Removed extra beamsplitter in MC WFS path |
|
|
As discussed in the meeting, I removed the extra beam splitter that dumps most of the beam going towards WFS photodiodes. This beam splitter needs to be placed back in position before increasing the input power to IMC at nominal level. This is to get sufficient light on the WFS photodiodes so that we can keep IMC locked for more than 3 days. Currently IMC is unlocked and misaligned. I have marked the position of this beam splitter on the table, so putting it back in should be easy. Right now, I'm trying to align the mode cleaner back and start the WFS loops once we get it locked. |
