ES= External laser Source at 532nm (polarized), IS = Internal broadband LED Source, CU = Calibration Unit narrowband LED source

Procedures

  1. Bring the corresponding LGSW system all the way up to "READY_TO_CALIBRATE_ON_INTERNAL SOURCE" from the Arbitrator GUI:
    • Check that all processes are up and running on monit.
    • Put LAS and LAN in simulation (AARB GUI > Expert tab > Commissioning tab).
    • Power Up > Set Up > Start Up
    • Select "Internal diodes" as Light source. Click Apply. (This will turn on the internal diodes sources at 0.1 A).
    • Open CCD Viewer. Check that spots are visible.
    • Click "Prepare".
  2. Select the corresponding Pupil Motors positions ( Internal diodes ) using the LGSW LAB GUI, tab "Motors" and apply by pressing "Move All Absolute" for each pupil. NOTE: Also, it can be used another source.
  3. Check that pupils are properly aligned with the sub-apertures in CCD Viewer. Adjust if needed.
    • SX: [360, 380]; [350, 400]; [640, 380]

from argos.lgsw.tools.pockels_cells_transmission import PockelsCellTransmission
pct= PockelsCellTransmission(argos)
snapshotTagList=pct.acquireDataForComputeTrasmission(0.5, 2.0, 4, 'PCT')
print(snapshotTagList)

To analyze data open argos_dx_snapshot_analyzer or argos_sx_snapshot_analyzer .

from argos.snapshot.analyzer.analyzer_set import Sandbox
ds=terminal.set(<firstSnapshotTag>, <lastSnapshotTag>)
sbox=Sandbox(ds)
res= sbox.computeTrasmission()
map= sbox.computeTrasmissionPerSubap()

Understanding the results:

  • Plot (left side): Average supression rate should be >100 for each cell.
  • Map (right side): All subaps must have >70-80 suppression.
