20220418_DX_Day DX AdSec Flattening with New 4D, Day 3

Starting @ 9:40

05:35 Looks like 4D head is out of focus.
  • Need to send someone to the lower treehouse to focus

05:39 Measure new reconstructor
  • AdOpt> print, i4d_opt_intmat(0,20,AMPRMS=100e-9)
    • 20220418_174412
  • IDL> print, idl_4d_produce('20220417_211519')
  • IDL> print, if_redux_new(/modal,'20220417_211519', plot=4, /force)
  • IDL> print, build_int_mat(['20220417_211519'])
  • AdOpt >print, opt_int_mat_reduce2(40, track='20220417_211519') * failed

06:30 LeRoy changed focus for us. Looks much better

06:33 Start from mode 0
  • modes 0-20 20220418_183323
  • modes 21-50 20220418_184838 (improved the edge at 3:00)
  • modes 51-100 20220418_190146
    • 20220418_191438/flattening_result.sav
    • 166 nm rms (0.264 waves)

07:03 Guido says actuators 170 and 171 are pieces of shit
  • high forces
  • 168, 169 are on DSP #42
  • DSP board #21

07:19 See how hard it will be to make a new flat from set_flat(/no_flat) when we introduce new actuators
  • AdOpt> print, fsm_rip()
  • AdOpt> print, fsm_set_flat(/no_flat)
  • AdOpt> print, i4d_opt_intmat(0,11,AMPRMS=100e-9) (with smaller mask)
    • 20220418_193959

07:40 Guido and Xianyu add Actuators that were put back
  • 4
  • 260
  • 565
  • 367
  • 340
  • 470
  • 218
  • Actuators removed in position: 170, 171

08:14 Measure 11 mode recon with reduce mask size
  • 20220418_201424

08:26 Measure recon with bigger mask
  • modes 0-20 20220418_202651 (only 11 modes applied)
  • mode 21-50 20220418_203840 20220418_204815/flattening_result.sav

08:51 Measure recon with full mask
  • Modes 0-100 20220418_205130 best yet 20220418_204815/flattening_result.sav

09:11 Better central mask and 250 amperes
  • modes 0-100 20220418_211059
    • 20220418_212720/flattening_result.sav
    • 0.314 waves, 200 nm rms
  • modes 101-200 20220418_212734
    • 20220418_214309/flattening_result.sav
    • 0.244 waves, 154 nm rms
  • modes 201-300 20220418_214440
    • 20220418_221347/flattening_result.sav
    • 0.132 waves
  • modes 301-400 20220

10:53 Reset actuator list to the list from the last 4 nights. Set default.sav to
  • 20220418_214309/flattening_result.sav
  • 0.207 wave
