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.
BS
- 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
- Set up LEN OL (if/when 3D QPD stage arrives).
- Debug stepper remote enable.
- Check BIO connections for possible swap of GAS/IP.
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).
SR2
SR3
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.
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, FECT=55
- SR3 FECT=56, FECT=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.
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
