SwissFEL ARAMIS and ATHOS Beamlines

SwissFEL Experimental Stations
Experimental stations of SwissFEL beamlines ARAMIS and ATHOS

SwissFEL has two beamlines, the hard X-ray beamline ARAMIS as well as the soft X-ray beamline ATHOS.
 

ARAMIS hard X-ray beamline

(in operation)
 

  • hard X-ray FEL, λ=0.1-0.7 nm
  • linear polarization, variable gap, in-vacuum undulators
  • first users 2017
  • operation modes: SASE & self seeded

For the ARAMIS beamline, two experimental stations are active and one under construction, namely:

ARAMIS beamline
ARAMIS beamline

 

  1. experimental station Alvra
  2. experimental station Bernina
  3. experimental station Cristallina


The X-ray pulses are deflected by special high precision mirrors to the different experimental stations. Every 10 ms, an X-ray pulse is generated in the ARAMIS beam line

 

ATHOS soft X-ray beamlines

(under construction/commissioning)
 

  • soft X-ray FEL, λ=0.65-5.0 nm
  • variable polarization, Apple X undulators
  • first users 2021
  • operation modes: SASE

For the ATHOS beamline, one experimental station is active, namely:

Experimental Endstations

For the first run, the Alvra and Bernina endstations are available. Click on the header to reach their respective homepage.

Alvra Instrument

The Alvra end station of SwissFEL specializes in measuring the ultrafast dynamics of photochemical and photobiological systems using a variety of X-ray scattering and spectroscopic techniques. For the Alvra branch, the Alvra Prime chamber and Alvra Flex in-air instruments are available with the following parameters: SwissFEL Alvra experimental station

Bernina Instrument

The Bernina instrument provides two versatile modular platforms and instrumentation optimized for ultrafast condensed matter science. Standardized are a 6-circle surface diffractometer configuration as well as vacuum chamber allowing down to 5K sample temperature, tender-to hard X-ray diffraction, and high THz field sample excitation. The pump laser system provides high degree of specificity through a large range of excitation options, from ultraviolet to phase stable THz pulses, including short pulse options targeted towards studying phenomena down to 10-20 fs total time resolution.

Cristallina

Maloja Instrument
Maloja Instrument

The Maloja instrument targets atomic, molecular and non-linear physics as well as chemical sciences with a broad suite of experimental techniques ranging from electron- and ion-spectroscopy, absorption spectroscopy to single-particle diffractive imaging.

Furka Instrument
Furka

The Furka experimental endstation, located at the soft x-ray Athos beamline of the SwissFEL, is dedicated to the study of quantum materials using time-resolved Resonant Inelastic and Elastic X-ray Scattering (tr-RIXS and tr-REXS) as well as X-Ray Absorption (tr-XAS) spectroscopy. In particular, tr-RIXS opens new scientific opportunities thanks to its unique capability to probe energy and momentum-resolved dynamics of elementary excitations involving different degrees of freedom in solids.
