The call II/2025 is open for the µSR instruments GPD, FLAME, GPS, HAL-9500 and LEM.
- Note that the instrument DOLLY is not available for call II/2025. It will be open for the 1st call I/2026 (deadline Dec 1, 2025).
- If you are not sure about the most suitable instrument for your research, necessary sample mass and sample alignment or any other experimental issue please discuss with the instrument scientists before the submission of the proposal.
Next deadline for submission in DUO (call II/2025):
- June 2, 2025, 23:59 CEST.
Allocation period:
- For the instruments FLAME, GPD, GPS, HAL-9500 and LEM:

Note that GPD will be available again only for call II/2025 for the allocation period October - December 2025, because all accepted proposals of call II/2024 had to be moved to July - September 2025 due to a failure of the liquid helium system/muE1 decay solenoid in summer 2024.
General Guidelines
Proposals have to be submitted via the DUO web interface. Please note, that the main text/description of the proposal, including figures, has to be uploaded as a pdf file, with a maximum of 3 pages and a maximum size of 4 MB.
For details about the PSI User Office, see here.
For a description of the instruments see here.
In addition to the normal access mode (i.e. Proposals) beam time can possibly be obtained through Requests for Urgent Beam Time (see below).
1. Proposals
- Allocation periods: see above.
- Deadline for submission in DUO for call II/2025: June 2, 2025, 23:59 (Swiss time, CEST).
- Please note: this is a hard deadline - post deadline editing of proposals will be disabled.
2. Requests for Urgent Beam Time (Director's Discretion Time)
Reserved for feasibility tests or urgent measurements on new materials. A very limited amount of beam time is reserved for urgent beam time requests. For the request of urgent beam time (typically 1 or 2 days) an informal letter containing the relevant information about the project, the sample, the requested instrument and number of necessary days may be addressed electronically at any time of a running cycle to:
