H17:00 J.Hill fa test di tracking non siderale con il telescopio a cupola chiusa

H18:00 Test and debug di LUCI presets

H18:30 Walter pupil check on N30

H19.45 Acquisition of images for calibration estimation routine

We set the lamp to a lower flux to avoid LUCI2 saturation (500ph/subap --> 200ph/subap).
LUCI2 gives us a single fullframe instead of a cube of 20 subframes... :-(
LUCI2 was set in simulation mode, now is working ! smile

Autofocus con Zstag, NCPA ON. Conferma Zstage = 49.3mm

Crosscheck facendo scan del fuoco con gli Z nelle NCPA con 5nm di risoluzione. Conferma che il fuoco e' corretto.

H00:05 del 27 - Test Filtri IIR

Primi check negativi

H00:45 Test applicazione NCPA stimate con OPRA

Primi check negativi

H00:55 Scan NCPA fino a Z21

Lo scan fino a di Z12 Z13 Z14 Z22 identifica solo 3nm di Z12, quindi in pratica lascia tutto inalterato.

H01:20 Scan NCPA @ROT=150deg

Z5=+40, Z6=-15, Z7=0

Applicando lo Z8 il loop va in skip frame. Mettiamo a 0.05 il guadagno per i modi >50. Il loop a 400 modi puo' avere piu' problemi del normale a causa del vignettamento della pupilla dato dalla pennina.

Z8=10, Z9=-7.5, Z10=+5, Z11=-10 -> ncpaLuci150deg

H04:30 Test filtri IIR

Test di solo fuoco (2 poli, 2 zeri - parametro di stabilità distanza da [-1,0]=0.35 ): riuscito!
Test di 10 modi (4 modi con 2 poli, 2 zeri, altri 6 con integratore):: riuscito!
Acquisizione dati: TN113940

IIR 20150127_113940_resmodes_jitter.PNGIIR 20150127_113940_modes_jitter.PNG

Prendiamo un TN con l'integratore 50 modi per confrontare il residuo di Tip-Tilt: TN114247 - 114301

INT_20150127_114247_resmodes_jitter.PNGINT_20150127_114247_modes_jitter.PNG

I residui a 20Hz sono molto minori, ma apparentemente ha un overshoot a 50Hz! NOTA: Non abbiamo verificato che la compensazione dell'optical gain fosse attiva.

Seconda prova con filtro IIR con 4 poli, 4 zeri (parametro di stabilità distanza da [-1,0]=0.275). Si vede chiaramente un'oscillazione del Tip-Tilt, ma il loop non diverge.

Nota per la prossima volta: maggiore stabilità (parametro di stabilità distanza da [-1,0]>0.275) e maggiore reiezione a 50Hz a costo di una minore a 20Hz.
