Past week report
- Mark analyzed the QPD data from Friday 12/1 and derived matrices to diagonalize the QPD, and calibrate output in µrad. In the process an error in the IM OSEM diagonalization was discovered: the P and Y gains were low by a factor 2.
- Mark re-zeroed the QPD after noting the micrometer readings so we can do TFs over the weekend.
- We prepared for the SR2 gluing:
- We aligned the SR2 in the box with the wedge on the correct side.
- We checked that the remachined BS prism holders fit on the PR2 mirror box.
- We checked that with Tatsumi-san's support ring, the prisms would go on at the right height.
- We checked the new magnet jigs.
- We glued ferromagnetic disks in a large number of IM flag tips and flag bases, and in the SR magnet jigs.
- We also glued SR magnets in the magnet bases.
- Hirata-san worked on procurement of magnets, payload parts, and also got the delivery of the ferromagnetic disks expedited so we could have them this week.
