Areas of Research Interest

SCRF accelerating cavities are proposed for nearly every major new particle beam accelerator project in the world, including the International Large Collider (ILC) and Argonne’s Energy Recovery Linac (APS-ERL). While very different devices, each new accelerator pushes the current operating limits of SCRF cavities (e.g. acceleration gradients for ILC and loaded Q-factor for APS-ERL). The nature of the SCRF cavity surface (the first ~10 nms) facing the particle beam, is a crucial component of the cavity performance for both Q and gradient. Using Atomic Layer Deposition (ALD), it seems possible to control the surface composition of Nb SRF cavities, to control multipactoring, to improve Q, and to synthesize superconducting structures with significantly improved critical field (both magnetic and electrical) properties.
