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. [...]

Neutron and beta imaging with Micromegas detectors with optical readout

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. [...]

PUMA, antiProton unstable matter annihilation
/ PUMA Collaboration
PUMA, antiProton Unstable Matter Annihilation, is a nuclear-physics experiment at CERN aiming at probing the surface properties of stable and rare isotopes by use of low-energy antiprotons. Low-energy antiprotons offer a very unique sensitivity to the neutron and proton densities at the annihilation site, i.e. [...]

Radiation imaging with glass Micromegas

Optically recording scintillation light emitted by MicroPattern Gaseous Detectors (MPGDs) with imaging sensors is a versatile and performant readout modality taking advantage of modern high granularity imaging sensors. To allow scintillation light readout of a detector based on MicroMesh Gaseous Structure (Micromegas) technology, we have integrated a Micromegas on a glass substrate with a transparent anode. [...]
