- 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.
