Type B (Mark)

Past week report

At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun):

We solved the problem with the OSEMs: cables had been plugged into the LED current monitor outputs, not the PD outputs.
We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power.
We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll.
We aligned the IM

Plan for week of 8/28

Kamioka: Mark (except Tue), Ohishi-san, Fabian (except Tue), Enzo (except Tue), Hirata-san, Yoshioka-kun (Fri), Kozu-kun (Thu, Fri).

Add BF cap; cable and test BF-1 and BF-2 picos.
Lift and weigh BF/IRM/IM/RM/BS; adjust ballast mass.
Crane in SF.
Suspend BF/IRM/IM/RM/BS.

Plan for week of 9/4

Install SF cap; route cables.
Lift and weigh SF/BF/IRM/IM/RM/BS.
Adjust SF ballast.

Vacation Info

-At Kamioka (Mark, Enzo, Hirata-san, Yoshioka-kun):
 * We lubricated the stuck screw at the top of the security structure with stuck and were able to remove it.
 * Enzo disconnected and removed or coiled many in-vac cables at the PI level to free it.
 * We craned the PI. There was a minor safety incident - see below.
 * Hirata-san set up the filter service area, and we moved in a BF intended for one of the SRs (BF#3). 
 * Fabian and Hirata-san worked out a method for characterizing a single spring, and Fabian finished characterizing the first one.
 * We did a big tidy-up and clean-up of the area, especially the corner where we intended to do the gluing.
 * We set up the BS gluing jigs and applied the glue. We will check the results on Monday.
