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

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

7. If this is the first time in 24 (is this correct?) or more hours that the D4 has been turned on, the X-ray tube now needs to be conditioned. Go to the Maintenance section under Tube Conditioning for instructions and log the date of tube conditioning in the XRD maintenance log in XRD's Lab Notebook on confluence.
Shutting Down Bruker D4 XRD
The Bruker D4 can be kept on when not in use. However during extended periods such as Tie-ups or if there is not someone to check on the instrument it can be shut down. The haskris can also remain on, or it can be turned off if no one is able to monitor it. If the Bruker D4 is on the Haskris must be on as well.
1. Turn the X-Ray generator off by turning the key counterclockwise.
2. Push the Red button.
3. Turn off the High Voltage button B as shown in Figure 2.
4. Turn off the main CPU button A as shown in Figure 2.
