Flattening commands and Interaction Matrices: creation of Cx, obtaining shapes Sx

Keywords:
  • Temp ATT: command given to the PID controller
  • T Adsec: temperature read on the cold plate inlet
  • Intmat: located in $ADOPT_MEAS/adsec_calib/flat/
  • Electrical data: located in $ADOPT_MEAS/adsec_calib/flat/xxxxx/flattening_result.sav
  • Optical data: located in $ADOPT_MEAS/adsec_calib/4d/flattening/xxxxx.h5
  • WFE: residual wf error after 4 terms removal (pisto, tip tilt power)

Housekeeper variables:
  • Main inlet and Main Outlot are switched
  • Water CP inlet and Water CP outlet (THIS IS THE REFERENCE TEMPERATURE FOR THE TEST)
  • Fluxrate is read as 0. ATT fluxmeter reads 0.25 l/s
  • before flattening with an old intmat, a shape obtained at a different temperature is loaded (300 nmRMS approx...)
The Adsec Swing Arm cabinet is not cooled, to avoid condensation
