Methods and hurdles for a live shot to shot polarization diagnostic — •Moritz Mogilowski1,2 and Markus Illchen1,2 — 1Universität Hamburg, Hamburg, Germany — 2CFEL, Hamburg, Germany
With the recent advances of free electron lasers, pushing further into the attosecond time regime with ultra short pulses investigation of the chirality and and its time dependence on electronic movements is becoming feasible. The polarization of the FEL pulse is critical and its charactisation is not only important for analysing the data but also an important live metric for the machine operators. In this poster a robust and flexible approach to a shot based live polarization diagnostic based on almost intrusion free electron time of flight spectroscopy is shown. Common failures and their remedies are also discussed.
