  The Helmholtz Zentrum Berlin and the Max Planck Society are going to build a new dedicated X-ray beam line at the synchrotron source light source BESSY II which will be used for analyzing materials for renewable energy generation. The new large scale project has been dubbed EMIL. In this document we present the modifications to the machine optics and to what extent these changes affect the performance of BESSY II.

  At the Metrology Light Source (MLS) * of the Physikalisch-Technische Bundesanstalt (PTB) the bunch length can be varied by more than two orders of magnitude **. The bunch length manipulation is achieved by varying different machine parameters, such as rf-voltage amplitude up to 500 kV and the momentum compaction factor over three orders of magnitude. The subject of this article is the measurement of THz bursting thresholds at the MLS for different bunch lengths.
