MAX IV opens Calls for proposals twice per year for the User Science Programme. The calls are named according to their beamtime period, not when the call itself opens.
Fast Access operates with a rolling call intended for projects that require quick access to beamtime, for a short time.
How beamtime calls & cycles are approximately split:
Spring Cycle:
Call opens: September
Approx. Beamtime period:
March – August
Fall Cycle:
Call opens: February
Approx. Beamtime period:
September – February
Fast Access:
Rolling Call: All year

Published call results
In order to increase transparency towards our funders and user community, MAX IV management has decided to publish the Main Proposer’s last name and affiliation, and starting Spring24, the full title of the proposal, for all proposals accepted through the User Science Programme.
