We would like to thank the accelerator crew, the beam-channel group and other staff of the KEK proton synchrotron for their continuous support. We are very grateful to Nisseidenki Co. Ltd. for the construction of the SciFi-Blocks. This work was supported in part by a Grant-in-Aid for Scientific Research on the Priority Area “Strangeness Nuclear Physics” (No. 08239103) from the Ministry of Education, Science and Culture in Japan.

N2 - Scintillating-fiber-block detectors have been constructed using 0.5 mm square fibers for the KEK-PS E373 experiment, which searches for double-strangeness nuclei. The main aim of the detector is to measure the energies of protons and pions produced from decay of double- or single-hypernuclei using their ranges. It is also used to detect Λ hyperons or the H-dibaryon, and to make event selection. The performance of the detectors was studied with low-energy proton and pion beams as well as minimum-ionizing particles. The energy resolution determined by the range measurements was 0.86 MeV for 37 MeV π-'s and 1.4 MeV for 47 MeV protons. The excellent capability of π/p separation has been also demonstrated.
