Night work

led-green Get PSF working

04:10 Restart PSFR
  • Stop PSFR
  • Change machine to tcs2
  • Start PSFR * Configuration for M1, M2 and M3 correctly read

04:19 Authorize NONE:RETROREF@4DInt
  • Successful
  • OSS has not been restart so position.conf not read
    • Collimate M3 on PSFR Tertiary GUI
    • Old values used
    • Set Global Offsets so sum is -510, -760, 0, 56.41
      • Update button
    • Request someone to stop/start OSS subsystem

led-green Save a flat, even if poor, and set at default.sav so SetFlatAO on AdSec Control GUI can be used

04:59 Old default.sav -> 20180219_Flat_400Mode1.sav

05:03 Backup old flats
  • cd /local/aomeas/adsec_calib/
  • cp -f flat ts3_old_flat

05:04 Cleanup flat directory
  • cd flat
  • rm -fr 2018*
  • cd Applicable
  • rm -fr 2018* (and lbti flats)

05:45 Save flat and make default
  • AdOpt> print, fsm_save_shape('ts3_no_flat.sav')
    • saved file /local/aomeas/adsec_calib/flat/20180826_054212/ts3_no_flat.sav
    • made link /local/aomeas/adsec_calib/flat/Applicable/ts3_no_flat.sav -> /local/aomeas/adsec_calib/flat/20180826_054212/ts3_no_flat.sav
  • cd /local/aomeas/adsec_calib/flat/Applicable
  • rm default.sav (old link)

    • Success
    • 647 modes
    • DX AdSec shape remain the same
  • Should be able to use the SetFlatAO button on the AdSec Control GUI

05:54 Test GUI button
  • print, fsm_rip()
  • SetFlatAO button
    • Set shell
    • Load flat /local/aomeas/adsec_calib/flat/Applicable/default.sav

  • no luck

07:00 Start client on dxadsec machine

07:10 Check that server is working
  • aoidl
  • IDL> @startup-onlycom
  • IDL> a = get_img4d()
    • Success
  • IDL> help, a
    • a DOUBLE = Array[990, 1002]
  • Works fine

07:20 Collect Hexapod IM
  • IDL> print, hexapod_opt_calib()
    • a bunch of data sets collected: 0 0, 0 -1, 0 +1, 0 0 etc
    • Data saved to /local/aomeas/adsec_calib/hexapod/20180826_073410

07:38 Measure Hex motion
  • IDL> print, hexalign()
    • 0.25, -2.71, -0.066, 273, 22, 0
    • applied most of this manually
    • 0.55, -0.5, 4.94, 33.14, 23.15, 0

07:46 Hex Motion
  • IDL> print, hexalign(/apply)
    • automatically applied -0.03, -0.65, -0.0069, 67.74, -3.08, 0
  • Hex now 0.519, -1.154, 4.93, 100.87, 20.04

09:02 After trying to get illumination to be more even by Tipping M3 and realigning M2, to no avail, when back to original M3, m2 positions
  • M3 -500, -760, 0, 65.41
  • M2 0.908, -1.413, 4.939, 123.82, 61.31, 0

led-green Collect 4D vibration data and analyze to understand DX environment

09:09 Capture Noise data. 1000 frames
  • comm4d.capture(1000, '20180826_090900_noise')
  • 20180826_091000_noise
  • 20180826_091100_noise

09:27 Reduce
  • comm4d.produce('20180826_090900_noise')

led-yellow Collect new 5 iteration and 20 iteration FF Matrix and install

led-yellow Collect low order Mirror Mode Interaction matrix and use to improve flat. Up to 30 modes?
