Upcoming proposal deadlines:
Under the pre-proposal call, scientists can benefit from the support of the ReMade@ARI’s Smart Science Cluster team to develop their preliminary research idea(s) into a full ReMade-TNA proposal. Under the new Rolling Call, proposals can be submitted at any time during the period September 2025 – May 2026, giving scientists more flexibility and time to carefully prepare, develop, and refine their research ideas. The RIANA – TNA Access is Now Open. We accept user proposals based on a “continuous call” concept. Applications for Pre-proposals are not mandatory but are highly encouraged. The SME Call for Proposals is Now Open. The application is open throughout the project and implemented as a rolling call. The Call for Proposals for the 2026-II cycle for beamlines and microscopes is now open. The Call for Proposals for the 2026-II cycle will cover experiments scheduled from end of June to December 2026, except for the MX Beamlines, which will cover the entire year. For those users applying to MSPD, CLAESS and NOTOS: if your proposal goes to the waiting list, it can be moved to another beamline in case enough beamtime is available. Please, indicate your preferred beamline and the second option in the text of the proposal. Applications for researcher’s access to beamlines and electron microscopes will be submitted the user office portal. Twice a year, the CLS opens a Call for Proposals during which time proposals are accepted for peer-reviewed access to beamtime in the upcoming cycle. Each cycle is typically 6 months long. Successful proposals become active projects at the CLS and remain active for 2 years. During an open Call for Proposals, beamtime requests (BTRs) for active projects can also be submitted for consideration in the upcoming cycle. Round – 2026-II Beamtime period – July 2026 – January 2027 Deadline – 01.03.2026 (CET 11.59 pm) The next submission for proposals for AP40 is open. The call for proposals for AP40 (October 2026 – March 2027) is open and proposals must be submitted by Wednesday 25th March 2026 at 17:00hrs UTC/GMT. For submissions of proposals please see here: Apply for beamtime.
