==== Report for week of 11/12 ==== * SRM * Hirata-san and Mark craned the LBB ring sandwich to the ceiling of the lower half of the tank, and set the heights of the jacks on the upper half. * Fabian and Hirata-san finished the in-vacuum cabling. * Enzo ran DC power to the second SRM stepper driver and did the rest of the in-air cabling. * We're now ready for final tests of the SF/... items and initial tests of the PI items. * Enzo and Fujii-kun built three geophones for SRM. * Mark worked on the height budget. * SR2 * Enzo experimented with [[http://www2.mpq.mpg.de/~ros/geo600_docu/soft/liso/manual.pdf|LISO]] (circuit analysis software which, among other functions, can fit measured TFs with a ZPK model) but then wrote his own fitting software in Python and used it to build Foton models of key TFs of the SR2. (These are in slots FM6-FM8 of the DAMP blocks and should not be accidentally enabled.) ==== To-Do Lists, Schedule ==== * [[KAGRA/Subgroups/VIS/TypeB/ToDoBS]] * [[KAGRA/Subgroups/VIS/TypeB/ToDoSR]] * [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=7779|JGW-L1807779 Type B Schedule (SR)]] |
==== Report for the week of 4/1 ==== * Support of Type Bp * Hirata-san procured the jigs for PRs and Takahashi-san tested one at TAMA. * Hirata-san cleaned up the flags for PR2 and Mark did the one for PRM. * Fabian helped Fujii-kun and Takashashi-san to reglue the flags. * Mark did a lot of maintenance on the MEDM screens: * Made the name of the suspension more obvious (no yellow text!). * Added rack temperature indicators. * Fixed the labels in the ADC screen (to reflect the LEN OL moving from ADC#0 to #1). * Fixed broken links. * Committed files to the SVN. * Mark did maintenance on the Guardian to make it give more helpful messages in the TRIGGER state. Formerly it only checked the user model watchdog and the coil driver watchdog, not the DACKILL, and gave the same generic notification for both. Now it checks all three and tells the user which need attention. * Mark tidied up the cables in the SR2 rack and returned a large pile of no-longer-used cables to the tent. * Mark started a !HealthCheck page on the Operation Manual wiki. Fabian and Mark ==== Plan for week of 4/8 ==== * Mark, Fabian at Kamioka Mon-Fri. * Help with Type Bp. * Health checks on Type B. * Monitor pumpdown. * Work on Type B paper. * Modify RT models and/or Guardian to revert to the SAFE state under control in all but the most extreme emergency situations (rather than suddenly shutting off all output). * Tidy up. * Gather and clean tools. * Gather and organize unused parts and fasteners. |

==== Plan for week of 11/19 ==== * Friday 11/23 is Labor Thanksgiving Day. * Mark, Enzo and Fabian at Kamioka Mon-Thu. * Hirata-san at Kamioka Tue-Thu (Mitaka on Mon for Engineering Promotion Office meeting). ===== SRM ===== * Go/no-go test of all electronics items, especially SF/... section. * Finish vertical height check and adjust SF trim mass as required. * Unlock IP and center roughly. * Check/adjust alignment of SS. * Calibrate IP LVDTs. * Add arc weights and geophones. * Improve centering/tuning of IP and SS alignment. * Disconnect cables at feedthroughs, lock suspension. * Crane into tank. ===== SR2 ===== * Assist MIF team with pico cables and LBB breadboard ballast. * Install SR2 OL pillar and shelf (with AOL supervision)? |
==== Plan for week of 4/15 ==== * Mark at Mitaka 4/15, Kamioka 4/16-18, f2f 4/19. * Fabian at Kamioka 4/15-18, f2f 4/19. |
