X-ray spectroscopy is an advantageous tool for investigation of the shift and width of the energy levels in kaonic atoms, evoked due to strong interaction between nucleus and kaon. In order to study the 2p level shift in kaonic 3He, the X-ray transition 3p→2d in liquid kaonic 3He will be measured with a precision of <2 eV in the E17 experiment at J-PARC. To reach this desired precision, a well designed setup, in-situ calibration and state-of-the-art semiconductor detectors will be used. The idea and the preparation status of the whole setup will be reported in this article.
