Fast CCD

The fast CCD camera produces a 480x480 pixel image, arranged as 500x576 with empty rows and columns (info pixels)

  • To get the trimmed 480x480 image: 
    Height:
500 rows   = 6 + 240 + 7 + 240 + 7
       Dark A: 6   Rows 0-5
     Data Top: 240 Rows 6-245
       Dark B: 7   Rows 246-252
  Data Bottom: 240 Rows 253-492
       Dark C: 7   Rows 493-249

Width (in 16-bit pixels):
576 pixels = 12 * 48 outputs
           Top: (10 image pixels followed by 2 info pixels) * 48 outputs
        Bottom: (2 info pixels followed by 10 image pixels) * 48 outputs
  • Also be aware that the 16-bit pixels are read out via two cables, 8-bits each. To get
    the right format, read out as 16-bit integers instead of 8-bits. Straight-forward for myana, but with pyana
    you need to be aware of this and convert the output:
    myana/C++
    int status;
status = getFrameValue(fccdDet, fccdWidth, fccdHeight, fccdImage);
    pyana/python
    data = evt.getFrameValue("SxrBeamline-0|Fccd-0").data()
data.dtype = np.uint16
