<<Anchor(RealBSHang)>>
== Real BS Hang Tasks ==
=== Major Tasks ===
 * Final ballast mass design/production for BF and SF (Fabian, Hirata-san).
 * Get final OSEM cables (six of 1.7 m, two of 2.2 m, two of 2.4 m; Sato-san).
 * Possible rebuild of BF and/or SF
  * Set up build/test stand for filters.
  * Get filter test weights.
  * Find spare BF blade(s).
 * Prepare real BS:
  * Coordinate with Hirose-san.
  * Book transport of mirror (Kashiwa to KAGRA)
  * Gather mirror box, gluing supplies, prisms, magnets, new flags, new flag jigs.
  * Solve problem of lack of scribe line on one side of BS (Mark, Hirata-san).
  * Organize cleanroom gear for Kashiwa trip(s).
  * Put magnets in flags.
  * Glue flags/prisms at Kashiwa.
 * Reclean stuff:
  * PI (remove Kapton tape etc, etc).
  * LLB damper stuff, especially Cu segments.
 * Try rearranging arc weights to make room for magic wand (3D CAD or actual weights; Fabian or Hirata).
 * If needed based on previous, order longer threaded rods for arc weights on PI (Hirata).
 * Calibrate PI vertical LVDT.
 * Set yoke on PI vertical LVDT (if necessary).
 * Calibrate PI horizontal LVDTs.
 * Unlock BF keystone and try running BF fishing rod to fix sag problem.

=== Minor Tasks ===
==== Mechanical ====
 * Get clean bag laundered.
 * Swap out temporary ballast mass in BF, SF.
 * 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.
 * Check inside SF for lost ruler.
 * Tighten PI yaw return spring.
 * Get Cu O-rings for feedthroughs.

==== Electrical ====
 * Decide final in-vacuum and in-air cable routing (Enzo).
 * Calibrate all LVDTs (Enzo, Mark).
 * 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 6 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]]).
