Title: CCD

CCD
  • Finger lakes Instrumentation www.fli-cam.com
  • Camera Model MaxCam CM7
  • CCD Array KAF-401E, 6.9x4.6mm, 768x512
  • Readout one row 2sec, full frame12 sec
  • SDK for C provided by manufacturer
  • mitbbr11.lns.mit.edu
  • dmatter account
  • ROOT classes to run camera, analyze data
  • - write out FITS, PNG (trivial, not yet done)
  • - default ROOT file (events containing
    time-stamp camera setup, image, add chamber
    setup?)

2
Bias Frame (1/3)
Opens a root file, Initializes a camera (one for
now)
MaxCamTest exper // Setup camera
exper.ccd()-setExposureTime(0) // exposure in
msec //exper.ccd()-setHBin(16) // x binning
//exper.ccd()-setVBin(16) // y binning
exper.ccd()-setDarkFrame() // or setNormalFrame
(default) // take few bias frames for (int
i0 iexper.end()
Takes an image, saves TH2F, time-stamp, camera
configuration in an event tree
3
Bias Frame (2/3)
Opens a root file on a remote server (xrootd)
MaxCamRead analysis analysis new
MaxCamRead(root//mitbbr11.lns.mit.edu//data/bias
Frames.root) cout analysis-NEvents() getEvent(0
) // access 1st event analysis-setROI( 600,
650, 400, 450) // set analysis
ROI analysis-image()-Draw("colz") // access
image analysis-dtime()-Print() // access
time-stamp analysis-ccd()-CCDTemp // access
CCD configuration
Access to event data
