The instruments in the lab need to be turned on in this order: (1) HASKRIS and (2) D4. The HASKRIS cools the water supplied to the D4 to prevent the X-ray tube from overheating. Turning the D4 on prematurely will damage the X-ray tube.
Procedure for Turning on Instruments
Turning on Haskris and Bruker D4
...
Open the XRD Commander program using the icon on the toolbar. Figure 23 is the initial window. Be sure you are in the Adjust tab (btm left, 23A).
Figure 23: XRD Commander main window.(A) Initialize Sample Changer button(B) Initialize Driver Request checkmarks (C) Jobs tab
First initialize the Sample Changer by clicking on Init SC (Figure 23A). The checkmarks (Figure 23B) indicate the drives that will be initialized. Check the "Div. Slit" box before initializing; the program typically remembers the Theta, 2Theta, and Phi drives. Successfully initialized drives will turn blue. If one or more stay red, you can try restarting the program and reinitializing, and/or turning off the D4 and restarting the instrument. If that does not work, close XRD Commander and open D4 Tools. D4 Tools and XRD Commander cannot be open at the same time. Go to the drives that will not initialize and click the "Adjust" button. Then close D4 Tools and reopen XRD Commander. The "Adjust" command can also initialize the drives. The diffractometer's sample-changer drives will adjust inside the instrument. If you hear a crash or the program gives an error, see the procedure for readjusting the sample handler in the Bruker manual. This is a lengthy process.
Entering Sample info into the Commander
Click on the Jobs tab (Figure 23C). On the Jobs screen, click on "Create Jobs".
