Bio/Research
Superconducting radio frequency (RF) cavities are feet-long structures, providing extremely high electric field gradients (tens of MV/m) for the acceleration of particle beams. The electric field inside these cavities oscillates at GHz frequencies, with exceptional high quality factors of 1E10 to 1E11. By using superconducting materials operated at temperatures between 1.5K and 4K for the walls of the cavities, we can achieve such high efficiency. The evolution in the performance of superconducting cavities has revolutionized the performance and scientific reach of particle accelerators for a variety of science applications, including high-energy physics, nuclear physics, synchrotron radiation based research, and high power lasers. Future particle accelerators like the International Linear Collider, the LCLS-II x-ray FEL at SLAC, a muon accelerator, and the Energy Recovery Linac Light Source planned here at Cornell University all rely on the performance we hope to achieve in next generations of superconducting cavities.
