ADX CCD control software

The Quantum 1 and Quantum 4 detectors are run by the ADX software.

• to start the package: start_ccd
• a menu window "ADX" appears: SETUP / STOP / DISPLAY / PROCESS / EXIT
• SETUP:       manual control (see below) / snapshot (see below) / (irrelevant items)
• STOP:         immediately / after current image (self-explanatory)
• DISPLAY:  status (opens "ADX-Status" window) / image (display current or some previous image)
• PROCESS:  process crystallography data (irrelevant for SAXS)
• EXIT
• manual control
• operate shutter manually for line-up: SETUP > manual control > shutter > open/close
• snapshot
• a new window "ADX snapshot" appears:
• set directory to your user directory
• set filename (it has to end in nnn, e.g. test_002.img)
• set distance sample-detector
• set Df to 0
• choose an exposure time in seconds (1 sec and up)
• ADC: slow (default)
• Collect new dark current
• take at least one dark image for each new exposure time
• bug: you have to click first on "no", then on "yes" for the program to accept the click
• Dezinger: no (interesting for exposures longer than 30 sec)
• take snap
• check on the "ADX-status" window whether the shutter opens
• the image will appear in the image window, after the detector is read out (about 10sec)
• simple image handling with "Adxv Control":
• scaling is only linear; min and max rage can be chosen in the image control window
• color schemes: grey scale and various color schemes (heat, rainbow) can be chosen
• pixel numbers: by positioning the mouse on a spot in the image, pixel number and intensity are displayed
• slices: if you drag the mouse across the image, a slice will be shown in a separate graphics window
• calibration
• click "Edit > Settings" to open the manual calibration window
• check values for distance, pixel size, and wave length
• determine the beam center from the pixel coordinates in the image window
• when you click on a point in the image window, the correct d-spacing of the feature will be displayed
• more sophisticated image handling can be performed with "fit2d" (see below) or "TVX" (not yet available).
