[[#EveryWeek |Every Week]]

[[#ComingWeeks |Coming Weeks]]


== Every Week ==
=== Facilities ===
 * Vacuum and roll floor.
 * Wipe ladders.
 * Tidy tools, parts.
 * Get stuff from [[../WishList]]


== 2017-10-02 ==

=== Main Assembly Sequence ===
 * Account for second bubble level (might be on BF).
 * Borrow portable hard drive.
 * Clean up sticker residue and magic marker writing.
 * Remove LVDT modules; identify and replace screws.
 * Check that all in-air cables are labeled.
 * If possible, reroute cable to eliminate need for fifth feedthrough.
 * Debug all electronics, especially actuation.
 * --(Check IP yaw.)--
 * --(Recheck centering of suspension in assembly frame.)--
 * Measure IP period; adjust ballast mass.
 * Calibrate all LVDTs (Enzo, Mark). --(BF)--, --(SF)--, --(PI-GAS)--, PI-H1, PI-H2, PI-H3
 * Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
 * Set all EQ stops to proper clearance.
 * Install small KOACH filters on LBB.
 * Remove First Contact.
 * Cable optical lever (Simon, Enzo)
 * Align optical lever (Simon)
 * Get ready for full TFs.

=== Software ===
 * Enter new IP matrices and do safe.snap.
 * Get pico drive screens fixed (Miyo-kun)
 * Update real-time model to number channels from #0.
 * Remove old OL stuff; add link to new OL stuff.
 * Remove unused screens.
 * Sort out SVN.

== Tasks Not To Forget ==
=== Major Tasks ===
 * Update BS Install Procedure with screenshots from new on-assembly-frame 3D CAD.
 * Finish assembly drawing for LBB and LBB damper ring and post on JGWDoc (Hirata-san).
 * Figure out how to make PI yaw adjustment reliable.

=== Minor Tasks ===
==== Mechanical ====
 * Get clean bag laundered.
 * Put pointy-tipped screw in RM trolley for BS
 * Return/replace borrowed parts:
  * Lock washers for LBB dampers
  * Temporary ballast mass (dog clamps) in BF.
 * Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match.

==== Electrical ====

==== Real-time and SUMCON models ====
 * Create SUMCON models for full BS and major installation milestones.
 * Create controls design description (cf [[https://dcc.ligo.org/LIGO-T1100378/public|LIGO-T1100378]]).
 * Make table of ADC/DAC assignments and check for consistency with D1503600 and k1visbs (Enzo, Mark)
 * Understand/document/debug Kokeyama-san's DIO stuff.
 * Measure LPCD and HPCD output filter response.
 * Design and install software compensation filters for LPCD and HPCD output filters.
 * Design and install GAS drift compensation filters.
