The latest Micromesh Gas Amplification Structures (Micromegas) are achieving outstanding energy resolution for low energy photons, with values as low as 11% FWHM for the 5.9 keV line of $^{55}$Fe in...
A novel large-volume Spherical Detector with Proportional Amplification read-out (2008)
Giomataris, I., Irastorza, I., Savvidis, I., Andriamonje, S., Aune, S., Chapelier, M., ...
A new type of radiation detector based on a spherical geometry is presented. The detector consists of a large spherical gas volume with a central electrode forming a radial electric field. Charges...
Absolute measurement of the nitrogen fluorescence yield in air between 300 and 430 nm (2007)
Lefeuvre, G., Gorodetzky, P., Dolbeau, J., Patzak, T., Salin, P.
The nitrogen fluorescence induced in air is used to detect ultra-high energy cosmic rays and to measure their energy. The precise knowledge of the absolute fluorescence yield is the key quantity to...

The focal plane of the Simbol-X space mission (2006)
Dirks, B. P. F., Ferrando, P., Briel, U., Gevin, O., Kendziorra, E., Laurent, P., ...
In the paper, dealing with high-energy quasi-two-body or multiparticle production, the authors focus on what can be learned about exchanged naturality amplitudes from final polarization measurements...
Conditions on exchange mechanisms for polarization effects in inclusive reactions (2005)
In the framework of Mueller-Regge phenomenology the conditions under which one could expect to observe polarization effects in the fragmentation region for inclusive relations are investigated. On...
High-energy two-body photoproduction (2005)
Considers three aspects of two-body photoproduction reactions: vector meson production as a tool to investigate properties of diffractive reactions; the occurrence of a possible J=0 fixed pole in the...
