboratoire de référence

pour la norme internationale JEDEC

en microélectronique


Monte-Carlo Simulation of Underground Experiments

  • Up to 20,000 h of cave characterization

  • -SER reevaluated to2079 FIT/MBit

  • Monte-Carlo simulation gives a contamination level by 238U impurities of 0.37 ppb

  • Very good agreement with wafer-level characterization (alpha emissivity) in the range [0.2-0.5] ppb


In 2006, the project of a safety galery along the Fréjus roadway tunnel

started to be realistic.

An unique opportunity

Deepest site in Europe (4800 mwe)

Known and « good » site (low convergence, dry, stiff rock)

Central location in Europe, easy access (plane, train car)

23 years experience in running such platform

Independent, convenient, safe, horizontal access

European Roadmap new projects

Integration of project to tunnel company planning and constraints

Performed pre study : moderate cost

ULISSE Project

Scientific Motivation : To be able to host the next generation of neutrino and

dark matter experiments

To develop the multi-disciplinarity of the laboratory

Improvement of detectors for low radioactivity measurements

Material selection

Use of radioactivity for environmental research :

Oceanography : Study of metals in the ocean, studies of water columns

Retro-observation : Human effect on the environment, study of Alpin lakes

Water quality : possibility to use sediments to know the state reference for the

Lake and the river as requested by EU

Studies of temperature water effect and fishing on the fish ressources

Climatology

Glaciology,....

Expertises : environmental survey

Wine datation

Salt origin,....


Virtuous cycle
Virtuous cycle roadway tunnel

  • Modeling the impact of radiation on living cells: Geant4 DNA

  • Validation: need for relevant observables to characterize biological systems

    • Cell survival rate

    • DNA single or double strain breaks

    • Molecular biology: genomic mutations, gene expression

  • Experimental protocol: compare observables after controlled radiation exposure

    • In normal lab conditions

    • After beam irradiation (γ, e-, p, α)

    • Need for a reference point at zero-radiation: Modane

Biologists, computer scientists

Physicists, chemists

Geant4 DNA


The reference point lsm
The reference point: LSM roadway tunnel

  • In normal lab conditions, cultures are exposed to 10 Millions cosmic rays per day per square meter

    • Low but significant radiation exposure

  • In Modane, down to 4 cosmic rays per day per square meter

  • Goal: study evolution of model organisms in radiation free environment

    • Bacteria life cycle

    • Mutation rate

    • Localization of gene mutations, gene expression

    • DNA breaks

LSM Extension roadway tunnel

LSM extension

There are several project of underground laboratories around the world

The extension of LSM will be one of the depth laboratory and will be attractive by

the quality of the site and the access.

Complementray offer with the other EU labs

It will allow to host some of the projects of the astroparticle roadmap in particular on

double beta decay and dark matter searches.

Developments of the multidisciplibnaire plateform

Possibility to welcome new sciences : biology, geosciences,....

Laboratory built for at leats 40 years, very high scientific potential

Open to international partners



Factor of merit 150 nd
Factor of merit roadway tunnel150Nd

Activity = A

A0 =  M02 x G0 (Z, Q) x < m>2

150Nd is the best for GO phase space


Status on 150Nd enrichment roadway tunnel

Neodynium project started in 2006 with a strong involvement and support from

S. Jullian, G. Wormser and S. Katsanevas by studying the possibility to use

MEMPHYS AVLIS facility

2008 : Collaboration 150Nd created between SuperNEMO and SNO+ collaboration

to study the possibilities to produce high quantities of 150Nd

MEMPHYS facility dismantled in 2008

2010 : possibility to study and built a dedicated industrial facility for 150Nd is

proposed by CEA


Le projet SuperNEMO – Le besoin roadway tunnel

  • Détecter la désintégration « double bêta sans émission de neutrino » pour déterminer la nature du neutrino

  • Isotopes retenus à ce jour :

    • 82Se :

      • approvisionnement possible à court terme

      • Moins favorable que 48Ca ou 150Nd (bruit, élément de matrice, …)

    • 150Nd ou 48Ca

      • Pas d’approvisionnement en grande quantité possible d’ici 2018

      • Probabilité plus élevée, meilleur rapport signal/bruit

  • Besoin estimé en Nd enrichi : 100 kg de Nd à 60% en 150Nd


Les technologies d’enrichissement du roadway tunnel150Nd

  • UCG

    • Russie : développement en discussion

  • Laser :

    • Russie : production au niveau du laboratoire

    • France :

      • Expérience MENPHIS : 200 kg of Uranium at 2003

      • Savoir-faire – Livre de procédé SILVA uranium

        => Proposition de réaliser une installation pour la

        production de Néodyme enrichi
