The Swiss Light Source (SLS) at the Paul Scherrer Institut is a third-generation synchrotron light source. In the design of SLS a high priority was given to the items quality (high brightness), flexibility (wide wavelength spectrum) and stability (very stable temperature conditions) for the primary electron beam and the secondary photon beams. With an energy of 2.4 GeV, it provides photon beams of high brightness for research in materials science, biology and chemistry.
Application Area
- Support to processing of the measurements
Installation and upgrading of instruments, samples holders special equipment for users.
- Support to users during experiments
Technical and scientific support of the users during the operation of the experiments

Typical use cases of the SLS are:
- biosciences (protein crystallography, cell biology)
- medical research (microbiology, disease mechanisms, high-resolution imaging and cancer radiation therapy)
- chemical and environmental sciences (toxicology, atmospheric research, clean combustion and cleaner industrial production technologies)
- agriculture (plant genomics, soil studies, animal and plant imaging)
- minerals exploration (rapid analysis of drill core samples, comprehensive characterization of ores for ease of mineral processing)
- advanced materials (nanostructured materials, intelligent polymers, ceramics, light metals and alloys, electronic and magnetic materials)
- engineering (imaging of industrial processes in real time, high-resolution imaging of cracks and defects in structures, the operation of catalysts in large chemical engineering processes)
- forensics (identification of suspects from extremely small and dilute samples)
- materials modification and fabrication
1. The SLS offers unique research opportunities to academic research teams as well as industrial research groups. Some special features of SLS are: - a very large spectrum of synchrotron light ranging from infrared light to hard X-rays - a mixture of straight sections (short, medium and long), allowing an optimal use of a variety of undulators - undulators with flexible polarization schemes, giving e.g. the possibility to rapidly change the polarization in the kHz range - top-up injection, producing a constant beam intensity, very high stability environment for experiments - individual control of all magnet power supplies, giving optimal flexibility for the optical properties of the storage ring. 2. SLS Beamlines Each beamline at SLS is optimised for a specific technique. 18 beamlines equipped with: - Powder and single crystal diffractometers; - Femto-laser; - different types of high resolution spectrometers; - sample preparation environment. Actually 17 beamlines are in the operational mode, Phoenix, NanoXAS and XTreme are in the pilot phase and PEARL is under construction. Depending on the type of radiaation source, there are two types of beamlines (insertion-device and bending-magnet).
