The Advanced Photon Source will hold a virtual town hall for users interested in the project to construct the Polarization Modulation Spectroscopy (POLAR) feature beamline at 4-ID. The town hall runs from 10 a.m. to noon CDT on Friday, November 12, 2021. 
The U.S. Department of Energy’s (DOE's) Argonne National Laboratory has named Laurent Chapon as associate laboratory director for Photon Sciences and director of the Advanced Photon Source, a DOE Office of Science User Facility at Argonne.
Michael Kelly is a group leader in the Argonne Physics Division, and he has extensive experience designing components for accelerators. So when the people behind the upgrade of the APS were looking for someone with just that kind of experience to help them build the state-of-the-art electron storage ring that will be at the heart of the new facility, they knew where to find him.
The Advanced Photon Source will hold a virtual town hall for users interested in the project to construct the High-Energy X-ray Microscope feature beamline at 20-ID in the Long Beamline Building. The town hall runs from 10 am to 12 noon CDT on Monday, October 25, 2021. 
In preparation for the APS Upgrade, modifications were needed to the radiation shielding in the particle accumulator ring. The team expertly completed the job ahead of the estimated time needed.
Using APS x-rays, scientists will study tiny specks of asteroid 162173 Ryugu, collected by a Japanese space mission. Learning more about how this asteroid formed will further our understanding of the solar system, including Earth’s formation.
Laura Greene has been appointed by President Biden to serve on the President's Council of Advisors on Science and Technology. Greene is the chief scientist at the National High Magnetic Field Laboratory located at Florida State University, the University of Florida, and Los Alamos National Laboratory; and a member of the Advanced Photon Source Scientific Advisory Committee.
To provide x-ray beams that are both very bright and very tightly focused, an Advanced Photon Source (APS) team had to create a new system of mirrors, lenses and equipment for the upgraded APS.
The Advanced Photon Source will hold a virtual town hall for users interested in the project to construct the Coherent Surface Scattering Imaging (CSSI) feature beamline at 9-ID. The town hall runs from 1:00 p.m. to 3:00 p.m. CDT on Wednesday, October 6, 2021.
The most visible sign that the APS Upgrade Project is proceeding is the Long Beamline Building, home to two of the stations where researchers will carry out cutting-edge science experiments using the brighter x-ray beams. Construction of this new building has progressed ahead of schedule since its groundbreaking ceremony on July 22, 2020, and is on track for completion in June 2022.
In some ways, it’s no surprise Jie Liu grew up to be an engineer. She’s following in the footsteps of her father, who made engineering his career. From a young age, she said, she was fascinated by the big machines her father worked on, and she would take bicycles apart and put them back together, learning how they worked. Now she works as a principal mechanical engineer on the upgrade of the Advanced Photon Source, a DOE Office of Science user facility at Argonne.
You are invited to participate in a workshop on “Data Handling at the APS Coherent High-Energy X-ray (CHEX) Sector.” This online workshop will be held via Microsoft Teams on Thursday and Friday, October 21 and 22, 2021.
The APS/IIT 2021 XAFS Virtual Summer School was successfully held Aug 1-4 2021 online. This was a joint effort of IIT and the Advanced Photon Source and beamline staff.  More than a dozen people from ANL and IIT served as synchronous instructors, including Steve Heald, Matt Newville, Shelly Kelly, and other beamline scientists from the APS, and Grant Bunker, Carlo Segre, and Jeff Terry from IIT Physics Department. 
The 1,000th magnet for the Advanced Photon Source Upgrade has arrived at Argonne.  The 1,000th magnet is an eight-pole fast corrector magnet, which is used to alter the trajectory of the electron beam as it circulates around the storage ring at nearly the speed of light.
A feature story on the Argonne home page notes that "For more than 25 years, the Advanced Photon Source’s intense X-rays have enabled important breakthroughs. With a massive upgrade in the works, scientists will be able to see things at scale never seen before." The article provides a comprehensive look at the APS past, present, and future, including the role APS users played in the fight against COVID-19.
The call is now open for FY2023 applications for both the Maria Goeppert Mayer and Walter Massey fellowships.
In an interview with the International Society for Optics and Photonics (SPIE), APS user Stuart Stock (Northwestern University) discusses how x-ray diffraction reveals details of mummified remains.
To hear Xianbo Shi tell it, there is no substitute for on-the-job training in the field of X-ray optics. There is no particular educational track, he says, that will teach you how to design the complex series of synchrotron beamline optics (mirrors, lenses, monochromators, etc.) that manipulate powerful X-ray beams for scientific purposes. If you want to learn, you have to put down the books and go work at an X-ray facility.
As part of the recent APS/CNM Users Meeting, the APS Upgrade project hosted a question-and-answer session to address user questions about the timing and scope of the upgrade, and the benefits of the new storage ring and beamlines. Chief Project Officer Jim Kerby was joined by Jonathan Lang, X-ray Science Division Director, and Susan White De Pace, manager of the APS user programs. A document of frequently asked questions, including those asked at the Q&A session, has been compiled.
From Fox 32 News Chicago: Happy Birthday to a local lab that has been helping solve the world's problems for decades! Argonne National Laboratory is turning 75. Technology at the Lemont lab helps scientists at Argonne National Laboratory see tiny things to make huge discoveries. "The smaller the thing that you look at, the bigger the facility, so the APS is huge. You can fit Wrigley Field in the center of our electronic storage ring," said Stephen Streiffer, the Deputy Laboratory Director for Science and Technology.
