The Radboud University Nijmegen (RU) 

The Radboud University is one of the leading academic communities in the Netherlands. The research group is embedded in the Institute of Molecules and Materials with its excellent and unique spectroscopic facilities (NMR, High Field Magnet, Free Electron laser Facility, Scanning probe laboratory, Trace gas Facility), its strong interaction between physicists and chemists and between theoretical and experimental groups, and a large degree of collaboration at international level. The IMM maintains a running budget of about 20 M€ and has 50 scientific staff members, around 30 postdocs and 115 PhD students, and 50 supporting staff members.

Within IMM the Trace gas research group develops state-of-the-art laser spectroscopic methods for the detection of trace gasses, relevant for biological and medical sciences. Currently, Quantum Cascade Lasers and mid-IR Optical Parametric Oscillators are used for this. The latest solid-state laser and optical fiber technology is also exploited to extend the capabilities of existing OPOs and QCLs and matching detection methods to retrieve and computer-analyze trace gas concentration data within seconds. The laser-based analytical instruments operate in the 1.5-10 μm wavelength range with maximum coverage of the molecular fingerprint region and superior wavelength agility (tens of thousands of distinct wavelengths per second). The latter enables rapid and accurate examination of complex gas mixtures, such as human  breath. Recently, the group has started several research projects developing mid- and near-infrared Frequency Combs for fast Fourier Transform Spectrometry to be implemented for chemical analysis.

Main tasks in FLAIR

Radboud University is FLAIR project coordinator being responsible for WP1 (Project Management). 

Responsible for WP3 (Laboratorty Spectroscopy): Within WP3 the Radboud University will be responsible for the relevant spectroscopic data and laboratory validation on selected new species or on species for which spectroscopic data is not available, using existing trace gas detection systems and commercial supercontinuum lasers in combination with sensitive spectroscopic methods. RU will also establish a reference data base and a consolidated list of target species for the test and validation phase (WP6 - Validation and Demonstration).

Responsible for subtask in WP6: Validation experiments will be performed with developed prototype under laboratory condition, at the Trace Gas Research Group at RU's premises.
