A new gamma-ray telescope using scintillation fiber together with an image intensifier is presented. The image intensifier we used has been improved in the sensitive range of the wavelength (beyond 300 nm) and the quantum efficiency (maximum 20%). The results of the beam test using the accelerator and the Monte Carlo simulation for the prototype telescope show that the device has the angular resolution of 0.5° at 900 MeV. On the basis of results of the prototype telescope, we propose a new SCIFI (SCIntillation FIber) telescope for future gamma-ray astronomy. The new telescope has achieved a large solid angle. With this merit, the new telescope can investigate very dark gamma-ray sources and monitor transient events such as gamma-ray burst. In addition, the cost of devices used in the telescope is not expensive so that an extension of the area of the telescope is easily realized in comparison with telescopes using silicon detector such as GLAST.
