Sample positioning stage
Brazilian Synchrotron Light Source, Campinas, Brazil
A sample positioning stage which has been designed and realized that has very demanding requirements for stability (< 5 nanometer) while scanning the sample and keeping it at cryogenic temperatures.
At the Brazilian Synchrotron Light Laboratory (LNLS) a multi-technique X-ray microscope has been developed that can be used for simultaneous multiple nanoscale X-ray techniques in 2D and 3D.
For the proper functioning of this microscope, a new in-vacuum cryogenic sample stage (x, y, z) with nanometer-level (< 5nm) performance has been developed to address the positioning and thermal requirements for the sample.
