The PICOSEC-Micromegas (PICOSEC-MM) detector is a novel gaseous detector designed for precise timing resolution in experimental measurements. It eliminates time jitter from charged particles in ionization gaps by using extreme UV Cherenkov light emitted in a crystal, detected by a Micromegas photodetector with an appropriate photocathode.

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 imaging with Micromegas detectors with optical readout
/ Cools, A (IRFU, Saclay) ; Aune, S (IRFU, Saclay) ; Brunbauer, F M (CERN) ; Benoit, T (IRFU, Saclay) ; Corsi, A (IRFU, Saclay) ; Ferrer-Ribas, E (IRFU, Saclay) ; Iguaz, F J (SOLEIL, Saint-Aubin) ; Mazoin, C (IRFU, Saclay) ; Oliveri, E (CERN) ; Papaevangelou, T (IRFU, Saclay) et al.
Optical readout of Micromegas gaseous detectors has been achieved by implementing a Micromegas detector on a glass substrate with a glass anode and a CMOS camera. Efficient X-ray radio-graphy has been demonstrated due to the integrated imaging approach inherent to optical readout. [...]

Photocathode characterisation for robust PICOSEC Micromegas precise-timing detectors
/ Lisowska, M. (CERN ; IRFU, Saclay) ; Aleksan, R. (IRFU, Saclay) ; Angelis, Y. (Aristotle U., Thessaloniki) ; Aune, S. (IRFU, Saclay) ; Bortfeldt, J. (Munich U.) ; Brunbauer, F. (CERN) ; Brunoldi, M. (Pavia U. ; INFN, Pavia) ; Chatzianagnostou, E. (Aristotle U., Thessaloniki) ; Datta, J. (SUNY, Stony Brook) ; Dehmelt, K. (Jefferson Lab) et al.
The PICOSEC Micromegas detector is a~precise-timing gaseous detector based on a~Cherenkov radiator coupled with a~semi-transparent photocathode and a~Micromegas amplifying structure, targeting a~time resolution of tens of picoseconds for minimum ionising particles. Initial single-pad prototypes have demonstrated a~time resolution below 25 ps, prompting ongoing developments to adapt the concept for High Energy Physics applications, where sub-nanosecond precision is essential for event separation, improved track reconstruction and particle identification.

Bruno Kessler, Trento) ; Angelis, I (Aristotle U., Thessaloniki) ; Bomben, L (INFN, Milan Bicocca ; Milan Bicocca U.) ; Bonesini, M (INFN, Milan Bicocca ; Milan Bicocca U.) ; Branca, A (INFN, Milan Bicocca ; Milan Bicocca U.) ; Brizzolari, C (INFN, Milan Bicocca ; Milan Bicocca U.) ; Brunetti, G (INFN, Milan Bicocca ; Milan Bicocca U.) ; Calviani, M (CERN) ; Capelli, S (INFN, Milan Bicocca ; Milan Bicocca U.) et al.
Monitored neutrino beams are a novel technology designed to provide measurements of the neutrino cross sections at GeV scale with a total uncertainty of O(1%), thus improving by one order of magnitude current experimental estimates. The ENUBET project is close to proving for the first time the feasibility of this concept and the Collaboration is preparing a proposal for a new neutrino beam at CERN based on the SPS accelerator and the ProtoDUNEs neutrino detectors that are already operative at the North Experimental Area.

The PICOSEC Micromegas (MM) detector is a precise timing gaseous detector based on a MM detector operating in a two-stage amplification mode and a Cherenkov radiator. Prototypes equipped with cesium iodide (CsI) photocathodes have shown promising time resolutions as precise as 24 picoseconds (ps) for Minimum Ionizing Particles. [...]

Monitored neutrino beams are facilities where beam diagnostics enable the counting and identification of charged leptons in the decay tunnel of a narrow band beam. These facilities can monitor neutrino production at the single particle level (flux precision %) and provide information about the neutrino energy at the 10% level. [...]
