AU-IR on ASTRID2
The AU-IR beam line was commissioned on ASTRID2 in 2014 and is equipped with a Vertex 70v FTIR spectrometer. The beam line takes full advantage of the excellent low energy radiation from the low energy storage ring, using edge radiation from a bending magnet of ASTRID2. The high brightness yields a flux which is comparable to most of the large light sources in the world. The lack of high energy radiation from ASTRID2 actually makes the design much simpler and cheaper. The IR beamline is dedicated to studies in biology and other condensed materials. The higher brightness of the light source will be highly suitable for small size particles and has relatively much higher flux when going into the far infrared range compared to larger light sources. The current setup is focused on working in the mid IR range. Further upgrades to the beam line are planned, including replacement of the ZnSe window to allow measurement into the far IR and also some changes to the optics in the FTIR spectrometer for a smaller spot size.
