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, select the appropriate sample holder (see Sample Slurry/Smear Slide Mounting for Small Sample Amounts).
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. Gently press the powder flush with the sample holder using a glass slide. Roll the glass slide over the powder to fill any gaps in material and smooth the surface of the powder. The surface of the powder must be smooth. Remove excess powder from the sample holder edges and carefully place the holder in the D4 sample magazine (Figure 8).

The window shown in Figure 15 will pop up. Fill in the 'Position', 'Sample ID', 'Parameter File', and 'Raw File' columns.

********To keep updating from here******

• Position (Figure 15B): This is the position of the sample in the loading magazine in the D4, from A1–A6 to K1–K6. Enter the position manually.
• Sample ID (Figure 15C): Scan in the label for your sample here. The only format that MegaUploadaTron (MUT) will recognize is Site_Core_Top offset_Bottom offset_TextID (e.g., U1481A_32R4_91_92_QRND8021751). The barcode scanner in the XRD X-Ray Laboratory is programmed to scan in this exact format including underscores. For special treatments such as clay, glycol or heat treated, you must include the treatment in the file name. Add the treatment in the following way U1565A_1R1_3_4_clay_WDGE11053881.
• Parameter File: This is a premade DQL file that sets the conditions under which samples will be scanned. Access the file by clicking on the "Open Directory" button (Figure 29D15E) This directs you to the Control Panel. Follow the path "Local Disk C: > DIFFDAT1. This has a list of all the parameter files from previous expeditions. Select the one that is best suited for your scan parameters.
• Raw File: Sets the location where the results will be saved. Set the location by clicking on the three dots at the end of the cell. Then follow the path "Local Disk C: > DATA > IN". Copy the sample ID into the "Open" line in the window. The sample ID and the name entered into the "IN" Folder must be identical or else the information will not be stored correctly.

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.
