  The time resolution for a charged particle detection is reported for a
typical scintillating fiber detector instrumented with Rockwell HISTE-IV
Visible Light Photon Counters. The resolution measurements are shown to agree
with a simple Monte Carlo model, and the model is used to make recomendations
for improved performance. In addition, the gain linearity of a sample of VLPC
devices was measured. The gain is shown to be linear for incident light
intensities which produce up to approximately 600 photoelectrons per event.
