TUXRA01 Commissioning of PETRA III 1280

PETRA III is a new hard x-ray synchrotron radiation source at DESY in Hamburg operating at 6 GeV with an extremely low horizontal emittance of 1 nmrad. The new light source is the result of a conversion of the former storage ring PETRA II. The conversion was carried out from middle of 2007 till March 2009. One eighth of the 2304 m long storage ring was completely rebuild and houses now 14 undulator beam lines as well as the optical and experimental hutches. The remaining seven eighths have been modernized and refurbished and in addition twenty 4 m long damping wigglers have been installed. These are required to achieve the small design emittance. Commissioning of the new light source started at the end of March 2009. In this paper we present the results that have been achieved during commissioning and the experience gained during the first user runs.

TUXRA02 Status Report on Japanese XFEL Construction Project at SPring-8 1285

SASE based X-ray free-electron laser is now under construction at the SPring-8 site. This project is aiming at realization of SASE FEL of 1 angstrom initially and approaches to seeded XFEL in the second stage. For this future extension, a very unique system was adopted, composed of a low emittance SHB-based injector with CeB6 cathode thermionic gun, normal conducting high gradient C-band acceleration system and high performance in-vacuum undulators. This presentation will provide a comprehensive project review and recent project progress.
