Flicam Detector

The Flicam  CCD detector has a pixel size of 69.78 mm and a total array of 1024 x 1024  pixels. the active area is directly at the front plate of the detector.

The Flicam detector can be run from the spec interface. To start the real time window, which auto-updates after each exposure, type autoview from the specuser prompt at g1hutch. Start each time with a short exposure time after you opened the garage door to make sure the beamstop is in place.

The commands are as follows:

• ccd_on:    switch to ccd mode

• ccd_off:    turns the ccd mode off. Do this for line-up measurements, where you do dscan or ascans

• dark <n>: takes two dark images, both for <n> seconds, dezingers them and keeps the dezingered image

• corr <m> <n>: takes <m> images for <n> seconds, subtracts for each the background, which has been taken with dark <n> and corrects for intensity and distortion. If <m> = 1, the corrected file will be stored under <filename>_<runnumber>_c.tif. If <m> is alrger then 1, all the images will be dezingered and  corrected like described above. The file will be stored under <filename>_<runnumber>_cz.tif. The single raw images will be stored under  <filename>_<runnumber>_<scannumber>.tif.

 

 

You can load images into the ADSC- software from the Quantum-one detector or into Fit2d to view your data. 

The interlock system works in two steps:

If there is no vacuum and no waterflow the thermoelectric cooler (TE) will have no power. After making sure  that both conditions are fullfilled (vaccum is down and waterflow diode is on), you can reset the interlock to enable power to the TE. The CCD can  only be enabled after the TE is on and the Temperature should have  cooled down to 40° C.
