[Volker / Kiwamu]
This morning I went in the PSL room with an escort of Volker to replace a PD in one of the ALS paths. The PD (PDA100A) that had been in the ALS refcav transmission path [1] was replaced with a Thorlabs SM1PD1A as designed. The output DC current from the new PD was about 0.36 mA when the laser light is on the PD. Note that I used a standard Fluke digital multi-meter for reading out the photo current. So no DC bias was applied on the diode.
