To find the right impedance, we tried 1 MOhm, 1 kOhm, 500 Ohm, 250 Ohm, and 50 Ohm. We found that 500 Ohm gives the right size of signal (~1.00 V) and does not slow the rise time (e.g., when compared to 250 Ohm).

Body: 

Hall D IA system rise time was measured with a biased photodiode and a scope with 500 Ohm input impedance. The rise time is about 6 us. No more measurements are planned in the laser room as of now.

We will close this ATLis once we do a through analysis of the data.
