US scientists build toolkit for improving particle accelerator’s performance

Scientists have developed a toolkit to investigate and improve the performance of superconducting radiofrequency (SRF) cavities used in particle accelerators. The toolkit helps monitor and control the inner surface characteristics of cavities, which affect their efficiency. Tests showed that smoother SRF cavities function more efficiently, and the toolkit can predict performance by quantifying surface smoothness. Researchers also found that grooves along grain boundaries can degrade accelerator performance, while oxygen-doped samples showed better topography. This research may help boost performance for future accelerators like the Electron-Ion Collider.
