Spectroscopic study of $$Xi$$-hypernuclei provides insights into the $$Xi$$-$$N$$ interaction and the $$Xi N to Lambda Lambda$$ coupling strength. A missing mass spectroscopy of the $$Xi$$-hypernuclei was performed via the $$^{12}$$C$$(K^-,K^+)$$ reaction at J-PARC K1.8 beam line in 2015. In this measurement, we have achieved the missing mass resolution 5.4 MeV (FWHM). It is important to achieve a better missing mass resolution. As the next step, we are constructing a new spectrometer S-2S (Strangeness -2 Spectrometer) for the $$K^+$$. In this condition, the total missing-mass resolution would be affected mainly due to the target energy loss straggling. To reduce energy loss straggling in the target, we are developing an active target composed of scintillating fibers. We will present status of developments of these detectors.
