Adjusting the monochromator
In the R-XAS Series, the section that containing the monochromator-crystal set is referred to as
the “monochromator,” and control is exerted on its three axes;
ω
, tilt, and Z. The
ω
-axis represents
the axis of rotation in the direction of the diffraction plane, tilt is the axis of elevation orthogonal to
ω
, and Z is the longitudinal axis. Adjust the monochromator precisely so that the X-rays emitted
from the X-ray generator are led to the sample section.

Specify the scanning range of each axis in “start” and “end.” Next, specify the step width and
measurement time at each point and select, using the radio button, the output of the detector, I
0
or I,
to be displayed on the screen. The detector selected in that operation must have been initialized. In
cases in which no signal is displayed despite the fact that scanning has been performed, or an error
occurs, initialize the detector.
