  1. Flip the "ON" switch (Figure 4C) to the HASKRIS and the water in the tank will begin to cool. The water temperature needs to reach 69°F (Figure 4A). The Haskris temperature can range between 65°F to 69°F (18-21ºC). Ensure all water valves to/from Haskris are open.

  2. Flip the "ON" switch (Figure 5A) on the side of the Bruker D4 XRD.
    1. The solid green "Low Voltage Ready" light (Figure 5F) turns on.
    2. You will hear several beeps and the "System Activity" light (Figure 5D) will start flashing green.
  3. Press the "High Voltage Enable" button (Figure 5B).
    1. The "System Activity" light turns green.
    2. An orange "High Voltage Ready" (Figure 5E) light will turn on.

4.      Go to the front of the machine and press the green circular button (Figure 6). This enables the mains power and activates the sample handler.

  1. Unless the sample material is very small (see Sample Slurry/Smear Slide Mounting for Small Sample Amounts),  select the appropriate sample holder (Figure 8A).
  2. Label the sample holder with a unique identifier to keep the samples organized (e.g., text ID or 14H2 77-78)
  3. Place enough powder from the labeled sample bottle to fill an empty sample holder (Figure 8B). Gently press the powder flush with the sample holder using a glass slide (Figure 8C). Roll the glass slide over the powder to fill any gaps in material and smooth the surface of the powder (Figure 8D). The surface of the powder must be smooth. Remove excess powder from the sample holder edges with a brush or a Kimwipe (Figure 8E) and carefully place the holder in the D4 sample magazine .

Open the XRD Commander program using the icon on the desktop or toolbar. Figure 11 is the initial window. Be sure you are in the 'Adjust' tab (bottom left, Figure 11).

The checkmarks (Figure 11A) indicate the drives that will be initialized. Check all boxes with values before initializing: Theta, 2Theta, Div. Slit, Phi. Click on Init SC to initialize the Sample Changer (Figure 11B). The program then 'locates' all the mechanical drives in the D4. It typically remembers the Theta, 2Theta, and Phi drives but the Divergence Slit sometimes does not initialize. That should not be an issue for scanning samples as our Div. Slit is not mechanical, however if the software won't scan a sample because one or more of the drives did not initialize (successfully initialized drives will turn blue, Figure 11C) you can try restarting the program and reinitializing, and/or turning off the D4 and the XRD Commander software and restarting the instrument then the XRD Commander software and repeating the steps above. If that does not work, close XRD Commander and open D4 Tools from the desktop. Note D4 Tools and XRD Commander cannot be open at the same time.

In the XRD Commander, click on the 'Jobs' tab next to the 'Adjust' tab (see Figure 11C11) . On the 'Jobs' screen, click on the "Create Jobs" icon in the toolbar (Figure 15A).

...

When all fields have been filled in, click on the "Start" button on the bottom left corner of the screen (Figure 15H). The program will hesitate for a moment and then load the first sample into the measurement position and a second sample into the sample changer. The program will automatically run the samples sequentially. The measurement is finished when it is displayed 'Finished' in the "Status" column of the 'Jobs' tab. If there is an error while scanning the program will stop and notify the user of the error. You can try restarting the software and/or the D4. A sample handler crash may require an experienced D4 XRD tech or you may need to contact Bruker. With the D4 off you can manually move the Z-drive and the sample swing loader, just be aware that the moveable drives are set up to avoid each other during the sample loading sequence, if you move a drive it may cause a crash on start up.

The D4 Endeavor has several safety issues that should be reviewed. Please see the Bruker Manual D4 Endeavor XRay Diffractometer – Introductory User Manual for the list of precautions.

Run the NIST 1976 standard (see Quality Assurance/Quality Control) and import the values into the instrument verification spreadsheet. Perform a Zi correction if needed. Calibration of the VANTEC-1 detector may be required. See the detector manual.
