Call for Proposals

• 25 May - 30 September 2026 (I-26)
• 01 October - 23 December 2026 (II-26)

Please note:

• As a new feature we will accept long term proposals for main proposers with Swiss affiliation (except PSI) for a duration of two cycles
• If you intend to submit proposals for experiments requiring gas infrastructure on the thermal neutron radiography station NEUTRA or for all experiments on the new small angle scattering facility SANS-LLB, it is expected to contact the respective instrument team first.
• The Neutron Microscope is an experimental setup that can be used on the instruments NEUTRA and ICON. If you intend to use the microscope setup, please submit your proposal for the main instrument (e.g. ICON) 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.
• The instruments POLDI and BOA will not be available in cycle II-26
• 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.
