 APS 25-ID-C,D Update

 

  

We are delighted to announce that 25-ID-C,D has started scientific commissioning. This follows completion of the shielding verification and technical commissioning phases last fall. Our transition to normal operations is expected sometime during the 2025-1 cycle, which will begin on January 27. We plan to accommodate a few general users during 2025-1, and the scheduling for these users will likely be towards the end of the run when our scientific commissioning tasks are completed.

Although the deadline for proposals and beamtime requests has passed, rapid access is available for experiment requests at 25-ID-C,D during the coming 2025-1 cycle. We will contact individuals to schedule experiments as we move closer to completing our preparations.

 

 APS 20-BM Update

 

 

We are thrilled to announce that beamline 20-BM passed shielding verification in mid-December. Now, in the midst of the winter break maintenance period, we continue to work on technical commissioning tasks, and we expect to start the Winter APS 2025-1 cycle in technical and scientific commissioning. The latter will be an exciting time, during which all beamline instrumentation will be tested, and XAFS spectra of standard samples will be measured across the entire available energy range of 3.9 to 35 keV to ensure the functionality of the beamline.

 

If you believe that your samples would be appropriate for this period, please contact us. And please keep in mind that all experiments, even during commissioning, will require a general user proposal. Beamline 20-BM participated in the APS Proposal Call for 2025-1 but will not allocate beamtime until the beamline has passed technical commissioning and scientific commissioning. We will contact individuals to schedule experiments as we move closer to the completion of beamline commissioning. Thank you for your patience as we move towards resuming normal operations.

 

 APS 9-BM Update

 

 

The APS winter break which began on December 18th forced us to reassess our previous expectation that 9-BM would start the commissioning process during the 2024-3 cycle. Instead, the schedule for the restart of operations at 9-BM is delayed until after the current maintenance period. We fully expect to receive first beam at 9-BM during the 2025-1 cycle, which begins on January 27. To aid you in your planning, the restart process and schedule is summarized below. Please note that all experiments, even during commissioning, will require a general user proposal.

Once shielding verification is completed - a critical and significant step in the process - we will start technical commissioning, during which all beamline instrumentation will be tested and standard samples will be measured to ensure the functionality of the beamline. We will then enter the science commissioning phase, during which we will measure XAFS spectra across the entire available energy range of 2.1 to 40 keV. If you believe that you have samples that would be appropriate for this period, please contact us.

9-BM did participate in the APS Proposal Call for 2025-1, but will not allocate beam time until the beamline has passed shielding verification, technical commissioning, and scientific commissioning. As we move closer to the completion of beamline commissioning, we will contact individuals to schedule experiments.

 

 To all of our beamline users and colleagues:

 

 

We are excited to bring all of our beamlines back online, and to continue our collaboration with you. We will keep you updated on our progress.
