Appendix C: Thermal Expansion of the Sample Holder

Appendix C: Thermal Expansion of the Sample
Holder
Due to the thermal expansion of the used materials
the height of the sample holder expands with in-
creasing temperature which makes regular realign-
ments during high- temperature XRD investigations
necessary.
The tables and diagrams below show measure-
ments of vertical expansion of the rigid sample hold-
er in vacuum and air. The indicated values are
comparable for the rigid sample holder and for the
sample spinner and are supposed to give a rough
idea about the magnitude of vertical expansion.
