Division Large Research FacilitiesGFA

The Division of Large Research Facilities (GFA) is responsible for the construction, operation and development of the particle accelerators at PSI. Accelerator facilities form the backbone of the main research activities at PSI. The high intensity proton accelerator (HIPA) is used to generate muons for muon spin spectroscopy (LMU ), and neutrons by spallation from a target (SINQ ). The Swiss Light Source (SLS) is a state-of-the-art electron storage ring which generates high brightness photon beams for users of synchrotron radiation (PSD ).

A hard X-Ray Free Electron Laser, SwissFEL, was inaugurated at the end of 2016. It is based on a low emittance 5.8 GeV linear electron accelerator. The facility provides extremely short, very bright pulses of X-rays for time resolved experiments. Construction of a soft X-ray free electron laser (ATHOS), driven by the same electron linac, has also begun. These instruments are used by a large national and international multi-disciplinary research community.

GFA is also responsible for the operation of a compact proton cyclotron and attached beamlines (PROSCAN), dedicated to the treatment of cancer patients within the Centre for Proton Therapy (ZPT). A third rotating gantry, GANTRY 3, was recently added to this treatment facility. A major upgrade of the SLS is currently under design. This upgrade will result in an increase of the brightness of the source by two orders of magnitude.

Current Highlight

28 janvier 2021
Next generation transverse deflection structures capable of providing new opportunities for beam diagnostics.

Novel X-band transverse deflection structure with variable polarization

The growing request for sophisticated electron beam manipulation techniques for the optimization of Free Electron Lasers (FELs) or novel acceleration techniques requires enhanced beam control capabilities  and characterization. One of the most important challenge is the development of new diagnostic techniques able to characterize the longitudinal phase space of the beam, including spatial correlation terms, with a resolution in the range of a few tens of fs to sub-fs.
