The ALS-U project plan has now been updated, and we have revised our proposal calls leading up to the dark time. Dark time remains on track to start no earlier than October 2027 (~22 months). With substantial user beamtime anticipated in 2027, we’ve added a new proposal call due September 2, 2026. Learn more about the details and contact alsproposals@lbl.gov with questions. Read more »
No Proposal Call This March for August–December 2026
Because the ALS will not offer user beamtime in the second half of 2026, we are not issuing a call for new General User proposals or beamtime requests this March. Please note that RAPIDD access proposals may be submitted at any time. We also anticipate offering a few months of user beamtime in the first half of 2027. Read more »
Changes to Proposals for January–July 2026
The ALS-U project is evaluating a potential schedule shift, including a shutdown for dark time starting summer 2026. Since an earlier dark time is possible, our goal is to ensure active proposals receive needed beamtime and make beamtime requests accessible when possible. Learn more about the September proposal cycle changes. For any questions, contact alsproposals@lbl.gov. Read more »
