Mounting Plates

There are two geometries possible for mounting the sample on the diffractometer:

• horizontal geometry: the sample holder is mounted on the chi-stage of the HUBER tower. In this case, the distance from the mounting surface to the sphere of confusion of the diffractometer (height of the sample holder) is 170mm. The structure of the Huber tower which can carry heavy loads (vacuum chamber) is the following : a 5203.2 circle segment (chi-stage : ±20° range) is mounted on a 5103.2 Z table (±20mm range) mounted on a 5102.2 XY table (±15mm range).
• vertical geometry: the sample holder is mounted on the x-stage of the Kappa circle. In this case, the distance from the mounting surface to the sphere of confusion of the diffractometer (height of the sample holder) is 130mm. The structure of the Kappa circle is the following : a 5102.2 XY table (±15mm range) is mounted on a specially designed circle segment (phi-stage) and Z table (±10mm range).

More detailed informations can be found on the Huber website.

Sample holders are available for both geometries but users can provide their own sample holders specially designed to suit the hole patterns of the mounting plates (chi-stage or x-stage).
