Call for Proposals

• 02 June - 31 August 2025 (I-25)
• 01 September - 23 December 2025 (II-25)

Please note:

• The instruments POLDI, NEUTRA and BOA will not be available in the cycles I- and II-25 because of dedicated upgrade programs
• The new small angle scattering facility SANS-LLB that is presently being installed in collaboration with our French partners from LLB is expected to take some friendly users soon. For more information please contact the instrument team.
• The Neutron Microscope is an experimental setup that can be used on the instruments POLDI, ICON and BOA (if those are available, see above). If you intend to use the microscope setup, please submit your proposal for the main instrument (e.g. POLDI) and choose the option "Neutron Microscope" during the proposal submission procedure. Please discuss the choice of the instrument well ahead with the person in charge for the microscope.
• Finally, beamtime on the instrument MORPHEUS can be allocated by contacting the instrument responsible directly.

In the past, PSI launched also a call for joint X-ray and neutron proposals (SLS/MS-Powder beamline and SINQ/HRPT) in the field of powder diffraction, which is presently suspended because of the SLS 2.0 upgrade and the following IMPACT program. More information can be obtained here.
