We demonstrate that a small discontinuity (such as an enlargement or a hole) on a smooth waveguide can result in the appearance of trapped modes localized in the vicinity of the discontinuity. The frequencies of these modes lie slightly below the cut

The Fortran 90 RIAPMTQ/IMPACT code package is a pair of linked beam-dynamics simulation codes that have been developed for end-to-end computer simulations of multiple-charge-state heavy-ion linacs for future exotic-beam facilities. These codes have m

The radio-frequency quadrupole (RFQ) accelerator is the best structure immediately after an ion source for accelerating light-ion beams with considerable currents. On the other hand, the higher-energy part of the RFQ is known to be not a very efficie

The Spallation Neutron Source (SNS) project includes a future upgrade option to 4 MW of beam power. The upgrade scenario stipulates adding a second front end and drift-tube linac, and then merging two 402.5-MHz beams from the parallel legs by interla

A new current structure for the fast traveling-wave 2.5 MeV beam chopper for the Spallation Neutron Source (SNS) project has been proposed. It is based on the meander-folded straight or notched stripline with separators. Detailed electromagnetic mode

A ceramic chamber inside kicker magnets can provide the relevant field risetime. On the other hand, some metallic coating inside has to prevent static charge buildup and shield the beam from ceramic and ferrite at high frequencies to avoid possible r

The beam coupling impedances of small obstacles protruding inside the vacuum chamber of an accelerator are calculated analytically at frequencies for which the wavelength is large compared to a typical size of the obstacle. Simple formulas for a few
