Krasnov² ¹Moscow Engineering Physics Institute (State University), Moscow, Russia ²Identification Beam Systems LLC, Atlanta, USA Abstract This paper presents the results of a survey study that analyzed and compared several linear accelerator designs operating in the range of 5 to 20 MeV for use in advanced cargo inspection systems. These designs were based on klystron generated RF power input of 3.2 and 4.5 MW at 5712 MHz. Several different accelerating structures were considered including standing wave (SW) and travelling wave (TW) structures. In addition several hybrid structures, composed of a SW buncher section and TW accelerator section, were included in the study. Cells geometries and beam dynamics parameters, for these accelerating structures, were calculated using advanced numerical simulation methods. Accelerating structures and input couplers for SW and hybrid structures were designed. ª – corresponding author |

Zavadtsev³ ¹Moscow Engineering Physics Institute (State University), Moscow, Russia ²Skobeltsyn Institute of Nuclear Physics, Lomonosov Moscow State University, Moscow, Russia ³Scantech Sciences LLC, Atlanta, USA Abstract An investigation of input coupler asymmetry influence on electron beam's dynamics in energy recovery linacs (ERL) with superconducting cavities was carried out. There were considered several types of input power couplers – coaxial and waveguide, asymmetric and symmetric. Based on numerical modeling distribution of electromagnetic fields in accelerating cavity with input coupler was found, the transverse deflecting impulse was calculated. RTMTRACE software was adapted for beam's dynamics modeling. ª – corresponding author |
