<<Anchor(EveryWeek)>>

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

<<Anchor(ComingWeeks)>>

== 2017-10-10 ==

=== 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 screws.)--
 * --(Check that all in-air cables are labeled)--.
 * If possible, reroute cable to eliminate need for fifth feedthrough.
 * --(Debug all electronics, especially actuation.)--
 * Measure IP period; adjust ballast mass.
 * Calibrate all LVDTs. --(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 TBD clearance.
 * --(Install small KOACH filters on LBB.)--
 * --(Remove First Contact.)--
 * --(Cable optical lever (Simon, Enzo))--
 * --(Align optical lever (Simon))--
 * Get ready for full TFs.

=== Etc ===
 * Move stuff out of PR2 area.
 * Tidy/label parts.
 * Move safety bars from BS AF area to SR2 area.
 * (Put up safety bars in SR3 area.)
 * Close hole in floor above BS AF area.

=== Software ===
 * --(Enter new IP matrices and do safe.snap.)--
 * Send stepper driver info to 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.
 * --(Add support for comments to SUMCON.)--
 * Create SUMCON model with values commented.
 * Derive matrices for IP FRs.

=== Design ===
 * Finalize redesign of IP yaw adjuster.
 * Design better F0 FR adjuster.

<<Anchor(RealBSHang)>>
== 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 ====
 * Put pointy-tipped screw in RM trolley for BS
 * Return/replace borrowed parts:
  * Temporary ballast mass (dog clamps) in BF.

==== 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.
