Added autoalignment PZTs to ETMX green WFS
Daniel, Keita, Elli
This morning we worked on the ALS at Ex:
-We added autoalignment PZTs to the green WFS path. Mirrors ALS-M16 and ALS-M19 were taken out and and relaced with PZT mirrors. After adding the PZTs we realigned the green beam back onto the WFS.
-We removed two mirrors blocking the beam path upstream of ALS-M19. The mirrors weren't on the table layout and didn't appear to be doing anything.
-Swapped feedthorugh panels D1100434 on ISCTEX with replacement panels. The original panels had the wrong size screw spacing.
Two IR HR removed
There were two IR HR mirrors on the table that were not necessary any more, so I removed them and brought them back to the SQZ area cabinet.
Bug on the ISCTEX
Look what we've found there. I think the moth was attracted by the laser or maybe an LED inside, managed to crawl in from an opening under the white tape that covers a hole on the feedthrough panel, but couldn't find his/her way out and died.
I also found the same kind of moth in a bag of clean wipes. The entire bag went into the trash bin.
