URSA-PQ@FLASH: A mobile, highly flexible endstation for pump-probe electron spectroscopy at the FLASH free electron laser — •Jan Metje1, Dennis Mayer1, Fabiano Lever1, Mario Niebuhr1, Matthew Robinson1, Axel Heuer1, Richard Squibb2, Raimund Feifel2, Stefan Düsterer3, and Markus Gühr11University of Potsdam, Potsdam, Germany — 2University of Gothenburg, Gothenburg, Sweden — 3DESY, Hamburg, Germany

We designed and built a mobile, highly flexible endstation designated for users at the free electron laser FLASH called URSA-PQ (Ultraschnelle Röntgenspektroskopie zur Abfrage der Photoenergiekonversion in Quantensystemen). The main instrument consists of a vacuum chamber with molecular capillary oven, a magnetic bottle time-of-flight electron spectrometer, and various tools to perform pump-probe experiments with optical laser pulses and x-ray pulses. The main chamber body adheres to CAMP-standards and thus many different compatible instruments may be incorporated.

We present the design of the vacuum apparatus and its mobile frame together with the control system of the experiment. The performance of the instrument was evaluated from commissioning at the beamline FL24. We present static as well as time resolved data to show various characteristics of the instrument.
