[[#RealBSHang|Preparation for Real BS Hang]]


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

== 2017-09-04 ==

=== Main Assembly Sequence ===
 * Crane out SF.
 * Raise BF cap and retrieve lost hex cable clamp PEEK piece.
 * Crane in SF.
 * Install SF-BF rod with hex cable clamp.
 * Route cables via hex cable clamp up to below SF.
 * Adjust BF ballast mass for total weight and pitch/roll.
 * Look for missing screw from SF damper Cu segment in washed screws bag and reinstall.
 * Calibrate SF LVDT.
 * Install SF main ballast mass.
 * Cable and test SF fishing rod stepper.
 * Add SF cap.
 * Lift and weigh SF/... section.

=== In parallel, time permitting ===
 * Rearrange arc weights on PI to allow installation of magic wand.
 * Check that we still have all LBB parts (there was an issue with borrowed lock nuts).
 * Rearrange magnets on SF damper magnet ring for full three Cu segments.
 * Find Ni-plated rods for SF damper magnet ring and do fit check.
 * Find PI-SF rod with 8 mm heads and matching receptacles and do fit check.
 * Lay more new in-air cabling.
 * Wipe LLB damper parts with ethanol.
 * Get Cu O-rings for feedthroughs.
 * Figure out how to tighten PI yaw return spring.

== Real BS Hang Tasks ==
=== 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).
 * Get pico drive screens fixed (Miyo-kun)
 * Calibrate PI vertical LVDT.
 * Set yoke on PI vertical LVDT (if necessary).
 * Calibrate PI horizontal LVDTs.

=== 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.
  * --(Wide-mouth OSEMs from RM to Akutsu-san)--
 * --(Adjust height of crossbars below BF.)--
 * --(If possible, fix galled pole in BF level of EQ stop.)--
 * Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match.

==== Electrical ====
 * Decide final in-vacuum and in-air cable routing (Enzo).
 * Calibrate all LVDTs (Enzo, Mark). --(BF)--, SF, PI-GAS, PI-H1, PI-H2, PI-H3
 * --(Remove cling wrap in BF and install vacuum-compatible heat shrink.)--
 * --(Remove cling wrap on connections for PI vertical stepper and install vacuum-compatible heat shrink (needs wider diameter heat shrink or smaller pins).)--
 * --(Rewire PI horizontal steppers with vacuum-compatible cable)--.
 * --(Adjust yoke on BF to put top of secondary at 3.5 mm above top of baseplate (or to give ≈0 counts at nominal height).)--
 * Adjust yoke on SF to put top of secondary at 6 mm above top of baseplate (or to give ≈0 counts at nominal height).
 * Adjust yoke on PI to put top of secondary at TBD mm above top of baseplate (or to give ≈0 counts at nominal height).

==== 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.
 * --(Create a proper DAC Monitor MEDM screen.)--
 * --(Improve ADC Monitor MEDM screen.)--
