Abstract :
The timing resolution of a VLPC/preamplifier system has been measured using a pulsed nitrogen laser light source. Several fast, low-noise, transimpedance amplifiers have been tested. To determine the timing resolution degradation due to the preamplifier circuits, a high intensity light source was employed to allow studies of signals from the VLPC with and without amplification. The test apparatus is presented, and a new setup which includes a radioactive source for use with a scintillating-fiber/VLPC is proposed
