[[#EveryWeek |Every Week]]
[[#ComingWeeks |Coming Weeks]]
== Every Week ==
=== Facilities ===
* Vacuum and roll floor.
* Wipe ladders.
* Tidy tools, parts.
* Get stuff from [[../WishList]]
== ASAP ==
=== Pumpdown Prep ===
* Prepare BS Chamber
* --(Remove non-vacuum-compatible ballast from LBB.)--
* --(Check for lost tools.)--
* Wipe down all accessible areas inside tank with Vector Alpha wipes and ethanol.
* Help Type Bp Team
* --(Add screws to cables at PR2 feedthroughs.)--
=== Main Assembly Sequence ===
* Necessary for phase-I★★★
* --(Modify IP LVDT damping filters to include set point.)--
* '''''EXCHANGE YAW/VERT FRs at F0'''''
* Check IP BIO is working or not.
* Necessary for phase-II★★
* Calibrate IP LVDT actuation against IP LVDT sensing. (Klog 3553? http://klog.icrr.u-tokyo.ac.jp/osl/?r=3553)
* Design PI Sensor blending filter.
* Re-calibrate F0 GAS LVDT
* Tune the LVDT sensitivity
* Measure IP period; adjust ballast mass.
* At some point (remotely)★
* Improve OL offloading.
* Improve GAS offloading.
* Spectral analysis of Oplev.
* Design, install angular lock servo using OL. (Almost done for phase-I)
* Adjust gains and debug damping for IM OSEMs and GAS LVDTs. (Almost done for phase-I)
* Subtract DC level of Geophones.
* Spectra analysis of PI sensors (PI LVDTs and Geophones).
* Calibrate IP LVDT sensing against IP LVDT actuation, IP FRs.
* Set all EQ stops to TBD clearance.
* Modify the model for IP coil driver control
=== Documentation and Operation Manual ===
* Add useful info from Enzo's notebook to BSData.
== Tasks Not To Forget ==
=== Major Tasks ===
* Move safety bars from BS AF area to SR2 area.
* Close hole in floor above BS AF area.
* 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.
