SwissFEL

The New Highlight in Switzerland's Research Infrastructures

Welcome to the Website of the SwissFEL, Switzerland's X-ray free-electron laser at the Paul Scherrer Institute.

The SwissFEL is based on a novel technology holding exceptional promises for diverse areas of scientific research. Serving our society's modern trends "smaller, faster, more complex", SwissFEL will provide unprecedented insights into structures as small as an atom and into phenomena as fast as the vibrations of molecular bonds. It will also reveal the secrets behind the inner complexity of technologically relevant materials and biochemical structure and interaction.

Gas Attenuators

A compact gas attenuator for the SwissFEL ATHOS beamline realized using additive manufacturing

Gas attenuators are important devices providing accurate variation of photon intensity for soft X-ray beamlines. In the SwissFEL ATHOS beamline front-end the space is very limited and an innovative approach has been taken to provide attenuation of three orders of magnitude up to an energy of 1200 eV. Additive manufacturing of a differential pumping system vacuum manifold allowed a triple pumping stage to be realized in a space of less than half a meter. Measurements have shown that the response of the device is as expected from theoretical calculations.
