KLOE-2 at the e+e− DAφNE φ-factory is the main experiment of the INFN Frascati National Laboratories (LNF) and is the first high-energy experiment using the GEM technology with a cylindrical geometry, a novel idea that was developed at LNF exploiting the kapton properties to build a light and compact tracking system. Four concentric cylindrical triple-GEM detectors, for a total material budget below...
The KLOE-2 Inner Tracker, the first fully-cylindrical GEM detector ever built, is being commissioned at the Frascati Laboratory of INFN. KLOE-2 is the first experiment exploiting GEM technology with cylindrical geometry. Tracking performance of this novel detector are being studied using both cosmic-ray muon and Bhabha scattering events. Alignment and calibration procedures to reach design spatial...
We report on the design and the construction of a triple-GEM detector as the new Inner Tracker (IT) for the KLOE-2 experiment at the Frascati Φ-factory. The IT is composed of four tracking layers, each providing an independent two-dimensional space point. Each layer is a fully cylindrical triple-GEM detector. The front-end electronics is based on the GASTONE ASIC, specifically developed for this detector,...
We present the status of the R&D on the Cylindrical-GEM (CGEM) detector as Inner Tracker for the upgrade of the KLOE experiment at the DA??NE ??-Factory. The R&D activity spreads on different lines: construction and complete characterization of the full size CGEM prototype, equipped with 650??m pitch 1-D longitudinal strips; characterization of the single-mask GEM technology for the realization...
