SwissFEL ARAMIS and ATHOS Beamlines

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

 

  1. experimental station Alvra
  2. experimental station Bernina
  3. experimental station Cristallina (under construction)


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:

 

 

  1. experimental station Maloja
  2. experimental station Furka

Experimental Endstations

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


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 will be available with the following parameters: SwissFEL Alvra experimental station

The Bernina instrument presently provides two interchangeable platforms, the X-ray Diffractometer (XRD) equipped with a two circle detector arm, and the General Purpose Station (GPS) with a multi-purpose horizontal 2-theta arm. Both platforms/endstations can be completed with a sample platform choice of a 6 DOF heavy load goniometer, a 2-circle surface diffractometer combination plus hexapod, and a kappa arm. An additional 6 DOF robot arm can be used for flexible detector positioning.

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.
