  SARAF-phase 1 at SOREQ, with its single 6 half-wave resonators cryomodule, is the first high current, superconducting low-beta linac in operation and it is presently delivering cw proton beams in the mA range. A phase 2 is foreseen for this linac which will allow acceleration up to 40 MeV of 2 mA cw proton and deuteron beams. The project status, the operational experience and the future goals of SARAF should be described.

MO1A02 Status of the European XFEL – Constructing the 17.5 GeV Superconducting Linear Accelerator 105
  • W. Decking
    DESY, Hamburg, Germany
  The European XFEL is presently under construction in Hamburg, Germany. It consists of a 1.2 km long superconducting linac serving an about 3 km long electron beam transport system. Three undulator systems of up to 200 m length each produce hard and soft x-rays via the self-amplified spontaneous emission (SASE) process. We will present the status of the civil construction and the accelerator components. The production of the 100 superconducting accelerator modules is distributed between industries and a collaboration of accelerator laboratories. We describe the carefully orchestrated production sequence, quality assurance measures and risk mitigation mechanisms. The last module is scheduled to be installed in the accelerator in spring 2015 and commissioning with beam will start in summer of that year.

MO1A03 SRF Linac Technology Development at Fermilab 110
  • V.P. Yakovlev, C.M. Ginsburg
    Fermilab, Batavia, USA
  Superconducting linear accelerators are developing for different applications – for fundamental researches in High-Energy and High – Intensity Frontiers, nuclear physics, energetics, neutron spallation sources, synchrotron radiation sources, etc. The linac applications dictate the requirements for superconducting acceleration system, and, thus, for SRF technology. Fermilab is currently involved in two projects: ILC and Project X, both are based on SRF technology. For High-Intensity Frontier investigations, the Project X – a multi-experiment facility is developing based on 3 GeV, CW H linac in the frame of a wide collaboration of US National Laboratories. In a CW H linac several families of SC cavities are used: half-wave resonators (162.5 MHz); single-spoke cavities, SSR1 and SSR2 (325 MHz); elliptical 5-cell β=0.6 and β=0.9 cavities (650 MHz). Pulsed 3-8 GeV linac and ILC linac are based on 9-cell 1.3 GHz cavities. In the paper the basic requirements and the status of development of SC accelerating cavities, auxiliaries (couplers, tuners, etc.) and cryomodules are presented as well as technology challenges caused by their specifics.
