| ==== Report for week of 10/29 ==== * 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.
