| Zusammenfassung | There is an increasing interest in Pico and sub-Pico second long bunches in electron storage rings [1]. These bunches can be achieved by tuning the ring into a dedicated ’low-α’ optics [2]. A key parameter to control the bunch length is the momentum compaction factor α. The Metrology Light Source (MLS) [3] of the PTB (Physikalisch-Technische Bundesanstalt, the German national metrology institute) is the first storage ring, which applies a new method for reliable tuning of the low-α optics, based on a sextupole and octupole correction scheme [4]. With this method, α can be varied by more than a factor of 1000 and stable beam storage at low-α values is achieved. We present here the first operating results of the low-α optics. Characterizations of related THz radiation at MLS are presented in [5]. [1] G. Wuestefeld, EPAC 2008, Genoa (Italy), p.26. [2] J. Feikes et al., EPAC 2004, Lucerne (Switzerland) p. 1954. [3] R.
