Today we scanned the bulk sample in z to find the sample center (at z=37.935mm)
Then we had to slightly move the power-meter to get the beam centered.
Finally, we could get R_bulk = 0.7414 with
AC_bulkref = 0.05762;
DC_bulkref = 4.615;
P_in = 23.0e-3;
ACDC = 0.01253;
P_t = 11.4e-3;
This is quite close to the previous value (0.78).
We used as a goal for this calibration 0.74 and stopped when we got this value...
We'll try little more tuning on Monday before starting the absorption measurement.
