Description
The upgrade of the KLOE detector foresees the insertion of a new Inner Tracker
device around the interaction region of the DAFNE $\Phi$-factory, composed by
four tracking layers with diameters from 260 mm to 410 mm and an active lenght
of 700 mm.
They are realized as cylindrical triple-GEM detectors, a solution that
allows to keep the total material budget under 2\% of $X_0$ minimizing dead spaces.
The peculiar readout pattern with XV strips provides a spatial resolution of
about 200 $\mu$m on both views.
The readout system has been completely developed within the KLOE-2 collaboration.
It is composed by a digital readout front-end card based on the GASTONE ASIC and a
General Interface Board with a configurable FPGA architecture and Gigabit Ethernet.
We have built the two innermost layers that have been extensively tested
with 5.9 keV X-rays and cosmic rays.
We will report the construction procedure and the results of the
validation tests.
