We have carried out a pilot data taking of the J-PARC E05 experiment to search for the bound state peaks of 12Ξ Be in the 12C(K-,K+)X reaction at 1.8 GeV/c. The measurement was performed at the K1.8 beam line of the J-PARC hadron experimental hall with a typical K- beam intensity of 6×105 every six seconds. So far the best energy resolution of about 6 MeVFWHM was achieved with the existing SKS spectrometer. With a reasonable statistics, we have succeeded to observe peak structures in the bound region, which seems to suggest that the potential depth of Ξ would be deeper than 14 MeV estimated in the previous measurements.
