<<Anchor(EveryWeek)>>

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

<<Anchor(ComingWeeks)>>

== 2017-11-13 ==

=== Main Assembly Sequence ===
 * --(Realign OL.)--
 * --(Cover OL with foil.)--
 * --(Offload IP P&Y offsets to picos.)--
 * Diagonalize OL.
 * Spectra analysis of Oplev.
 * Design, install angular lock servo using OL.
 * Adjust gains and debug damping for IM OSEMs and GAS LVDTs.
 * Calibrate IP LVDT actuation against IP LVDT sensing.(Klog 3553? http://klog.icrr.u-tokyo.ac.jp/osl/?r=3553)
 * Subtract DC level of Geophones.
 * Spectra analysis of PI sensors (PI LVDTs and Geophones).
 * Design PI Sensor blending filter.
 * Modify IP LVDT damping filters to include set point.
 * Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
 * Set all EQ stops to TBD clearance.
 * Measure IP period; adjust ballast mass.
 * TFs.

=== Etc ===
 * --(Move stuff out of PR2 area.)--
 * --(Tidy/label parts.)--

=== Software ===
 * Update real-time model to number channels from #0.
 * Do better interface to IP steppers (make a wrapper for Miyo-kun's driver which includes geometry matrix).
 * Sort out SVN.
 * Add support for comments to SUMCON.
 * Create SUMCON model with values commented.

=== Medm screens ===
 * Fix Oplev Damp screens.
 * Enlarge TYPE B IP screen.
 * Remove old OL stuff; add link to new OL stuff.
 * Remove unused screens.

=== Documentation and Operation Manual ===
 * Publish matrices for IP FRs.
 * Publish matrices for BS PI sensors v4.
 * Finish Foton operation Manual.
 * Complete MEDM operation Manual.
 * Pico Motor operation Manual.
 * Add useful info from Enzo's notebook to BSData.

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

<<Anchor(RealBSHang)>>
== Tasks Not To Forget ==
=== Major Tasks ===
 * Move safety bars from BS AF area to SR2 area.
 * Close hole in floor above BS AF area.
 * Wipe any rust from around IP LVDTs.
 * Update circuit diagram.
 * (Time permitting) Try adding mass to IP.
 * 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.
