SwissFEL ARAMIS Beamline

The SwissFEL Aramis hard X-ray (1.77 – 12.4 KeV) beamline consists of three beamlines delivering the FEL radiation into separate experimental hutches. The initial phase of operation will cover the first two experimental hutches. The Experimental station Alvra (ESA) is focussed on ultrafast photochemistry and photobiology, while the Experimental station Bernina (ESB) on ultra-fast dynamics of condensed matter physics. The beamlines include several different diagnostics elements to report for every pulse the X-ray spectrum, energy, and beam position. For pump-probe studies, a specialized timing diagnostic tool provides shot-to-shot information on the relative time-delay between the optical laser excitation pulse and the probe X-ray pulse with an accuracy of <10 fs.
