The SwissFEL X-ray Free Electron Laser (XFEL) facility started construction at the Paul Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in 2018 on the Aramis hard X-ray branch. In the following sections we will summarize the various aspects of the project, including the design of the soft and hard X-ray branches of the accelerator, the results of SwissFEL performance simulations, details of the photon beamlines and experimental stations, and our first commissioning results.

The Materials Science beamline at the Swiss Light Source has been operational since 2001. In late 2010, the original wiggler source was replaced with a novel insertion device, which allows unprecedented access to high photon energies from an undulator installed in a medium-energy storage ring. In order to best exploit the increased brilliance of this new source, the entire front-end and optics had to be redesigned. In this work, the upgrade of the beamline is described in detail. The tone is didactic, from which it is hoped the reader can adapt the concepts and ideas to his or her needs.

The SwissFEL soft X-ray free-electron laser (FEL) beamline Athos will be ready for user operation in 2021. Its design includes a novel layout of alternating magnetic chicanes and short undulator segments. Together with the APPLE X architecture of undulators, the Athos branch can be operated in different modes producing FEL beams with unique characteristics ranging from attosecond pulse length to high-power modes. Further space has been reserved for upgrades including modulators and an external seeding laser for better timing control. All of these schemes rely on state-of-the-art technologies described in this overview. The optical transport line distributing the FEL beam to the experimental stations was designed with the whole range of beam parameters in mind. Currently two experimental stations, one for condensed matter and quantum materials research and a second one for atomic, molecular and optical physics, chemical sciences and ultrafast single-particle imaging, are being laid out such that they can profit from the unique soft X-ray pulses produced in the Athos branch in an optimal way.

The SwissFEL Injector Test Facility operated at the Paul Scherrer Institute between 2010 and 2014, serving as a pilot plant and test bed for the development and realization of SwissFEL, the x-ray Free-Electron Laser facility under construction at the same institute. The test facility consisted of a laser-driven rf electron gun followed by an S-band booster linac, a magnetic bunch compression chicane and a diagnostic section including a transverse deflecting rf cavity. It delivered electron bunches of up to 200 pC charge and up to 250 MeV beam energy at a repetition rate of 10 Hz. The measurements performed at the test facility not only demonstrated the beam parameters required to drive the first stage of an FEL facility, but also led to significant advances in instrumentation technologies, beam characterization methods and the generation, transport and compression of ultralow-emittance beams. We give a comprehensive overview of the commissioning experience of the principal subsystems and the beam physics measurements performed during the operation of the test facility, including the results of the test of an in-vacuum undulator prototype generating radiation in the vacuum ultraviolet and optical range.
About Me
Marco Calvi is an accelerator physicist working since 2009 at the Photon Science Division of the Paul Scherrer Institute (PSI). He received his PhD in 2004 at the University of Geneva in the Department of Quantum Material Physics under the supervision of Prof. R. Flükiger. Then, he started his career at CERN during the construction of the Large Hadron Collider (LHC) in the domain of high-field superconducting magnets. Later, he moved to EPFL for joining the ITER project and the cold cable tests of its superconducting Tokamak. At the beginning of the SwissFEL project, Dr. Calvi was hired by PSI to work on the undulator system of its first hard X-ray beamline, Aramis. Today, after more than 10 years, he is a senior scientist in the domain of accelerator-based light sources, both synchrotrons and FELs. His favorite research field is high-temperature superconducting undulators (HTSU). His institutional responsibilities include serving as the Athos Beamline Sub-Project leader for the Elliptically Polarised Undulators project, the Apple X Type High-Temperature Superconducting Undulator (HTSU) project leader, spokesperson for the Working Group on Photon Sources of the LEAPS initiative, and being responsible for superconducting magnets in light sources within the Swiss Accelerator Research and Technology (CHART) initiative.
