At Kamioka (Mark, Fabian, Enzo, Perry, Hirata-san):
 * We set things up again after the floor coating work.
 * We moved the PI into the second floor of the cleanbooth:
  * We cleared a path for the forklift (moving the portable cleanroom, worktable, power cables, vacuum pumps and other obstacles).
  * We got Saito-sensei to move the PI to the +Y side of the cleanbooth.
  * We washed and cling-wrapped a pallet.
  * We got Miyoki-san to disconnect the cables and curtain blocking the crane slot (and reconnect them afterwards).
  * We added some temporary crossbars in the top of the assembly frame and stored the SF cap on them to get it out of the way.
  * We craned in the pallet and set it up to bridge three floor joists.
  * We craned in the PI using Saito-san's adapter.
   * We couldn't find the original screws for the three PI transport plates so we substituted some others - fortunately there was no galling.
   * We had to connect the adapter to the crane with a sling because the ring for the hook was slightly too small).
 * We did a lot of cabling work:
  * We routed all the BF cables over the BF cap, up through the cable clamp on the SF-BF rod and up to the SF. (We had to redo a few because the Type 3 cable was at the flange end instead of the Type 1.)
  * We connected up the SF LVDT and FR stepper.
  * We started on rebalancing the BF (which had been perturbed by the weight and tension of all the cables). We got it rather better, but it needs more work.
  * We made another batch of anti-feedthrough adapters.		  * 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.

 * Do TF from SF LVDT actuation.
 * Install temporary ballast mass in SF.
 * Lift SF/BF/... section and check total weight and SF balance.
 * Continue swap of PI LVDT connectors (female->male)
 * Start preparing LBB spring units.
 * Install pico drivers in rack, create MEDM interface (with Miyo-kun), and undo temporary connection of picos to old controller and joystick.
Week of 4/17:
 * Crane in PI.
 * Connect SF/BF... section.
 * Temporarily remove PI and adjust SF ballast if necessary.
