Weixing Cheng

For the past five years, I have served as the diagnostics CAM and technical lead on the APS-U project, overseeing the design, construction, integration, and testing of various diagnostic systems. In June 2024, I became the ASD-DIA group leader. With over 20 years of experience in accelerator beam instrumentation and diagnostics, I have worked at some of the world’s leading high-energy particle accelerator laboratories, including KEK, SLAC, BNL, and ANL.

Before joining Argonne National Laboratory (ANL) in 2019, I spent more than a decade at Brookhaven National Laboratory, where I played a major role in the design, construction, and commissioning of diagnostic systems for the NSLS-II machine. My contributions included the transverse bunch-by-bunch feedback system, the visible synchrotron diagnostic beamline, and various other systems such as button BPM, fill pattern monitor, current monitor, tune measurement, photon BPM, and the X-ray pinhole beamline.

Earlier in my career, I worked at the KEK Photon Factory in Japan (2004–2007), where I developed a bunch-by-bunch feedback system. I also contributed to the development of synchrotron light monitor systems and transverse feedback activities at SLAC National Accelerator Laboratory (2007–2008) for the PEP-II and SPEAR3 accelerators.

I hold a Bachelor of Science degree from the University of Science and Technology of China (USTC, 1998) and a Doctor of Engineering degree from the Shanghai Institute of Applied Physics, Chinese Academy of Sciences (CAS, 2003).
