Metrology for Biofuels

In order to anticipate the depletion of fossil resources (oil, gas, coal) and to reduce greenhouse gas emissions, current governments are encouraging the development of biofuels, produced from non-fossil organic materials. The European Directive 2009/28/EC thus promotes the use of biofuels and other renewable energies in transport.

Metrology for solid state lighting

LED lighting has a specific technology: - its optical performance and lifetime depend on the junction temperature of the LEDs and evolution over time is manifested by a very slow decline in the emitted flux  - LEDs have specific radiation spectra with a blue peak for the most common technology  - radiation is produced on small surfaces with no optics of concentration and therefore can be seen by the human eye with as very high intensity source points  - LEDs require specific electronics to be able to operate with electrical characteristics poorly taken into account in current measurement me

Angle Metrology (SIB58 Angles)

This project aims to meet current and emerging needs in the field of angle measurement (new, more accurate angle encoders, alignment of scientific equipment in particle accelerators, in situ calibrations with increasingly low uncertainties, etc.).

Metrology for high-impact greenhouse gases

The term "greenhouse gas" (GHG) includes various gases naturally present in the atmosphere (CO2, CH4, N2O, O3) or resulting from human activity (CO2, CH4, CF4, SF6,...) and which have in common to absorb solar radiation re-emitted by the Earth's surface, thus contributing to global warming.

Quantum engineered states for optical clocks and atomic sensors (QESOCAS)

The stability of atomic clocks operating in the optical domain is currently limited by two factors: the frequency noise of the laser used to probe the atomic system and the quantum projection noise, which intervenes when the state of this system is detected. This European QESOCAS project addresses these factors that limit uncertainties at the 10-18 level. These studies could have an impact on most clock applications and open the possibility of new applications.

Metrology for Smart Electrical Grids

The electrical grid is currently undergoing profound changes throughout the world. Indeed, the current supply networks, which are centralised and incorporate a large share of fossil fuel power plants, must migrate towards an increased integration of renewable energy sources (RES).
