This current PETRA III extension project comprises two new experimental halls on either side of the large new PETRA III hall (North and East) making use of the long straight sections and the adjacent arcs. The northern straight section already accommodates one of the long damping wiggler arrays producing an extremely hard and powerful X-ray beam which will be used for experiments. The long straight in the east will be used for additional insertion devices.
In total, 10 new beamlines will be built within the scope of the extension project. The reconstruction started in February 2014. Since February 2015, the technical hall infrastructure is being installed. The commissioning of the first two beamlines for X-ray absorption spectroscopy P64/P65 started in September 2015. They are avialbale for regular user operation since 2016.
Additional information on beamlines etc. is available on the PETRA III Extension project website.
