| ==== Report for week of 9/17 ==== * Monday 9/17 was holiday. * We optimized the trim mass on the SF to get more balance torque with less total mass. We now have a reserve of 480 g for the yaw pico. * We set the SF damper gap to 6 mm. * We set the SR2 pitch with the optic lever, aligned the IRM, and set all the OSEMs to have good clearance and midrange output. * We locked the SR2 suspension, craned it into the tank and hooked the LBB damper rings (but not the LBB yet). * With help from Ohishi-san, we removed the First Contact from SR2. * Mark did an audit of all the electronics boxes and updated the item list and S-number file cards on JGWDoc. * Mark added some thin arc weights to the inventory and finalized the number of various types to order (8*38 mm + 9*10 mm). * Panwei copied control filters over from the SR3. ==== Plan for week of 9/24 ==== * Monday 9/24 is holiday (Autumn Equinox). * Mark, Hirata-san, Fabian, Panwei at Kamioka Tue-Fri. ===== SR2 ===== * Move SR2 in-air cables. * Unlock and realign suspension. ===== 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. |
==== Report for Golden Week ==== * Mark monitored vent and pumpdown, and worked on vistools.py. |

| ==== Plan for week of 10/1 ==== * Mark, Hirata-san, Fabian, Panwei at Kamioka Mon-Fri. ===== SRM ===== * Cable/test BF. * Install IRM. * Install/cable/test IM OSEMs. |
==== 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). |
