Spatial resolution studies using point spread function extraction in optically read out Micromegas and GEM detectors
/ Cools, A. (IRFU, Saclay) ; Ferrer-Ribas, E. (IRFU, Saclay) ; Papaevangelou, T. (IRFU, Saclay) ; Pollacco, E.C. (IRFU, Saclay) ; Lisowska, M. (CERN) ; Brunbauer, F.M. (CERN) ; Oliveri, E. (CERN) ; Iguaz, F.J. (SOLEIL, Saint-Aubin)
Optically read out gaseous detectors are used in track reconstruction and imaging applications requiring high granularity images. Among resolution-determining factors, the amplification stage plays a crucial role and optimisations of detector geometry are pursued to maximise spatial resolution. [...]

Recent developments have shown that coupling a Micromegas gaseous detector on a glass substrate with a transparent anode and a CMOS camera enables the optical readout of Micromegas detectors with a good spatial resolution, demonstrating that the glass Micromegas detector is well-suited for imaging. This feasibility test has been effectuated with low-energy X-ray photons also permitting energy resolved imaging. [...]
