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

Bias Frame (2/3)
Opens a root file on a remote server (xrootd)
