Monday, April 17, 2023.  A date that has been circled on all of our calendars for months. It’s the day when user operations pause at the Advanced Photon Source (APS) to begin the year-long shutdown. The result will be a fully upgraded, state-of-the art APS.  

Rather than tell you again how excited we are to embark on this phase of the project, and how hard the entire team has worked to get us to this point, I’ll let the above video speak for me this month. In it you will meet just a few of the people who have spent the past years – and now will spend the next year – helping to make the upgraded APS a reality. I’m proud of our whole team, and of how each of the speakers in this video, on their own, acknowledges the contributions of their colleagues. The APS Upgrade team, the Photon Sciences directorate and Argonne operations are all pulling together to complete this project safely, restart the facility, and resume the scientific mission of the facility enabling discoveries for decades to come. 

These monthly communications will continue throughout the APS shutdown, and we’re excited to share our progress. For all the latest information, please visit the APS Upgrade web page.

Thank you,
Jim Kerby
Director, APS Upgrade Project
