SMIS
SMIS is an infrared spectromicroscopy beamline that delivers high-brilliance radiation in the mid and far-IR spectral range. The synchrotron beam is split to operate two endstations in parallel. The beamline is dedicated to multiscale spectromicroscopy, allowing up to ~20 nm spatial resolution and up to several cm sample size combining several instruments. We offer a variety of environmental conditions including pressure, temperature, atmosphere and polarization control.

SMIS, in collaboration with multiple research groups is participating in the development of Quasar, an open source project, a collection of data analysis toolboxes extending the Orange suite. We empower researchers from a variety of fields to gain better insight into their data through interactive data visualization, powerful machine learning methods and combining different datasets in easy to understand visual workflows.
Potential users can download the software from the Quasar website and interested developers can contribute to the repositories of the Quasars GitHub organization.
