Test of DX LGSW with CalUnit and rigid secondary (afternoon)

Problems with Arbitrator

• Restart not possible in situation of shutdown of LAS and powering_up of LGSW. During transition state no command accepted on LGSW side and timed out on Arbitrator side.
• Previous situation happened due to blocking of Arbitrator (graying out). This happened several times.

After setting all up red laser could be found left of yellow.With following parameters the beams could be caught (very much trial and error and not representative)

Right PSF 2ndary

Setup Lasers for heater test (evening)

With setting up the lasers for the heater test Laser3 on DX was not working properly. After closing and opening internal shutter with help of ranger (SOFTWARE_KEY_POSITION) issue was resolved.

LgswUnitSx calibration with AdSec

PBL with AdSec start. The ADSEC.L.OFLMODES variable is set as a string at startup while it should be real. A workaround is to delete it and to restart the fast diagnostic service.

We start acquiring new IMs having fixed the slope computing bug.

Pupil motors are:

Beam	X	Y
Blue	325	421
Yellow	376	438
Red	487	432

150	20151211_160100	20151211_161154	20151211_161400

We find out that we are acquiring IMs at 1kHz, we reduce loop speed at 610Hz:

Beam	X	Y
Blue	325	411
Yellow	376	438
Red	487	432

# modes	IM REC	IM	LGSW REC
150	20151211_161400	20151211_161933	20151211_162200

We define new modal amplitudes having normalized all slopes rms to 0.05: modal amplitude: 20151211_162400_rms0.05

On this modal amplitude we define several modal histories:

# modes	Modal history
150	20151211_163400_150modes
50	20151211_163500_50modes
10	20151211_163600_10modes

We recenter again pupils and acquire a new jitter initial position: 20151211_164257. There is no way to have all the 3 pupils unvignetted

# modes	IM REC	IM	LGSW REC
150	20151211_162200	20151211_164434	20151211_164600

We see a sort of ear at the lower right edge of the blue pupil. It is much more visible in mode 1 Y slopes.

• Modal amplitude: 20151211_164800_rms0.10
• Modal amplitude: 20151211_164900_rms0.20

From these 2 modal amplitudes we create histories:

# modes	Modal amplitude	Modal history
150	20151211_164800_rms0.10.fits	20151211_165000_150modes
50		20151211_165100_50modes
10		20151211_165200_10modes

Using MH 20151211_165000_150modes:

# modes	IM REC	IM	LGSW REC
150	20151211_164600	20151211_165247	20151211_165300
150	20151211_164600	20151211_165912	ears are visible in the TT modes

We try to increase the TT gain during IM acquisition from 0.05 to 0.2:

# modes	IM REC	IM	LGSW REC
150	20151211_164600	20151211_170128	ears...

We fear that the pupil can be misaligned. Up to now we aligned them by putting 0 flux on the central subaperture.

Yellow	366	448
Red	497	432

The last LGSW only combined rec it is not working fine. The lower right edge of the pupils is always quite instable.

We close the loop on 150 modes, LGSW only. The best combination of gains seems to be [0.5, 0.4, 0.4]. We load 1.0" disturb:

Now we start the FLAO, we feed it with the pennina. We center the pyramid board to -71.95, -46.7, 35.0 mm. Pupil rerotator is at 88.4deg, instrument rotator at 340.98deg. Pyr configured as BIN2, 975Hz.

We build combined recs for FLAO:

REC TAG	LGSW REC	FLAO REC	COMBO REC
TCoG48, BIN2	20151211_183400	20151202_213530	20151211_202800
TCoG48, BIN4		20151204_191745	20151211_202900

14:00: we check the best focus for the N3.75 camera. Z stage is at 50mm.

Now we close on LGSW only. Z stage is at 35mm for the best focus position on LGSW...
