Cooling samples to liquid nitrogen temperatures can delay radiation damage, but must be done in a vacuum environment to prevent rapid formation of ice on the sample. The Canadian Light Source (CLS) has constructed a Cryo-STXM, which can maintain sample temperatures at 100 K in an ultra-high vacuum environment and rotate the samples in the beam to collect tomographic data sets. This presentation will discuss the mechanical engineering aspects of the development of this Cryo-STXM including the finite element analysis (FEA) for stresses and vibrations, and present the performance parameters being achieved by the instrument.
