| ==== Report for week of 4/9 ==== * We packed away the SRM SF and BF. * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing. * Tanioka-kun built two IRMs (less OSEMs). * Enzo built an RM. * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.) * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM. * Eleonora and Izumi-san revisited the BS length to tilt coupling, which had degraded, and got it working again. |

Type B (Mark)
Report for week of 5/28
- Enzo tested the LVDT driver repaired by Tanaka-san - it was fine.
- Fujii-kun and Enzo finished assembling a batch of 4 geophones and took test data.
- Hirata-san modified some Promec masses (drilling out the threads on 2 of 4 holes) so we could use two layers of them inside the BF.
- Hirata-san installed maraging rod receptacles in the LBB damper rings, and in the bottom of PIs #3 and #1 (for the SF damper rings).
- After consulting with various people, Hirata-san installed the second half of the LBB top ring in the chamber, simply omitting the pillar and screw associated with the badly threaded hole.
- Hirata-san took delivery of the screws for the LBB blade units, made up 9 blade units and installed 6 of them on PI #3 and #1 (for SR3 and SR2).
- Hirata-san made up a set of PI cable clamps and installed them on PI #3 (for SR3).
- Hirata-san removed the prototype blades from PI #3 to get ready for testing the final blades.
- We located the #355 disk and #356 poles for the next level of the security structure up to the SF and installed the poles.
- We installed ballast mass in the BF. After some trial and error we settled on 16 Promec masses (7.1 kg) inside the BF and 5 D1808104-4 and 3 D1808104-5 masses (540 g) on the cap.
- Enzo did several rounds of TFs on the BF/... section of the suspension, and ins
