SwissFEL ARAMIS and ATHOS Beamlines

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:

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, two experimental stations are active, namely:

1. experimental station Maloja
2. experimental station Furka

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 Instrument

The Cristallina endstation hosts experimental stations for protein crystallography (Cristallina-MX) and quantum condensed-matter science (Cristallina-Q). For the former, a fixed-target sample delivery platform is available, which can be operated in combination with a pump laser generating nanosecond excitation pulses in the mid-IR to UV wavelength range. The latter provides extreme conditions of temperature and magnetic field necessary to access the quantum regime, and includes an Ultralow-T Vectormagnet as well as a Pulsed Magnet setup, each installed on a heavy load diffractometer. The experimental stations are moved on airpads between preparation areas and the beam position, allowing for vibration-free sliding on the large granite floor.

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.

General information can be found at: SwissFEL Maloja Experimental Station.

Furka Instrument

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.
