Notes by Elton

1. Fiber Specifications
   • Fiber measurements (JLab and Regina)
     • JLAB (Carl)
     • (Regina) Kuraray fibers have arrived, but were waiting for SMA connectors for testing. These have been received, so fiber testing can proceed.
2. FCAL Update
   • Flash ADC time resolution tests with laser+PMT. Mihajlo reported that he is setting up a test in the lab to measure the extraction of timing from measurements with a flash. The current setup

includes a laser feeding a pmt and the original single-channel FLASH ADC from Paul Smith. Ultimately the goal is to understand the accuracy of timing for the glass in the Fcal.
