=== Type B (Mark) ===
==== Past week report ====
 * Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen.
 * Enzo and Mark did a new overview screen for the BS.
 * Enzo added DIO cards to the rack and connected them to the coil drivers.
 * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range.
 * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring. 
 * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime.


==== Plan for week of 12/25 ====
 * Power outage 12/25.
 * Mark, Enzo, Fabian vacation
 * Shoda-san, Kozu-kun, Hirata-san at Kamioka - Hirata-san from Tue, others TBD.

 * Install new jack receptacles (in SR3 area, second floor) on load gauge adapter (SR2 area, second floor). (Hirata-san)
 * Weigh IM (per Fabian's note in the paper log).
 * Remove L-brackets from bars on IM ring - send for cleaning/remachining.
 * Setup OL for checking pitch of SR.
 * Wipe/blow dust off SR2 frame.
 * Crane IM into frame.

==== Plan for week of 1/9 ====
 * Mark, Fabian, Enzo, Shoda-san at Kamioka Tue-Fri.
