Crystal x-ray accelerator

Abstract

An ultimate linac structure is realized by an appropriate crystal lattice (superlattice) that serves as a ``soft'' irised waveguide for x rays. High-energy (\ensuremath{\sim}40 keV) X rays are injected into the crystal at the Bragg angle to cause Bormann anomalous transmission, yielding slow-wave accelerating fields. Particles (e.g., muons) are channeled along the crystal axis.
