Today I collected the data for shot noise intercept current for MC REFL PD. I didn't get many data points at higher DC voltage of the photodiode, cause the incandescent bulbs get burnt at that level; two bulbs I have burnt today. I will process the data and report.

This work was done in-situ, so no optics on the AS table were moved. The PSL shutter was blocked since the IR beam was not necessary, and would scatter off the bulb Riju put in front of the PD. |
