* Type B Past Week Summary * 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. |
