Line 6: Line 6:
  * Mark and Hirata-san at Mitaka
   * Gathered parts for cable making.
  * Mark and Hirata-san at Kamioka:
   * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
   * Installed two more LPCDs and the stepper motor driver in the PR2 rack.
   * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
   * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
   * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
   * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
   * Added extension to the IM pico cable for the BF yaw pico.
   * Made LVDT adapter cable.
  * Mark worked on schedule.
  * Mark and Hirata-san worked at Kamioka, with valuable help from Enzo (on loan from Type Bp team).
   * We got all the adapter cables for the BF made (Hirata-san did some work on Monday at Mitaka).
   * We installed the extension for the BF yaw pico on the IM pico adapter cable.
   * We got all the in-vacuum and in-air cabling for the IM OSEMs done.
   * We tried to install the stepper and LVDT adapter cables but realized we didn't have enough information on which wires was which. (We later tracked this info down but did not have time to do anything with it - we would have needed to do the rest of the in-vacuum and in-air cabling and set up the stepper motor and LVDT drivers, so we concentrated on the OSEMs.)
   * We plugged in the IM OSEMs, set gains and offsets, and did a noise test (analysis and klog pending).
   * We mounted the OSEMs on the IRM and routed the cabling neatly.
   * We released the suspension.
   * We adjusted the OSEM mounting plates to center the OSEMs on the flags.
   * We adjusted the OSEMs in/out to midrange.
   * The suspension is now ready for OSEM-OSEM TFs!
