Multiphysics Analysis of Normal Conducting RF Cavities for High Intensity Proton Accelerators

M. Hassan[1], I. Gonin[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermi National Accelerator Laboratory, Batavia, IL, USA

Normal conducting cavities are typically used in the front end of proton accelerators to get the beam accelerated to velocities approximately a few tenths of the speed of light, where superconducting cavities can then be used to accelerate the beam to the speed of light. The warm part of ... Per saperne di più

Modeling of Multiconductor Microstrip Systems on Microwave Integrated Circuits

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics® to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate ... Per saperne di più
