7. Z: Use “@”
8. Aux: Use “@” (this is the camera zoom)
• Scan Axis #: Coupled
• Frame width: 20-30 (depending on the amount of overlap desired on integration)
• Mode: STEP
• □ Rotate Sample: Typically not used for powder diffraction
• Sample Osc: None
• Amplitude: 0.00 (This is only relevant if you are oscillating your sample)
• Frame Header Information: Change as necessary (only seen in GADDS)
• Filename generation: Specific to the sample and project
• Max display counts: 15
• Realtime Display
• Pre-clear
• □ Capture video image
• □ Auto Z align
e. Once the parameters are setup correctly, press the OK button to start the scan.
f. The data will be automatically saved as a .GFRM file in the project folder that was created in an
earlier step.
g. The last frame collected will be shown in GADDS when the measurement is finished.
i. To navigate to different Frames with in a Run, press “CTRL” + “→” or “CTRL” + “←”
h. Integrate the data create a one-dimensional scan for evaluation in EVA:
i. Go to the frame of interest, then:
1. →Peak, →Integrate, →Chi, →enter
2. Select the range you are interested in
3. Save the file in the folder of interest for further analysis using EVA. →Peak,
→Integrate, →Chi, click OK
4. Use 1, 2, 3, 4 to change the 2θ range and Chi range for integration
a. If you are planning to merge multiple frames of different 2θ ranges, it is
important to note the beginning and ending values of 2θ.
5. Integrate the next frame in the series, → “CTRL” + “→” or “”
a. Then repeat the above steps
b. Make sure you have at least 0.1 degree of overlap on the beginning and
ending 2θ values, otherwise your scans will not merge together in EVA.
