[[#EveryWeek |Every Week]]

[[#ComingWeeks |Coming Weeks]]


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


== 2017-10-16 ==

=== Main Assembly Sequence ===
 * --(Borrow portable hard drive.)--
 * --(Remove sticker residue and permanent marker writing on PI.)--
 * --(Fix broken and unreliable connections on IP LVDTs.)--
 * --(Reconfigure the stepper motor cables for Miyo-kun.)--
 * Wipe any rust from around IP LVDTs.
 * (If Enzo thinks it necessary and there's time) adjust IP LVDT mechanical offsets to maximize usable range and recalibrate.
 * --(Add IP LVDT gains and offsets to IP_LVDTINF filter blocks.)--
 * Calibrate IP LVDT actuation against IP LVDT sensing.
 * --(Install damping filters for IP LVDTs.)--
 * Adjust gains and debug damping for IM OSEMs and GAS LVDTs.
 * Modify IP LVDT damping filters to include set point.
 * --(Install and debug IP LVDT and geophone diagonalization matrices.)--
 * (Time permitting) Try adding mass to IP.
 * Work with alignment team.
 * Work with Mirapro on SR LBB and tank installation (Hirata-san, from Wed)
 * Work with Miyo-kun to get user interface for stepper motors.
 * --(Calibrate IP FR actuation against IP LVDT sensing.)--
 * SR procurement.
 * --(Lower LBB by 17.5 mm; suspend and rebalance after removing table KOACH filters.)--
 * --(Reroute cable to eliminate need for fifth feedthrough.)--
 * Set all EQ stops to TBD clearance.
 * Measure IP period; adjust ballast mass.
 * Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
 * 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.

== 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.
