LMU: Laboratory for Muon Spin Spectroscopy

Department of the PSI Division Research with Neutrons and Muons, NUM

The Laboratory for Muon Spin Spectroscopy (LMU) at the Paul Scherrer Institute is responsible for the scientific exploitation, operation and development of muon-spin spectroscopy instruments at the Swiss Muon Source (SµS). The team of about 20 senior scientists, postdoctoral researchers and PhD students is involved on diverse research projects ranging from modern topics in condensed matter physics and materials science to energy research and chemistry.

• Worldwide unique instruments:
  The Low-Energy Muon (LEM) beam and µSR Spectrometer for the study of thin films, layers and surfaces;
  the high-field instrument (HAL-9500) equipped with specially designed detectors to perform studies in fields up to 9.5 Tesla and at very low temperatures;
  and the combination of very-high pressures (up to 2.8 GPa) combined with sub-Kelvin temperatures (GPD).

Information for SµS users

Due to the Corona crisis and technical problems the restart of operation of the PSI high intensity proton accelerator (HIPA) has been delayed and is expected earliest for the 27th of July. The pandemic team of PSI approved in-house research at the SµS from this date on. According to today's situation, external/foreign users at the SµS will be allowed as of September 1st.

We have prepared a new experimental schedule that you can find here.

We have shifted the approved experiments of foreign users to a date as late as possible in the year and we assume that you will be able to conduct your experiments at PSI. However, for all experiments foreign travel restrictions and entry requirements into Switzerland and PSI need to be carefully considered. Up to date information about travel restrictions for Switzerland can be found here.

Some experiments (especially for Dolly) had to be scheduled before September 1st. For these experiments and for those experiments where travel restrictions do not allow traveling to PSI, the PSI team offers to conduct the experiments for the users. In such a case, the samples will have to be sent to the instrument scientist in time and an experimental plan can be submitted once per day. Please note that only one sample change per day will be possible in this operation mode. Please get in contact with the instrument scientists for the planning of your experiment and to inform us about the shipment of your samples. For experiments that can not be conducted in this way, it might be possible to shift the beamtime to the next year.
