The main aim of the SIDDHARTA-2 experiment at the DAΦNE collider in the LNF-INFN (Italy) is to perform the high precision measurement of the kaonic deuterium exotic atom, which is formed when a negatively charged kaon (K−) is captured in a highly atomic excited state, replacing an electron [1,2].
To achieve this goal, a large area Silicon Drift Detectors (SDDs) system has been developed by the SIDDHARTA-2 Collaboration [3]. The energy response of each detector should be calibrated and monitored to reduce the systematic error (to the level of 2-3 eV).
The poster will present a calibration method for the SIDDHARTA-2 setup [4], which should guarantee high precision spectroscopic performances of the system during the data taking.
