The Belle II experiment at the SuperKEKB accelerator measures particle interactions with extreme precision. Collisions of electron and positron beams create the high-energy environment needed to produce subatomic particles that do not otherwise exist in nature.

Belle II Detector Produces World’s Most Precise Measurements of Subatomic Particle Lifetimes

Particle lifetime measurements with early data from the Belle II experiment at the SuperKEKB accelerator demonstrate the experiment’s high precision.

Researchers have long thought pure niobium superconducting radiofrequency cavities were best for particle accelerators. Researchers are now using a toolkit to learn how to add impurities to the cavities to make them smoother—and more efficient.

Smoother Surfaces Make for Better Particle Accelerators

An enhanced topographic analysis toolkit for forecasting and improving particle accelerator performance is helping scientists build better accelerators.
