Abstract :
A large scale scintillating fiber tracker using visible light photon counter (VLPC) readout was built as a prototype for the upgraded DØ central tracker. This prototype has been under test at Fermilab for six months using cosmic rays. A description of the components of the tracker including the photodetector, fibers, lightguides, ribbons, and DAQ is given. Preliminary results indicate a mean detected yield of about 10 photoelectrons per fiber, position resolution of 140 μm for a fiber doublet, and a doublet efficiency greater than 99%
