BS M2 magnets
[Betsy Travis Arnaud]
Today, since BSC2 chamber was accessible, we checked the polarity of the four magnets located on the second mass (M2) of the beamsplitter with the electronic polarity tester.
As we were expecting (see 7693), three of them were flipped (UL UR LR), so Betsy reversed them as in E1100108.
Also, we took the serial numbers of the 10 bosems. They are referenced in the updated chart in E1200343
Attached are some nice pictures of ITMX ETMX BeamSplitter and the baffles
