ISS array install/alignment update...I think we can mostly claim success

Rick S, Peter K, Matt H

 

More detailed report to come, but quickly... after a lot of long long days, I think we can mostly claim success that we think we have the ISS array aligned with ~50mV DC readouts from all 8 phtoodiodes (more detailed alog will hopefully have a description of the  temporary setup had to get this). We still dont see anything on the QPD though. Maybe as not enough power. Will have one last look tomorrow.

So just some tidy up work now to do on it before claim success (ie lid back on, put baffle back in place (which will need laser light for). I would say 30mins (lets say an hour to be safe :-)). Just to tired to finish it tonight.

 

Also before we attempt the LLO one I think we need a few modifications/solutions to make it a more efficient process. But we/I have learned alot from this one.
