PSI photon, neutron and muon user facilities newsletter
In today's fast-moving society, standing still is effectively synonymous with regression. This is also true for dynamic fields of scientific investigation. If the Paul Scherrer Institute, as a research laboratory of high international standing, is to continue to provide state-of-the-art scientific infrastructures beyond the coming 10-15 years, it must lay the foundation today for an internationally competitive future. The new X-ray laser project, known as SwissFEL, will extend PSI's unique platform of interdisciplinary and international facilities to serve research teams from universities and from industry. The SwissFEL is an essential part of PSI's strategic focus, and will establish Switzerland's leading position in scientific research for years to come. It will attract top scientists from all over the world and will enhance PSI's acknowledged position as a world-class research institute. Furthermore, the new high-tech facility will provide an incentive for Swiss industry, through which existing highly-qualified jobs can be maintained and new ones created.

SwissFEL Project overviewThe SwissFEL project is progressing well. The baseline design of the 5.8 GeV linear accelerator and two undulator lines is nearly complete. This design is documented in the SwissFEL conceptual design report, presently under preparation. Among the special design features are: wavelength coverage from 1-70 Å, r.m.s. pulse length of less than 12 fs, 100 Hz pulse rate in both FEL lines and polarization control for soft X-rays. The technical R&D is moving ahead rapidly, with the first test facility (OBLA) in operation and the second one (250MeV Injector) under construction. The Scientific case report is completed and the presentation to the ETH board will be made at the end of 2009. It is foreseen that the project will be included in the
BFI Botschaftto be discussed in Swiss parliament in 2011. A construction period of 4 years is planned, beginning 2012, with the goal to start the commissioning in early 2016.
OBLA test facilityThe electron gun, which determines the quality of the electron beam, is the most sensitive component in a linear accelerator like SwissFEL. Since the electron beam quality determines the total length of a FEL, particular effort is put in the electron gun development (i.e. the focus is on the first few meters of the accelerator). In January 2009, the commissioning of the SwissFEL electron gun test stand started. Just six months after production of the first beam, the electron beam quality required for the low charge operation mode (10 pC) of the SwissFEL was reached. This makes us confident that the new electron source concepts used can surpass beyond the required parameters. Lasing could then be obtained with shorter undulators - a step forward - which could decrease the investment costs of SwissFEL.

The chairman of the editorial board, Bruce Patterson, would like to thank the many colleagues who contributed to this effort.

Facility newsSwissFEL Industry Collaborations:
SwissFEL is actively collaborating with industry- some contacts have resulted from the SwissFEL Industry Day, which took place on May 4th 2009, and others originate from earlier cooperations of PSI with industry.
Potential projects in different areas are in discussion: HF Accelerating systems, Undulators, High Performance Computing, Vizualisation and Image Processing.
However, PSI is still seeking industry partners in several areas; therefore a list of areas of possible cooperation for SwissFEL is planned to be published via the PSI web page. Contact details will be provided.
EC access programs at SLS/SINQ/SμS:
The amount of EC funding within the access programs NMI3/ELISA has significantly been cut by the EC. As a compensation PSI has decided to allocate own funds to support as many users as possible for the next months. Please note that this is not a permanent solution and we strongly hope that the EC will rise the available funding of the access programs in the next callperiod.
