Plenary talk - normal and superconducting radio-frequency cavities for high energy particle accelerators

Advanced type-II superconductors are being developed for winding the high field dipole magnets that guide high energy elementary particles around their circular paths in colliding synchrotrons such as the Tevatron (at the Fermi national Accelerator Laboratory, FNAL, Chicago, IL) and the Large Hadron Collider (LHC, at Geneva, Switzerland). But an essential component of colliding synchrotrons, as well as linear accelerators (such as the proposed International Linear Collider, ILC), is the cluster of radio-frequency (RF) cavities that accelerator the particles to final energy.
