Performance of a large scale scintillating fiber tracker using VLPC readout
The authors report on results of a cosmic-ray test of a 3,072 channel scintillating fiber tracker using VLPC readout. This system is a prototype for the D0 detector tracking upgrade, and represents a configuration that is similar to that planned for the final detector. A detailed description of the cosmic ray test, including trigger, fiber configuration, lightguides, VLPC cassettes and cryogenics, calibration system, and DAQ is given. Tracking results with a muon momentum cutoff of 2.5 GeV/c include R-{phi} and R-Z resolution studies, light yield/mip, and efficiency measurements. Preliminary analysis gives a most probable value of 19.2 photoelectrons/mip per fiber doublet, an R-{phi} resolution of 163 microns (before corrections for fiber position survey), and an efficiency of nearly 100% after accounting for known dead channels in the system.
