MAX IV opens Calls for proposals twice per year for the General User Access program. The calls are named according to their beamtime period (and year), not when the call itself opens. The two calls & beamtime cycles are split approximately like this:
Spring Cycle call for proposals
Call opens: September
Approx. Beamtime period: March – August
Fall Cycle call for proposals
Call opens: February
Approx. Beamtime period: September – February

The table below lists which beamlines are open to what access types (proposal types) for the current open call, or the next one if no call is currently open.
