Abstract :
To explore a region of νμ-ντ oscillation, a large-scale emulsion-counter hybrid experiment will be carried out at CERN. Research and development of fiber trackers for the νμ-ντ oscillation experiment is in progress. The required position resolution is less than 100 μm. This requirement comes from a requirement in the emulsion scanning sequence. To satisfy this requirement, the diameter of the fiber must be smaller than 500 μm and fibers must be stacked into multilayer sheets. The authors have studied the basic performance of the fiber produced by Kuraray Co. Ltd. and tuned dopant densities of the fluorescent dye for this purpose. To construct a multilayer fiber tracker, they have developed a machine by using a large diameter drum. The status of the R&D is reported
