Description

The KLOE-2 experiment represents the continuation of KLOE and acquired 5.5 fb$^{-1}$ data from November 2014 to March 2018 with the aim of collecting the largest sample of $\phi$ mesons at the DA$\Phi$NE $e^+e^-$ collider at the Frascati National Laboratory of INFN.
A new tracking device, the Inner Tracker, was installed at the interaction region of KLOE-2 and it was operated together with the Drift Chamber to improve track and vertex reconstruction capabilities of the new experimental apparatus.
The Inner Tracker is a four-layer cylindrical triple-GEM detector with each layer equipped with an X-V strips-pads stereo readout.
Although GEM detectors have been extensively used in high energy physics experiments, the IT, with its fully-cylindrical geometry, is a frontier detector and KLOE-2 is the first experiment which benefited of this novel detector technology operated at a collider.
The operation of the Inner Tracker will be presented,together with the results of the alignment and calibration and tracking-verexing performance of such a unique detector.
