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 »
Processing Time for On-Site Users
Please remember that all on-site users must register well in advance of their scheduled beamtime. US citizens are required to complete registration at least 21 days before their experiment. Non-US citizens must register at least 60 days in advance due to updated DOE screening requirements. Please plan ahead to ensure timely processing and avoid delays to your access.
Call for 2024 and 2025 Publications
All publications resulting from work done in whole or in part at the ALS must be recorded by the User Office for the Department of Energy (DOE). To maintain accurate records and assess the productivity and scientific achievements of our beamlines, please report your ALS publications, especially those published in 2024 and 2025. 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 »
