September 24, 2015 | Instituts Carnot celebrate a decade helping businesses innovate

10 ans carnot gekko listThe 34 members of the Instituts Carnot network celebrated ten years of innovation on Wednesday, September 23, 2015 at France’s National Library in Paris.

A technology showroom displaying demonstrator systems and products developed under R&D partnerships between businesses and members of the Instituts Carnot network was the focal point of this day-long event. And CEA LIST, a member of the Instituts Carnot network, took advantage of the gathering to present the Gekko portable non-destructive testing system developed under an R&D partnership with M2M.

Mr. Thierry Mandon, France’s Minister of State for Higher Education and Research, attached to the Minister of National Education, Higher Education and Research; and Louis Schweitzer, France’s Commissioner General for Investment, highlighted the values and results of the Instituts Carnot, an original and particularly effective initiative with some €1.3 million in new R&D contracts signed each day.

The Instituts Carnot have been leading the way in R&D partnerships to help businesses innovate for ten years: the network accounts for more than 55% of R&D outsourced by businesses to public-sector institutes in France and represents just 15% of France’s public R&D personnel.

September 2, 2015 | Direct dosimeter calibration for greater precision

CEA LIST laboratory LNHB (Laboratoire national Henri-Becquerel) now offers the first-ever medium-energy X-ray photon calibration method based on the absorbed dose to water, slashing measurement uncertainty threefold.

Current reference dosimetry measurements for medium-energy X-rays (80 kV to 300 kV) used in radiotherapy are generally stated as air kerma. The absorbed dose to water—the reference unit for radiotherapy—is extrapolated from the air kerma measurement, with typical uncertainty levels of 1.9% to 3.6%.

Water calorimeter developed by LNHB for calibration

LNHB designed and built a water calorimeter that reduced uncertainty to less than 0.8%. This primary instrument, which takes measurements at a depth of 2 cm as required by the IAEA protocol, can be used for the direct calibration of radiotherapy dosimeters..

The device was first used by the Institut de Cancérologie de l’Ouest René Gauducheau, in Nantes, France to calibrate an ionization chamber; a calibration certificate was granted for three medium-energy X-ray beams.

Because the calibration coefficient for this type of chamber varies by more than 10% for the energy range considered, depending on beam characteristics, having the LNE(France’s national measurement and testing lab)-LNHB primary reference measurements is crucial. This latest advance will position LNHB to offer calibration services to medical physicists across France.


20 juillet 2015 | KRONO-SAFE renforce son offre ASTERIOS avec une levée de fonds de 3,9 millions d’euros


KRONO-SAFE, start-up créée en 2001 et issue du List, institut de CEA Tech, vient d’annoncer une nouvelle levée de fonds d’un montant de 3,9 millions d’euros auprès d’investisseurs privés pour renforcer le déploiement, en industrie, de son offre ASTERIOS.
CM-CIC Innovation et Safran Corporate Ventures font désormais partie des investisseurs, aux côtés de CEA Investissement (via le fond Amorçage Technologique Investissement) et Scientipôle Capital.

Editeur logiciel pour l’embarqué temps-réel critique, KRONO-SAFE commercialise une technologie de rupture issue de travaux brevetés menés au sein de l’institut Carnot CEA LIST. Cette technologie permet de garantir sûreté et déterminisme des applications temps-réel critique tout en assurant une performance optimale, notamment sur des plateformes multi-cœurs.

En 2013, une première levée de fonds réalisée auprès de CEA Investissement et Scientipôle Capital, a permis de développer ASTERIOS, outil d’intégration automatique pour les applications temps réel, solution unique regroupant un RTOS et un IDE. Cette solution a été validée auprès d’industriels de premier plan dans les secteurs de l’aéronautique, de l’automobile, du ferroviaire et de l’automatisme industriel. Aujourd’hui, cette seconde levée de fonds d’un montant de 3,9 millions d’euros permet d’accueillir deux nouveaux investisseurs, CM-CIC Innovation et Safran Corporate Ventures, aux côtés des deux investisseurs historiques qui renouvellent ainsi leur confiance auprès de KRONO-SAFE. Cette nouvelle phase va permettre à la start-up d’accélérer son développement commercial à l’international, notamment à destination de l’Allemagne et des Etats-Unis.

July 2, 2015 | New calibrated fault solution for better cabling diagnostics

CEA LIST has developed some cutting-edge solutions for detecting and analyzing faults in electrical cable networks. CEA LIST innovations in cabling diagnostics are commercialized by startup WiN MS. CEA LIST continues to pursue advances to improve the solutions in the lab—work that requires generating intermittent faults, resistive and capacitive faults, and electric arc faults. The new solutions will help researchers “standardize” these faults.

Until now, researchers didn’t have a way to generate calibrated, reproducible faults. Instead, they had to resort to creating short circuits or breaking circuits manually. CEA LIST’s new intermittent fault generator—an electronic circuit board—will provide a solution.

Researchers can simply hook an electric cable up to the circuit board to generate the type of fault they are investigating:

  • Impedance faults (intermittent or not)
  • Intermittent faults with programmable durations, which, if needed, can be less than what current solutions can detect
  • Parallel electric arc faults that mirror what occurs in actual use when a cable’s insulation is worn or damaged
  • Serial electric arc faults, due to cable wear at the connector

Towards “standard” faults?

Now that it is possible to generate reproducible faults with calibrated duration and severity, it is also possible to come up with standard faults. A standard would be useful in evaluating the performance of cabling diagnostics systems as compared to a clearly-established reference.
