Abstract :
We have undertaken a research program to develop Scintillating Fiber charged particle Tracking (SFT) detector for the DO upgrade experiment at FNAL. We have developed a construction method utilizing scintillating fibers first accurately formed into ribbons, then precisely locating these ribbons on the inside and outside of a lightweight cylindrical base. A Coordinate Measuring Machine (CMM) is used to control each step of the ribbon mounting procedure. Ribbons 2 m long, containing 255 fibers each have been placed on composite structures with accuracy ~20 μm. The technique for producing highly accurate fiber ribbons and the method of precision placement of ribbons are presented. The spatial calibration of a charged particle tracker using the CMM measurements are discussed
