Donald Hartill, a professor of physics emeritus in the College of Arts and Sciences and a driving force behind decades of experimental research in particle physics, died on April 16. He was 86.

Workshops at CHESS are an ideal way to learn more about the techniques of CHESS. Each workshop is geared to strengthen users' knowledge about CHESS, while engaging each participant's needs in order to further the capabilities of CHESS.

On behalf of the CHESS User Office, we extend our heartfelt congratulations to our users and staff for a remarkably successful 2025_1 run cycle. Your dedication and research continue to inspire us!

On April 8, members of the CLASSE and CHESS communities gathered at Cornell Cinema for a private screening of The Accelerator, a new documentary chronicling the life and legacy of physicist Robert R. Wilson. 

While the particle accelerator buried beneath Cornell’s soccer field typically hums along 24 hours a day, 7 days a week, the spring down period offers a rare and essential pause in operations. For two weeks, the synchrotron powers down—giving CHESS technical staff, scientists, and engineers a valuable window to dive into hands-on work that’s impossible when the machine is running.

Just as a snowflake’s intricate structure vanishes when it melts and transforms when it refreezes, the microstructure of metals can change during the 3D printing process, resulting in strengths or weaknesses in the printed product.

Cornell researchers have captured an unprecedented, real-time view of how a promising catalyst material transforms during operation, providing new insights that could lead to replacement of expensive precious metals in clean-energy technologies.

A new technique transforms symmetrical semiconductor particles, producing films with extraordinary light-bending properties.
