Abstract: An accelerator for a linear beam of charged particles has a first accelerating section upstream which modulates and accelerates the dc beam. This section is a traveling-wave circuit through which the entire rf power flows from the driving source. Output power from the other end of the traveling-wave section flows through a transmission line to a standing wave accelerating section downstream of the input section. An attenuator and a phase shifter between the two sections allow adjustment in the energy added to the particles in the downstream standing-wave section without disturbing the synchronism of the beam with the upstream accelerating section. As a result a high efficiency of acceleration and narrow energy spread of the final accelerated beam are achieved over a wide range of particle energies.

Abstract: In the field of side-cavity coupled accelerators the accelerating cavity to which the accelerating power input is connected has preferably a smaller diameter than the other accelerating cavities. A side cavity is connected by a separate passage to the accelerating cavities of different diameter it couples together, whereby the areas of the coupling irises formed where said passages enter said accelerating cavities can be independently controlled by selecting the length of the respective passage. This separate passage arrangement is particularly described in an accelerator which comprises a plurality of interlaced substructures, with each substructure having a plurality of accelerating cavities disposed along the particle beam path and having side cavities disposed away from the beam path for electromagnetically coupling the accelerating cavities. A standing radio-frequency electromagnetic wave is fed to an accelerating cavity in each substructure so there are plural driven cavities in a single accelerator. Thus, the separate coupling passage arrangement between the side cavity and the accelerating cavities it couples is particularly valuable in said multiple substructure arrangement.

Abstract: Klystron cavities having linearly movable tuning elements are tuned simultaneously by a single master control which tilts a tuner drive platform. The motion is transmitted to individual cavity tuners by drive elements on the platform at selectable distances from its tilting axis so that the tuning rate of each cavity may be selected for proper tracking with the others. Individual position adjustments of each tuner allow exact setting at a selected reference frequency. The combination of the two sets of independent adjustments permits the resonant frequencies and tuning rates to be independently set at a given reference frequency, or alternately the resonant frequencies may be aligned at two different reference frequencies. Thus the cavity frequencies are made to track during continuous tuning over a wide range.

Abstract: In a velocity modulation tube comprising a floating prebuncher and at least one final prebuncher, frequencies of respective fundamental modes of resonance of the input cavity, the floating prebuncher, and the final buncher are adjusted to the lowest frequency of the passband of the tube, adjacent to the highest frequency of the passband, and higher than the highest frequency, respectively. Furthermore, the Q-value of the floating prebuncher is made equal to or lower than that of the input cavity. Naturally, the output cavity has its fundamental mode of resonance approximately at the center of the passband.
