Recent Results from the Steady-State Microbunching Proof-of-Principle Experiment at the Metrology Light Source — •Arnold Kruschinski¹, Xiujie Deng², Jörg Feikes¹, Ji Li¹, Arne Hoehl³, Roman Klein³, and Markus Ries¹ — ¹Helmholtz-Zentrum Berlin, Berlin, Germany — ²Tsinghua University, Beijing, China — ³Physikalisch-Technische Bundesanstalt, Berlin, Germany

Steady-state microbunching (SSMB) has been proposed by Alex Chao and Daniel Ratner in 2010 to enable the generation of high-power coherent synchrotron radiation at an electron storage ring for wavelengths up to the extreme ultraviolet. The viability of the concept has been shown in a proof-of-principle (PoP) experiment at the Metrology Light Source (MLS) in Berlin. An enhanced detection scheme allows systematic studies of the conditions needed for the creation of microbunches within the continuing PoP experiment. It was found that the generation of coherent radiation from microbunches is favored in specific nonlinear longitudinal phase space structures, known as alpha buckets, which arise when the momentum compaction function becomes dominated by higher order terms. We present recent improvements to the experimental setup as well as newest results and their interpretation.
