For sure, CBB has felt COVID-19’s impact. The hardest hit are our experimenters, and because our research is highly interdependent we are all affected by the loss of their observations. Nevertheless, I am impressed by CBB drive during this time - we are making progress and our discussions are as lively as ever. Indeed, if there are future health crises, CBB discoveries may help find a cure.

The plasma wakefield accelerator may accelerate particles to high energy in a future linear collider with unprecedented acceleration gradients, exceeding the GeV/m range.

In the field of beam physics, two frontier topics have taken center stage due to their potential to enable new approaches to discovery in a wide swath of science.

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.
