  * 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. Ikenoue-san provided updated designs for checking. (, )
  * 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.
  * Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa.
  * The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka.
  * Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa.
  * Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror.

   * Akutsu-san is working to get wide-mouth OSEMs ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1853|2 assembled]]; first 4 expected to be assembled and washed by 8/8)    * Akutsu-san is working to get wide-mouth OSEMs ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1853|2 assembled]]; another few were assembled and a batch of 7 were washed.
   * Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year).
Line 19: Line 16:
  * SR machining test ongoing.   * SR machining test NEARLY DONE. The part looks good and will be used but the ones for SR3 and SRM will be made from scratch.
Line 22: Line 19:
   * Breadboard springs (in manufacture, expected end of July)    * Breadboard springs - RECEIVED.
Line 27: Line 24:
  * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian).   * Pack/ship IM/RM/IRM to Kamioka (Hirata/Fabian) - from 8/1.
Line 29: Line 26:
  * Remove glue from dummy BS face (Fabian) - partly done.
  * Reglue flags and prisms (Tatsumi, Fabian)
  * Remove glue from dummy BS face (Fabian) - MOSTLY DONE.
  * Reglue flags and prisms (Tatsumi, Fabian) - from Friday 8/5.

  * Check SR RM machining test progress (Hirata)
