First commissioning results in the IR/THz range at the electron storage ring Metrology Light Source

The Physikalisch-Technische Bundesanstalt (PTB) has set up a low-energy electron storage ring in Berlin-Adlershof in close cooperation with the BESSY GmbH. The Metrology Light Source (MLS) is the first machine designed and prepared for a special machine optics mode (low-alpha operation mode) based on an octupole correction scheme, for the production of short bunches and coherent synchrotron radiation (CSR) in the FIR/THz spectral range. In our contribution we present first commissioning results which clearly indicate that the MLS in combination with dedicated beamlines offers intense, stable, and well focussed THz radiation.
