9:30: start of operations

FLAO stages @ [-72; -49; 37]mm, created Board setup: 07 NoV 14 - ARGOS Cal Unit

We have a pbl with calibration manager... LB tryes to fix it GOX goes to switch fibers

TS test

We close the loop on ARGOS (no disturb) on 26modes. We move stages to introduce a differential focus between FLAO and ARGOS. We measure it with FLAO and we send the first 10 reconstructed modes to ARGOS. We multiply these modes for the ARGOS IM to get the TS slopes and we sum it to the Slope Offset.

We set gain = 0.01 to the TS slopes. We apply a differential focus of 10um (stage Z moved by +5mm) we apply 1 step of correction and we measure now 9um so we have a factor 10 between measure and differential focus...

PI X Y
Blue 0.55 -0.04
Yellow -0.99 1.02
Red -0.63 1.13

HEXA -3.02 -6.27 4.297 -270 5.3

We set disturb to 1.2" and gain TT= 0.2, gLO= 0.1. We introduce a 10um focus and measure with PYR. Now we have 7um on TS so the scale factor increased...

We run 20 steps of TS correction. After that we have 250nm of focus that oscillates

We repeat the analysis without disturb:

ARGOS - FLAO test

14:15: we build a mixed FLAO - ARGOS REC merging the FLAO REC 20130916_221257 and the ARGOS REC 150modes_ryb_1kHz_TTrm_CoG.

REC: 20141107_212511 mixed ARGOS - FLAO

we close the TT loop with FLAO without disturb and gain=+0.4, ARGOS corrects for 36modes with gain=-0.01.

To enable slopes from FLAO we have to go on varToolGUI and set the following parameter

slopeCompCtrl.FASTLINK.ENABLE.REQ = 1

We load disturb equivalent to 1.2" and we close the loop again

ARGOS - FLAO - TS test

same test as before, we add 10um of focus moving FLAO Z stage:
