VIS Type B To-Do List
Archived items are at ../ToDoOld.
Every Week
Facilities
- Vacuum and roll floor.
- Wipe ladders.
- Tidy tools, parts.
Get stuff from ../WishList
2019-02-12
- Monday is public holiday.
Etc
- Wipe inside tanks with Vectra-Alpha wipes and ethanol.
Choose optimum BIO Config board switch settings for all OLs. See D1302081 for what each switch does. Four of them are gain stages (24 dB, 12 dB, 6 dB, 3 dB), and three are filters (all 1 Hz zero, 10 Hz pole). Please clarify the switch numbering and functions (switch "1" = circuit board B0 = group 1, filter A1; position 1 = enable?), make a cheat sheet and put a copy in each rack.
BS
Check focus of BS camera.
- Debug stepper remote enable.
SR2
- Install GAS filter control loops.
- Debug stepper remote enable.
Get rid of SR2 cable reel (shutdown FE and rack, replug everything into new power strip, start up rack and FE).
Split model.
SR3
Debug stepper remote enable.
Split model.
SRM
- Debug OL, especially whitening filter. Note that WF S1808108 has a mysterious note on its JGWDoc page suggesting it may have a fault.
- Set up LEN OL (if/when 3D QPD stage arrives).
- Debug stepper remote enable.
- Check BIO connections for possible swap of GAS/IP.
Real-Time Model
- Restart k1vissrmt (Wednesday during maintenance??):
- Re-convert filter files. (?)
Stop SRM Guardian (just stop it dead - don't transition to SAFE; don't let it meddle at all).
Make fresh safe.snap.
Note all TEST and OPTICALIGN offsets.
Put large ramp times (≈30++ s) in all DAMP, TEST and OPTICALIGN filters.
Turn off all DAMP, TEST, and OPTICALIGN filter offsets and master switch.
Restart k1vissrmt. If there are gross problems, consider restarting the whole FE.
Restore safe.snap.
Debug OVERVIEW, IP and WD screens (check for white channels etc).
- Restore OPTICALIGN offsets (if necessary), transfer TEST offsets to new ALIGN filters and set long ramp times.
Set new WD thresholds for IP LVDT and ACC.
- Enable all DAMP, ALIGN, and OPTICALIGN offsets.
Make sure SRM Guardian is pointing to generic Type B Guardian.
- Adjust Type B Guardian code to set long ramp times on all DAMP, ALIGN and OPTICALIGN filters. Wrap the ALIGN stuff in an if block for now to not break BS/SR2/SR3.
- Reenable Guardian if/when satisfied.
Rebuild and restart k1visbst and initialize/test as for SRM.
Create new k1vissr2t, k1vissr2p, k1vissr3t, k1vissr3p based on k1vissrmt and k1vissrmp. Be sure to update DCUID numbers:
SR2 FECT=54, FECP=55
SR3 FECT=56, FECP=57
SRM FECT=58, FECP=59
Update DCUID numbers also in /opt/rtcds/userapps/release/vis/common/medm/vissr2_overview_macro.txt and vissr3_overview_macro.txt.
Rebuild, restart k1vissr2t, k1vissr2p, k1vissr3t, k1vissr3p and initialize/test as for SRM/BS.
For SR2, just before restarting with the new real-time models, power the whole front end down and replug everything into the new power strip.
Turn off all DC-powered boxes.
Shut down the FE computer using the web server at http://10.68.99.171.
Turn off the IO chassis using the switch on the front.
Turn off the DC power supplies.
Replug all AC-powered stuff (DC supplies, IO chassis, signal generator, routers) into the new power strip that is already there.
Restore everything in reverse order.
Reset the signal generator: 10 kHz, 5 Vpp, sine wave, ON.
Guardian
Make all Guardians point to TYPEB.py.
Create a BURT .req file to backup the ALIGN settings for IP and GAS.
Create a BURT .req file to back up the OPTICALIGN settings for the payload.
Add UI to the MEDM screens to run BURT with either the ALIGN and OPTICALIGN .req files and generate .snap files with suitable names.
Make sure the SAFE state turns off all ALIGN and OPTICALIGN offsets with long ramp times.
- Have the transition from the SAFE state to the DAMPED state load the ALIGN offsets with long ramp times.
- Have the transition from the DAMPED state to the ALIGNED state load the OPTICALIGN offsets with long ramp times 9and also enable damping).
Documentation and Operation Manual
- Add useful info from Enzo's notebook to BSData.
Minor Tasks
Mechanical
- Put pointy-tipped screw in RM trolley for BS
Electrical
- Update BS Circuit diagram, D1503600
Note removal of LED/PD on TM OSEMs.
- Organize stepper reset system and watchdog BIO.
- Include information on assignment of channels to feedthrough positions.
- Reflect gender-changers and non-flipping feedthrough adapters.
- Reflect actual cable lengths.
- Include LVDT pin size (1 mm).
- Include Stepper pin size (1.6 mm).
Undo renumbering of IP items.
Page 10: "DIO Card # 0" should be "DIO Card # 1"
Include OutConfigBoards on OL page (Sheet 18).
Update HPCD section to reflect:
All three GAS channels are on HPCD #1 and DIO Card #2, CNB cables, Sheet 13.
Three IP channels are on HPCD #0 and DIO Card #2, CNA cables, Sheet 15.
Real-time and SUMCON models
- Create SUMCON models for full BS and major installation milestones.
Create controls design description (cf 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.
One Day, If Ever Needed
BS
- Tune BS LBB (adjust table height, damper height) - DON'T BOTHER (unless there's an excuse to open the lower half of the tank).
- Replace BS F0 thrust bearing and yaw adjuster - BIG JOB, DON'T BOTHER (unless lack of yaw adjustment becomes a major problem).
- (Continue to) soak the sapphire prisms off the dummy BS for reuse on the SRM metal mass.
SR3
- Replace chipped magnets (12x12x12 mm) in SR3 IP, H1 and H2.
SRM
- Install Enomoto-kun's beam target plate (if/when available).
- Find two geophone cables used by Okutomi-san. (I looked in the second floor EXV room but didn't find them - Mark.)
- Find one geophone cable ordered for SRM but missing.
- Rearrange miswired geophone cable.
- Rebuild defective geophone cable.
- Put FC on SRM-W and install it in its holder with 1.4 mm shims ready for possible use.
