| ==== Report for week of 9/24 ==== * Monday 9/24 was a holiday (Autumn Equinox). ===== SR2 ===== * We moved all the SR2 feedthrough and in-vacuum and in-air cables. * We tested all the OSEMs and most of the LVDTs. We still need to run power to the pico drivers, and test them and the steppers. * We unlocked and mostly realigned the suspension. The IM is sitting lower than before but can be brought up to nominal height with BF GAS offset, without any signs of anything touching. The IM also has a moderately large pitch (2.8 mrad according to the OSEMs, about 1 mrad according to the OL) and some roll, which we expect to be able to correct with some pico adjustment. The horizontal IM OSEMs are well-centered (so there is no yaw misalignment). |
==== Report for Golden Week ==== * Mark monitored vent and pumpdown, and worked on vistools.py. |

| ===== SRM ===== * We made another attempt to set the pitch of the SRM, but weren't satisfied with how close we were able to get (target 20 mm low, achieved 23 mm), so we didn't tighten the clamps or continue to setting the pitch of the RM. |
==== Report for the week of 5/6 ==== * Lucia and Terrence got the blending working for the IP LVDTs and geophones. * Terrence and Mark modified the models and MEDM screens to add a new IP block, IDAMP, for damping using the blended signal with inertial information, and a new DAMPMODE block for ramping smoothly between IDAMP and the old DAMP. * Mark worked on vistools.py, improving the support for cdsMuxMatrix blocks (e.g., OSEM2EUL) and adding support for cdsRampMuxMatrix blocks (e.g., the newly introduced DAMPMODE). He also created two sets of unit tests, unittest.py and unittest.sh, for the two modes of use (as a Python module in other Python programs, and as a command-line utility in bash). |

| ==== Plan for week of 10/1 ==== * Mark, Hirata-san, Fabian, Panwei at Kamioka Mon-Fri. ===== SRM ===== * Set pitch of SRM and RM, tighten clamps, remove winch system. * Weigh IM/... section. * Build up SS to BF level. * Add BF. * Suspend IM and tweak height/balance. * Cable/test BF. * Install IRM. * Install/cable/test IM OSEMs. |
