We study mechanisms of vortex nucleation in Nb3Sn Superconducting RF (SRF) cavities using a combination of experimental, theoretical, and computational methods.

In this paper, we present a detailed analysis of the effects of quadrupole components in radiofrequency (RF) photoinjectors, which could occur either in the RF cavity or in the gun solenoid, and their compensation using a skew quadrupole corrector.

Achieving a low mean transverse energy or temperature of electrons emitted from the photocathode-based electron sources is critical to the development of next-generation and compact X-ray Free Electron Lasers and Ultrafast Electron Diffraction, Spectroscopy and Microscopy experiments. 

CBB is entering an important moment — our renewal for a second five year period. This has come quickly, as it feels like CBB, which is now starting its fourth year, has only just begun.

Congratulations to Matthias Liepe and Jim Sethna on being awarded an APS Fellowship. 

Particle accelerators, and the technology that enables them, are helping to shape the future. Things as diverse as extending Moore's law to combating climate change are being driven by the research being done at universities around the world, and particularly at the NSF-funded Center for Bright Beams.

Professor Kim has been named the 2019 Scientist of the Year jointly by the Korean Scientists and Engineers Association (US) and the Korean Federation of Science and Technology Societies (Korea)

Two College of Arts & Sciences faculty members were awarded grants by the U.S. Department of Energy as part of its Office of Science Early Career Research Program. Jared Maxson, Ph.D. ’15 and Brad Ramshaw, both assistant professors of physics, will receive at least $750,000 over five years to support their scientific endeavors.

As CBB Ph.D student Ryan Porter advances his research towards triniobium-tin cavities at Cornell, he is being recognized for his work in the field.
