TUXMH01	The European XFEL - Status and Commissioning	linac, electron, undulator, operation	11
	H. Weise DESY, Hamburg, Germany
	Funding: The European XFEL is funded by the respective funding agencies of the contributing countries. The European X-ray Free Electron Laser* in Hamburg, Germany, is being constructed by an international consortium. The facility is being built to offer photon beam of highest brilliance at wavelengths down to below 1 Angstrom. The accelerator complex with all its sections, the injector, the 17.5 GeV superconducting linac, bunch compressors, beam distribution systems etc. was built under the leadership of DESY. Seventeen European research institutes contributed to the accelerator complex and to the comprehensive infrastructure. DESY coordinates the European XFEL Accelerator Consortium but also contributes with many accelerator components, and the technical equipment of buildings, with its associated general infrastructure. With the finishing of the accelerator installation in autumn 2016, the first cool-down of the superconducting linac was started. Commissioning is next with the goal to demonstrate first lasing in spring 2017. Users are expected to use the first photon beams in 2017. A project overview and the status will be given illustrating the success of the collaborative work. * http://xfel.eu

	We present the results of the commissioning of the pulsed linear electron accelerator with beam energy of 10 MeV, developed with the participation of scientists and engineers of the SINP MSU, LEA MSU Ltd. and JSC "RPE "Toriy". The source of RF power for accelerator is a multibeam klystron KIU-147A operating at 2856 MHz with pulse output power 6 MW and an average power of 25 kW. As a result of commissioning we received at the output of accelerator scanning system an electron beam with an energy of 10 MeV and an average power of more than 15 kW. Capture ratio and electronic efficiency of 1.24 m long accelerating structure are greater than 65%.

	A.A. Zavadtsev RAS/INR, Moscow, Russia
	Funding: European XFEL GmbH, Ministry of Education and Science of Russia In frames of Russian in-kind contribution to Europe-an XFEL, INR in cooperation with DESY is responsible for Transverse Deflecting Systems (TDS) for special beam diagnostic in the XFEL linac. Three TDS have been developed: TDS INJ in the Injector, TDS BC1 in the Accelerator tunnel after Bunch Compressor 1 and TDS BC1 after Bunch Compressor 2. Each system in-cludes S-band disk-loaded deflecting structure (DLS), waveguide system, klystron, pulse transformer, modu-lator and control system. TDS INJ has been built, as-sembled in the Injector building and tested. It is used to monitor the bunch length, longitudinal phase space and slice emittance now. Exceptionally small, exceed-ing expectations, slice emittance of electron bunch was measured using TDS INJ during the XFEL Injector commissioning. Three structures for TDS BC1 and TDS BC2 as well as the waveguide systems have been built, tested and TDS BC2 part installed in the XFEL tunnel. On behalf of the joint XFEL TDS team

WEPSB006	On Modeling and Optimization of Intense Quasiperiodic Beam Dynamics	controls, electron, bunching, simulation	363
	I.D. Rubtsova St. Petersburg State University, St. Petersburg, Russia
	The paper is devoted to quasiperiodic beam dynamics investigation. Particle density is modeled by trigonometric polynomial. Space charge field is represented in the similar form. This approach is applied to beam dynamics investigation in klystron-type buncher. Numerical algorithm of polynomial coefficients calculation from the positions and impulses of model particles is formalized. As a result Coulomb field intensity is expressed in the form of integral over the set of particle phase states. Integro-differential beam evolution model is presented. Analytical expression of the variation of beam dynamics quality criterion is obtained. It makes possible directed methods using for beam dynamics optimization.

These modifications can provide the beam energy of 8-10 MeV and beam power up to 10^-12 kW. Facilities with the accelerating structure have been used for electron beam sterilization of medical disposables and food processing over ten years.
