| ==== 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 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. |
