Past week report
At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun):
We moved or covered stuff in the BS cleanbooth to prepare for the SR2 crane slot cutting and BS-> SR2 assembly frame move.
- We put the service port covers back on at the BF level of the BS tank.
- We used the PI jacks to center the bottom of the security structure around the RM.
- We debugged a mechanical issue where the #2 IP LVDT had too narrow a gap between the moving and fixed parts, so that there was interference with only a very small clockwise yaw of the IP. We fixed it by moving the bottom baseplate (taking advantage of the fact that it was held by screws in oversize holes for this purpose).
- We used the IP FRs to center the IP.
- We set the gains on the IP LVDT driver.
