This table lists the most important reflections with line positions in 2 for Cu radiation
(Cu
K1
= 0.154060 nm). The certified reference material to be used is based on Bruker AXS’s inhouse
corundum standard reference material.

There is a level for instrument verification which is called daily check. This performance verification
level covers the functionality of all relevant components of the diffraction system under investigation.
The daily check routine is a procedure to routinely check with the corundum standard that the
instrument is operating within specified limits.
For D2 PHASER systems with Cu-radiation, we recommend the following settings:
- Sample Bruker AXS’s corundum standard reference material
- Generator 30kV, 10mA
- Divergence slit 1.0mm (0.6°)
- Soller slit module primary: 2.5°, secondary: 2.5°
- Antiscatter screen no
- Filter Ni
- Receiving slit 0.2mm for scintillation counter systems
- LYNXEYE detector 5° detector opening and standard 0.5% Ni-filter
- Rotation 15rpm is recommended
Configuration and settings of primary section
The standard Soller slit module is 2.5°. Its position is in the primary slit holder system as shown in fig.
18. The 2.5° Soller slit module may be replaced with the 4° or 1.5° unit ((b) in fig. 19) if required. In this
case remove the cover of the primary slit holder system: Move 2 to 60° and open cover of the
primary slit holder system by removing the screws ((d) fig. 6). Access to these screws is possible
through the front door.
Insert a primary slit module into the slit holder system as shown in fig. 33. Preferably use a 1mm slit
module ((d) in fig. 19) for high intensity and optimum resolution. Pay attention to insert it in the correct
orientation as shown in fig. 31, 33.
Configuration and settings of sample section
Prepare your sample into a suitable sample holder which is offered for D2 PHASER diffractometer
systems. A measurement with the Bruker AXS’s inhouse corundum standard reference sample is
