Abstract: (SISSA)
KLOE-2 at the DANE collider is the main experiment of the INFN Laboratori Nazionali di Frascati (LNF) and is the first high-energy experiment using GEM technology with a cylindrical geometry, a novel detector developed at LNF exploiting kapton properties. Four concentric cylindrical triple-GEM detectors compose the Inner Tracker, inserted around the interaction region and before the inner wall of the pre-existing KLOE Drift Chamber, to improve the resolution on decay vertices close to the interaction point and reconstructed from low-momentum charged secondaries.State-of-the-art solutions have been expressly developed or tuned for this project: single-mask GEM etching, now used also for several LHC experiments upgrades, multi-layer XV patterned readout circuit, PEEK spacer grid, GASTONE front-end board a custom 64-channel ASIC with digital output, and the Global Interface Board for data collection, with a configurable FPGA architecture and Gigabit Ethernet. Alignment and calibration of a cylindrical GEM detector was never done before and represented one of the experiment's challenging activities. The first set of alignment and calibration parameters obtained with cosmic-ray muon data has been used to validate the integrated tracking and vertexing using both Inner Tracker and Drift Chamber information, exploiting the Kalman filter technique. Results obtained with and samples will be reported.KLOE-2 is presently taking data with the aim of collecting more than 5 fb by March 2018.The success of the cylindrical GEM technology developed by the KLOE-2 collaboration paved the way to its usage in other high-energy physics experiments, among these is the BES III experiment at BEPC II.- activity report
