| * Fabian took photos of the cleanroom in the ATC to help decide whether it is a good place to assemble PIs for Type A/B. * Hirata-san wiped one set each of wires for the BS and RM (addition sets pending). * Hirata-san washed remachined locking parts for the IM and screws for jacks. * Hirata-san liaised with Ikenoue-san of ATC to get winch parts designed for the new wire thicknesses. * Hirata-san worked on the Inventor 3D assembly of the SR2. * The scale for checking the masses of the IM parts was received. * Fabian and Hirata-san identified an issue with the lock screws between the IM and IRM. The screws were too tight in the holes and adjusting the size with a die caused large flakes of the black coating to come off. (These screws were ordered before the current screw policy was instituted.) Hirata-san will order better screws from Misumi and have additional machining done on them. * Fabian tracked down the calibration factors for the geophones and generated a calibrated plot. * Type B ongoing issues * OSEMs * Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test ongoing. * Lower breadboard stuff * Installation to be incorporated into the procedure document.

- Type B Past Week Summary
- Fabian, Mark and Liu-kun did BS installation at Kamioka:
- Connected the DIO card to the LPCD. (Simulink model changes will be needed to make use of it.)
- Took TF data from the TM-H1 coil output to the voltage and current monitors and found that the response was approximately flat, meaning that meaningful TFs can be taken of the RM/BS stage with no DIO.
- Used the 90° prism and the optical lever to set the pitch of the RM to match the dummy BS.
- Removed the RM trolley and added the bottom section of the security structure.
- Lifted the IM/RM/BS with the load gauge adapter and load gauge and measured its mass.
- Hirata-san:
- Mark checked lots of drawings by Hirata-san.
- Mark worked on schedule but only succeeded in completely garbling the Type B section of the VIS schedule on the server.
- Fabian, Mark and Liu-kun did BS installation at Kamioka:
- Longer term to-do list
- Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing.
