Contributed Talk

The status of the R&D on the Cylindrical-GEM (CGEM) detector foreseen as Inner Tracker for KLOE-2, the upgrade of the KLOE experiment at the DAFNE phi-factory, will be presented. The R&D includes several activities: i) the construction and complete characterization of the full-size CGEM prototype, equipped with 650 micrometer pitch 1-D longitudinal strips; ii) the study of the 2-D readout...

Contributed Talk

Cryogenic avalanche detectors combine dense noble gas media at cryogenic temperatures with electron avalanche multipliers, namely with Gas Electron Multipliers (GEMs) or thick GEMs (THGEMs). Such detectors are relevant in the field of rare-event experiments, in particular in those of coherent neutrino-nucleus scattering, dark matter search and solar neutrino detection, and in the medical...

64. Triple-GEM detectors for electron, proton and neutron beam diagnostics

Dr Paolo Valente (Istituto Nazionale di Fisica Nucleare Sezione di Roma 1)

Contributed Talk

Different detectors based on triple GEM technology realized in Frascati during the last years, will be presented.They have been used for the luminosity measurements at Dafne Phi Factory, for the beam position at BTF (Frascati) and at CERN H8 area, and for the high intensity neutron fluxes measurements at FNG and Frascati Tokamak Upgrade.We report on the design, construction and test of a GEM...

232. A UV sensitive integrated Micromegas with Timepix readout

Mr Joost Melai (MESA+ institute, University of Twente)

Contributed Talk

We present an imaging system consisting of a Timepix charge sensitive readout with an integrated Micromegas detector. The Al grid is supported by SU-8 pillars, this structure is post-processed directly onto the Timepix chip. The detector is made UV sensitive by evaporating a 200 nm thick reflective CsI photocathode onto the Al grid. With this technology we can create a monolithic imaging...
