DA$\Phi$NE $e^{-}e^{+}$ collider of LNF-INFN produces $\varphi$ mesons, which decay into $K^{+}K^{-}$ pairs. Low energy monochromatic negatively charged kaons are stopped in a cryogenic deuterium gaseous target. The SIDDHARTA-2 experiment aims to explore $n^{-}K^{-}$ strong interaction for exotic atoms, performing spectroscopic measurements of the kaonic deuterium when they de-excite to $1s$ emitting X rays of about 8 keV. The X rays will be measured by SDDs, which are ideal devices for performing low energy X-ray spectroscopy, thanks to their good timing and energy resolutions. SDDs characterizations regarding stability, energy resolution and timing, will be presented.
