Past week report

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.
