| ==== Past week report ==== At Kamioka (Mark, Enzo, Yoshioka-kun): * We experimented with rearranging the arc weights to accommodate the magic wands and came up with a suitable scheme. * We used spare arc weights as extra ballast on the LBB to get it to float, and measured the height for a known load. * We put the blocks back under the LBB and unhooked it. * We moved the suspension from the tank back to the assembly frame. * We craned the LBB rings down onto the LBB but did not remove them yet. (This however is the last crane work in the tank until reinstallation, so the lid does not have to come off again and the pallet can be used for the PI.) * We put the crossbars back in the assembly frame underneath the SF and BF (and corrected an error in the height of the BF ones). * We checked the centering of the security frame in the assembly frame and disconnected it from the PI. One M12x35 screw galled after a few turns and will need attention. * Enzo started setting up the SR3 rack (with help from Yamamoto-san). * We received the real BS optic and gluing tools, and glued the disks and rods into the modified magnet jigs. We also tried the re-made secondary prisms in the gluing jigs and made shims to hold them more securely. |
==== Report for week of 12/25 ==== * Hirata-san got the L-brackets machined and washed, and installed them on the IM ring bars. * Shoda-san recovered the BS from the power outage on 12/25. * Miyakawa-san fixed an issue with the SR2 RTM which had prevented it from running. * Shoda-san, Hirata-san and Kozu-kun weighed the IM without ballast masses, and then added the lower masses and installed the IM on the assembly frame. * They cleaned the assembly frame and installed new jack receptacles on the load gauge adapter. * They installed the winch system on the IM, and inspected the clamp pieces for possible scratches. * They ran cables for the SR2 steppers and OSEMs. * They calibrated the BF LVDT. |

| At Mitaka (Fabian and Hirata-san): * Hirata-san shipped the optic and gluing tools to Kamioka. * Hirata-san did drawings and RFQs for IM/BF/SF ballast masses * Fabian worked on the SRx assembly frame. |
==== Report for week of 1/4 ==== * Mark fixed a number of errors with the Type B screens. |
| Line 23: | Line 19: |
| ==== Plan for week of 7/18 ==== Full team at Kamioka from Tue-Fri, except Hirata-san (Tue-Wed only). * Glue prisms/magnets on BS. * Dismantle suspension. * Finish setting up filter service area (mostly already done by Mirapro). * Move BF to filter service area, start rebuild. |
==== Report for week of 1/9 ==== * We weighed the mirror in its box (and later the empty box), and the RM. * Fabian worked on the SR2/SR3/SRM mass budget and did an inventory of spare ballast masses. * We hung the SR2 and RM. * We assembled the bottom section of the security structure below the RM. * Hirata-san gave up on waiting for a third quote for the blades and blade parts and started the ordering process. * Hirata-san got rod cable clamp parts from Takahashi-san and worked on drawings for the improved BS vertical and yaw adjusters. |

| ==== Plan for week of 7/24 ==== Full team at Kamioka from Mon-Fri, except Hirata-san (Tue-Fri) and Enzo (vacation). * Finish BF rebuild. * Recheck alignment of assembly frame and centering of optical table. * Install IM, suspend BS and RM. |
