note: in the folder meas/disturbance/2009_08_10 you will find the configuration files for the measurements: they have been produced adding the keyword /SAVE to the routine that produce the disturb temporal series

18:00: actuators close to the central membrane miscalibrated --> shell ripped and set again

two dust grains found on the folding mirror during the post processing affecting the WF reconstruction. they have been removed (22:00)

Time: 00:01

Measurement of noise levels, set '_c'

  • With TOWER cooling OFF:
    • tower cooling switched off
    • hextrac(/APPLY)
    • Disturbance disabled on W GUI
    • loop closedon W GUI
    • directory: 2009_08_10_noise_tower_off_c
    • number of 4D mesurements 150
    • loop opened on W GUI
      • this measurement just for checking the noise level before start extensive measurement
      • the measurement showed good
max tilt:20nm PtV

Measurement of noise level with tower cooling off, set '_d'

  • With trim pixels 1 (4D configuration):
    • tower cooling still switched off
    • hextrac(/APPLY)
    • Disturbance disabled on W GUI
    • loop closedon W GUI
    • directory: 2009_08_10_noise_tower_off_d
    • number of 4D mesurements 150
    • loop opened on W GUI
      • this measurement just for checking the noise level before start extensive measurement

We decided to have at least a trimming of 1 pixel of the pupil

max tilt: 14nm PtV

Measurement of noise level with Mirror Cooling off, set '_e'

  • With trim pixels 1 (4D configuration):
    • tower cooling still switched off
    • hextrac(/APPLY)
    • Disturbance disabled on W GUI
    • loop closedon W GUI
    • directory: 2009_08_10_noise_mirror_off_e
    • number of 4D mesurements 150
    • loop opened on W GUI
      • this measurement just for checking the noise level before start extensive measurement

max tilt: 11nm PtV (same behavior as before)

From now on the cooling of the mirror is kept ON

4D trim is set to 1pix

We notice spiky noise on one edge of the pupil (bottom-left). We moved the mask about 1-2 pix top-right to try to fixor reduce the problem.

The next short set of mesurement is taken for checking the fix.

Measurement of noise level, set '_f'

  • With trim pixels 1 (4D configuration):
    • tower cooling still switched off
    • hextrac(/APPLY)
    • Disturbance disabled on W GUI
    • loop closedon W GUI
    • directory: 2009_08_10_noise_tower_off_f
    • number of 4D mesurements 150
    • loop opened on W GUI
      • this measurement just for checking the noise level before start extensive measurement

max tilt ptv: 17nm

mask moved a bit more in the same direction before next measurement

Measurement of noise level, set '_g'

  • With trim pixels 1 (4D configuration):
    • tower cooling still switched off
    • hextrac(/APPLY)
    • Disturbance disabled on W GUI
    • loop closedon W GUI
    • directory: 2009_08_10_noise_tower_off_g
    • number of 4D mesurements 150
    • loop opened on W GUI
      • this measurement just for checking the noise level before start extensive measurement

max tilt PtV: 17nm

No enhancement of the mesurement moving the mask: the spiky noise is possibly due to the static pattern introduced by the frame-grabber when the external trigger is used. RESTORED THE ORIGINAL MASK, TRIM to 1 and FILL to 2.

The configuration is saved as default and stored in the file 2009_08_10_default_h.ini (C:/4D/conf)
