Aux FW remotizzata

Vecchio PC di Alfio collegato via USB alla FW e poi via VNC si controlla con l'Hyperterm.

Tutto descritto su TowerConfigurations.

Rimozione readout speed lenti

I readout speed piu' lenti (150 kpix/sec ed equivalenti agli altri binning) sono stati rimossi dalla configurazione del ccd, in modo che non vengano piu' selezionati quando si imposta un frame rate.

test readout speed PRIMA:

Bin: 1 - Framerate 990 Hz - RON (ADU): 18.41 - RON (e-): 9.20 (estimated)
Bin: 2 - Framerate 990 Hz - RON (ADU): 13.32 - RON (e-): 6.66 (estimated)
Bin: 2 - Framerate 625 Hz - RON (ADU): 9.27 - RON (e-): 4.64 (estimated)
Bin: 2 - Framerate 400 Hz - RON (ADU): 9.01 - RON (e-): 4.51 (estimated)
Bin: 3 - Framerate 200 Hz - RON (ADU): 12.12 - RON (e-): 6.06 (estimated)
Bin: 4 - Framerate 300 Hz - RON (ADU): 13.02 - RON (e-): 6.51 (estimated)
Bin: 4 - Framerate 200 Hz - RON (ADU): 12.77 - RON (e-): 6.39 (estimated)
Bin: 4 - Framerate 105 Hz - RON (ADU): 12.95 - RON (e-): 6.47 (estimated)

test readout speed DOPO:

Bin: 1 - Framerate 990 Hz (2500 kpix/sec) - RON (ADU): 18.52 - RON (e-): 9.26 (estimated)
Bin: 2 - Framerate 990 Hz ( 800 kpix/sec) - RON (ADU): 21.78 - RON (e-): 10.89 (estimated)
Bin: 2 - Framerate 625 Hz ( 380 kpix/sec) - RON (ADU): 13.50 - RON (e-): 6.75 (estimated)
Bin: 2 - Framerate 400 Hz ( 380 kpix/sec) - RON (ADU): 13.52 - RON (e-): 6.76 (estimated)
Bin: 3 - Framerate 200 Hz ( 380 kpix/sec) - RON (ADU): 14.11 - RON (e-): 7.05 (estimated)
Bin: 4 - Framerate 300 Hz ( 335 kpix/sec) - RON (ADU): 14.86 - RON (e-): 7.43 (estimated)
Bin: 4 - Framerate 200 Hz ( 335 kpix/sec) - RON (ADU): 14.87 - RON (e-): 7.44 (estimated)
Bin: 4 - Framerate 105 Hz ( 335 kpix/sec) - RON (ADU): 14.96 - RON (e-): 7.48 (estimated)

Era meglio prima! Ma i problemi piu' grossi, ad esempio i 10 e- a bin2, non sembrano dipendere dall'eliminazione del 150 kpix...

Il valore della lampada per ottenere un certo flusso non sembra molto riproducibile, prima di pranzo facevamo il flusso giusto con la pos=2, mentre ora dobbiamo farlo con la pos1 Lamp=117

Facciamo autofocus per Pos1



PROBLEMA DI PRODUZIONE FRAMES BCU CCD39

Ci accorgiamo che la diagnostica ha 2 frames per ogni frame che il CCD39 dovrebbe produrre.

Se si imposta 200Hz sul 39 il loop va a 400Hz.

Spento e riacceso LJ39.

Lo fa a Bin3 ma anche a bin2... a bin1 va bene.

Torniamo a bin2 e lo fa di nuovo.

Vediamo i frames salvati e sembrano frames veri e tutti diversi -> e' il ccd39 che e' impazzito?

Alfio ripristina la selezione dei ROSpeed come erano prima e torniamo alla normalita'


Riproviamo col punto a bin 3

TEST LOOP

Facciamo un loop chiuso di test ad alti fotoni per vedere se la causa delle basse performance รจ davvero il RON. Teniamo il resto uguale (bin3, etc).
