Description

The goniometer is a self-contained unit for mounting in the X-
ray apparatus and is included in the scope of supply of the X-
ray apparatus (554 811). It is equipped with two independently
controllable stepping motors which move the sensor and target
arms. The motion is defined using the keys in the control panel
of the X-ray apparatus and initiated manually with the ADJUST
knob or automatically with the SCAN key (see instruction sheet
of the X-ray apparatus).
The target stage can accommodate e.g. the LiF crystal for
Bragg reflection (554 77), the NaCl crystal for Bragg reflection
(554 78), the aluminum scattering body from the Compton ac-
cessory X-ray (554 836) or other samples.
The entire goniometer unit can be shifted within the experiment
chamber. The length of the sensor arm is variable, so that the
angular resolution can be altered for the slit of the sensor.
Note
The goniometer is positioned solely by means of electric
stepper motors:
• Do not block the target arm and sensor arm of the
goniometer and do not use force to move them.
