November eNewsletter Highlights

CHESS eNewsletter - November 2023 | Issue No. 113

From the Director

Dear CHESS community,

I am delighted to bring you updates on some exciting developments at CHESS.

First and foremost, yesterday, we were able to host an open house at the new Wilson West expansion project. Wilson West has received its temporary certificate of occupancy (TCO), a significant milestone in the High Magnetic Field Facility construction project. The TCO signifies a transition from building construction to the installation of highly specialized experimental equipment. We anticipate completing the “punch list” and receiving the certificate of occupancy on December 15^th. That will formally complete the building construction project.

Despite remarkable site constraints and challenges, the planning and construction crews - within and beyond CHESS - finished this project on time and on budget. I would like to personally and publicly recognize our construction Project Manager Alex Chevellard and the Facilities and Campus Services (FCS) team at Cornell for their expertise and dedication to this project. Well done everyone, and congratulations!

The momentum doesn't stop there— CHESS researchers have returned and are actively collecting data over the past month. Their passion for advancing scientific discovery always amazes me, and I look forward to the groundbreaking results that will emerge from their efforts.

I also want to draw your attention to two science highlights. The first, available here, delves into the validation of a residual stress model through cold hole expansion in aerospace aluminum alloy. The second, accessible here, explores intragranular micromechanical fields at triple junctions. These findings showcase the depth and diversity of research conducted at CHESS, both at our MSN-C and CHEXS partner beamlines.

The collaborative spirit at CHESS is what propels us forward, and we are grateful for the support and enthusiasm of our community.

Thank you for being a part of the CHESS family, and here's to the exciting discoveries that lie ahead!

Warmest regards,

Joel Brock, Director, CHESS (email Joel)

CHESS celebrates construction milestone with Wilson West open house

On Wednesday, November 15, CHESS had an open house for members of the Cornell community in the new Wilson West expansion project. The project recently received its temporary certificate of occupancy, which marks a milestone in the construction project. Explore a 3D walkthrough of the site at the link above, or read more and see photos at the link below.

Residual Stress Model Validation of Cold Hole Expansion in an Aerospace Aluminum Alloy

Recent measurements at CHESS produced data to validate a cold hole expansion (CHE) process simulation model as part of the United States Air Force (USAF) Enhanced Life Management by Engineered Residual Stress (ELMERS) program. The results quantify through-thickness residual stresses that will enable the USAF, and ultimately the taxpayer, to save money through more effective use of aerospace components.

Intragranular micromechanical fields at triple junctions

New research provides a 3D investigation using multiple synchrotron x-ray techniques to enable targeted zoom-ins onto six individual grains and spatial linking across length scales, characterizing the intragranular micromechanical fields along all triple junctions within select grains.

Estudiante de verano de CHESS en las noticias!

2023 PREM summer student Sebastián Muñoz Torres was recently featured in Puerto Rico's major newspaper, El Nuevo Día. Sebastián talks about his research into hydrogen technology in the daily paper. You can read more here, or check out Sebastian's Q&A with CHESS staff, or read about other students from this past summer.

CHESS is always looking for talented individuals to join our team! Please check out the latest job offerings available at the lab.
