Towards the first kaonic deuterium measurement with the SIDDHARTA-2 experiment

The SIDDHARTA-2 experiment is presently installed at the interaction point of the DA$\Phi$NE electron-positron collider of the National Laboratories of Frascati (LNF-INFN), in Italy, ready to perform the first measurement of the 2p $\to$ 1s x-ray transition in kaonic deuterium. This measurement, together with that of the kaonic hydrogen 2p $\to$ 1s x-ray transition, performed by the SIDDHARTA experiment in 2009, will allow the determination of antikaon-nucleon isospin-dependent scattering lengths. This paper presents a description of the SIDDHARTA-2 setup, which is getting ready for the kaonic deuterium measurement.
