8:20: SX CalUnit is in

Hexapod set ack to December position: [4.98; 0.39; -0.61; 211; -100], and FLAO board to: [-73.8; -45.9; 45.0].

PBL with crane give us no telescope access for the whole morning.

LgswUnitSx FoV measurement

14:00: back to SX CalUnit. We try to measure LGSW FoV using the scan with FLAO stages:
  1. setup everything
  2. close loop on LGSW only
  3. align FLAO board on on-axis source
  4. open LGSW loop and close on FLAO
  5. measure LGSW FoV moving FLAO stages

LGSW pupils are out, we update the default position for CalUnit:

Pupil X Y
Blue 330 411
Yellow 371 438
Red 525 412
and we save a new pupil target: 20160308_213346

HEXA 5.03 0.68 -0.75 115 -86
Board -74.6 -52.2 45.0    
We always forgot that all the time you acquire the LGSs from the AARB GUI we must read the hexapod position on the TCS GUI and set it back, otherwise the AdSec offload doesn't work!

Scan w/ board: 1" in 3 steps. It doesn't work! We need a movement pattern that minimizes the jumps.

So we turn back to the scan w/ hexapod. Range= +/-10" of Rx and Ry in 11 steps:

20160308_224400_fov_centers.png

Then we switch off the Pockels cells and we repeat the same measurement:

20160308_225500_fov_centers_noPockel.png

It seems very bad, better to keep the PC on!

We move the hexapod to match the best center position for the Blue pupil: [+0.5; +4.0]" so hexapod Rx, Ry= [115.5; -84.5]. Then we try another scan with +/-5" and 3 steps, we also acquire snapshots:

But the result is too coarse, we try again with +/-5" and 11 steps:

We are more convinced that the best center for the FoV is guessed from the larger scan (>10"). So we put the hexapod in the position that matches the 3 FoV centers and we close the jitter loop (having init position = 'zero') to measure the init positions:

Pupil [Rx; Ry] PI
Blue [115.0; -88.5] [-1.25; 3.15]
Yellow [112.5; -88.3] [-2.20; 0.40]
Red [110.5; -88.5] [-4.50; 0.40]

These values are saved in a new jitter initial position: 20160309_000200

then we try another scan from [115.0; -88.5] with +/-10" and 11 steps keeping the jitter loop closed. BAD IDEA! when the spot is out of the FoV the piezos go banana and never get back!

Last scan with +/-20" and 11 steps:
