PITTSBURGH—Charged particle accelerators have been a central tool of basic physics research for almost a hundred years, perhaps most famously as “atom smashers” for understanding the elementary ...

VARIOUS authors have discussed hybrid modes in circular iris-loaded waveguides, from the points of view of pulse shortening, or beam blow-up, in high-current electron linear accelerators 1–5, and of ...

A SLOW wave structure suitable for an electron linear accelerator or a high-power travelling-wave tube can be obtained by loading a metal wave-guide with a dielectric, either in the form of a coaxial ...
