Preliminary results on open accelerating structures
Abstract
Periodic structures consisting of rows of spherical conductors are considered. In a plasma linac, these spherical conductors would be formed from liquid droplets on whose surfaces a plasma would be formed. The field configurations have been investigated using copper spheres approximately 11 cm diameter and microwave radiation of approximately 30 cm wavelength. No suitable accelerating mode was found for relativistic particles using a single row of spheres, but with two parallel rows of spheres both accelerating and focusing modes were found. The accelerating modes is discussed over a grating surface, including a grating of parallel conducting rods. The coupling of these structures to incoming radiation are reexamined.
