Similar to South Path, I have inserted a beam splitter in the north PMC reflection path. This is a BS1-1064-90-1037-45UNP beamsplitter set such that about 10% light is transmitting. See optical layout for the path changes. I found that the modulation depth fro North PMC PDH was already low enough (0.246), so I did not reduce it. I have changed the DC transimpedance of North Cavity Reflection RFPD SN009 similar to the south side to 929.09 Ohms. This has given us ee-way to increase light intensity in the path with autolockers still working.
