SwissFEL

SwissFEL is one of only a handful of free-electrons laser facilities worldwide that is capable of producing the ultra-short, high intensity, hard x-ray pulses that are revolutionising x-ray science. The laser-like x-ray emission provides users with the possibility to probe the state of matter on atomic length and time scales opening the door to many experiments that will help to determine the relationship between electronic and atomic structure in novel quantum materials.

Swiss Light Source

The Swiss Light Source (SLS) at the Paul Scherrer Institut is a third-generation synchrotron light source. With an energy of 2.4 GeV, it provides photon beams of high brightness for research in materials science, biology and chemistry, hosting 16 beam lines in total.

SINQ: The Swiss Spallation Neutron Source

The Paul Scherrer Institute with SINQ is the national provider of large-scale infrastructure for neutron scattering, consisting of a powerful 1 MW spallation neutron source, state-of-the-art instruments for research using neutron spectroscopy, diffraction, small angle scattering, reflectometry and imaging, and of advanced sample environment. Neutron scattering is one of the most effective ways to obtain information on both, the structure and the dynamics of condensed matter paving the way for many discoveries in the field of quantum technology.

SµS: Swiss Muon Source

Research at the Laboratory for Muon Spin Spectroscopy (LMU) uses positive and (occasionally) negative muons (µ+, µ-) as local magnetic probes in matter. The experimental technique referred to as µSR (for Muon-Spin Rotation/Relaxation) is universally applicable since the muons available at meson factories such as HIPA, the PSI proton accelerator complex, can be implanted in any material. LMU operates 6 state-of-the-art µSR instruments capable of covering a large range of experimental parameters such as temperature, pressure or magnetic field. The low energy muon instrument is a worldwide unique facility that allows to perform depth dependent µSR investigations on a nanometer scale to study e.g. heterostructures, thin films, low dimensional systems, near surface effects or nanoparticles.

LMN clean room facilities

The Laboratory for Micro and Nanotechnology (LMN) specialises in the research of nano and microfabricated structures, essential for realising quantum technology devices. The facilities include a surface sciences lab, a clean room, specialized 'industry grade' electron beam lithography equipment and x-ray interference lithography based at the Swiss Light Source.

Cryogenic sample environment

The precise control of external parameters like magnetic field and temperature over a wide parameter space is a prerequisite for any experimental investigation. In particular, the control of temperature is of critical importance to study quantum phenomena as it defines the energy and time scales of decoherence. We have a long lasting record of expertise in providing a broad range of sample environment to the SINQ user program. In addition, we contribute with our competence in cryogenics to running and emerging projects at PSI.

Physical properties laboratory

The Physical Properties of Materials Group of the Laboratory for Multiscale Materials Experiments (NUM) prepares and characterizes advanced materials featuring novel structural, electric and magnetic properties. For these fundamental studies we use in-house equipment in combination with experiments at the PSI large scale facilities. The group operates and maintains the following equipment:

  • PPMS 9T, Quantum Design (2 Devices)
  • MPMS XL 7T, Quantum Design

IR beamline X01DC (@SLS)

The IR beamline X01DC is hosted at the Swiss Light Source, The beamline makes use of 100ps pulses of synchrotron radiation, emitted with a repetition rate of 500MHz. While IR spectroscopy is mainly used to investigate the chemical composition of samples, with common applications in astronomy, biology, chemistry, and forensic sciences, at X01DC it is used with low temperature and magnetic field sample environments to investigate low energy quantum states and low energy excitations in the condensed phase. We have three experimental endstations:
  • A high resolution transmission Fourier transform interferometer setup.
  • A transmission / reflection spectroscopy setup for the investigation of condensed matter
  • A synchronized infrared pump-probe spectroscopy setup for the investigation of dynamic solid-state properties.

Surface / Interface: Spectroscopy beamline (@SLS)

The Surface and Interface Spectroscopy (SIS) beamline hosted at that Swiss Light Source provides a state-of-the-art experimental set-up to study the electronic band structure of novel complex materials by spin- and angle-resolved photoelectron spectroscopies. The beamline has been designed for the energy range from 10 to 800 eV with high flux, high resolution, variable polarization, and low high-harmonic contamination.

ADRESS - X03MA: ADvanced RESonant Spectroscopies Beamline (@SLS)

The ADvanced RESonant Spectroscopies (ADRESS) beamline installed in the X03MA straight section of SLS is a high-performance soft-X-ray undulator beamline operating in the energy range from 300 eV to 1.6 keV. It hosts two endstations, for Angle-Resolved Photoelectron Emission (ARPES) and Resonant Inelastic X-ray Scattering (RIXS). The scientific activity at the beamline is focused on correlated systems (transition metals and rare earths) and nanostructures.

Quantum Design (QD) Physical Property Measurement System (PPMS)

The main probe is resistivity with temperature range from 400 K down to 1.8 K.  The magnetic field range is up to 9 Tesla.  The resistivity probe allows in-situ sample rotation with respect to the magnetic field, which can facilitate angle dependent magnetoresistance measurements, angle dependent Hall effect, and planar Hall effect.
 
There is also the ACMS option, which allows DC magnetization and AC susceptibility measurements. However it is not as sensitive as the SQUID magnetometer
