Sample positioning stage
Brazilian Synchrotron Light Laboratory, Campinas, São Paulo, Brazil
A sample positioning stage with has been designed and realized that has very demanding requirements for stability (nanometers) 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 with nanometer-level performance has been developed to address the positioning and thermal requirements for the sample.
