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 |
