20190306 DX Flat Measurements with 4D

KL_v26 Configuration

16:42 4D aligned
  • flat ../20190206_102708/flattening_result.sav
  • A lot of Astigmatism
  • Create mask 20190306_163900

18:00 Start 4D server
  • Start InterferometerCtrl client
  • flat default_kl_v26_60el.sav
  • 16.8 um of Astigmatism. Seems like a lot
  • Remove Astigmatism
    • AdOpt>set_plot, "X"
    • AdOpt>print, opt_int_mat_reduce2(20, track='20190205_063210')

18:24 Flat ../20190206_102708/flattening_result.sav
  • 2.5 um asitigmatism
  • 90 nm rms (low order removed)
  • 2 image Intial_90el
  • AdOpt> print, opt_int_mat_reduce2(10, track='20190205_063210')
  • 420 nm rms (applied a bunch of trefoil(?))
  • 2 images 90el_m10_*

18:42 Flat ../20190206_102708/flattening_result.sav
  • 463 modes
  • high forces on act 556
  • 2 images act_556_*
  • Rest and set again and 556 is OK. 634 modes applied

19:43 Test manual astig remove from AdSec Control GUI
  • Flat

  • Apply -0.9 Z6 on AdSec Control GUI
  • 65 nm rms

19:53 Move to 75 El
  • delta M2 = -0.03, -0.30, 0, 61, -7
  • A bunch of Astigmatism
    • 11.03
  • Apply 5.5 more z6
