First results in the IR and THz spectral range at the Metrology Light Source

摘要

In summary, the project Metrology Light Source is well under way. The MLS as one of the few low-energy storage rings worldwide is expected to be an ideal IR synchrotron radiation source. The parameters of the MLS, especially the electron beam current and the electron energy, can be varied in a wide range in order to create measurement conditions that are tailor-made for specific measurement tasks. A special mode of operation allows the production of coherent synchrotron radiation and thus the production of THz/FIR radiation with enhanced intensity making the MLS an promising radiation source for THz metrology. A dedicated beamline provides this radiation at the experiments. PTB will continue to optimize the MLS as an IR and THz radiation source in a systematic and quantitative way based on well characterized optical components and calibrated detectors. Radiometry, spectroscopy and microspectroscopy will be performed after setting up dedicated experimental stations and typical instrumentation (FTIR spectrometers, microscopes, bolometers) at the beamlines.
