Development of Silicon Strip Detector for the measurement of the Ξ‐atom X‐rays

We have developed the Silicon Strip Detector (SSD) for the experiment to measure X‐ray from Ξ‐atom. The feature of the SSD is to measure positions of particles and energy deposit. We have carried out the test experiment at J‐PARC K1.8 beam line. The three SSDs were installed in front of the target and we tested by using kaon beam. In this paper, the results of the test experiment is presented.
