Multiphysics Design of a Klystron Buncher
Publié en 2015
The Multiphysics design of a 130 GHz klystron Buncher cavity is described in this paper. In this high frequency range, dimensions are critical and expose the device to multiple physics effects, due to the power dissipations, affecting the electromagnetic performances. The proposed device is integrated with a carbon nanotube cold cathode in order to reduce thermal expansion and an opportune airflow controls the temperature. The multiphysics design is performed on COMSOL in order to ensure the desired behavior in operative conditions. Electromagnetic fields and scattering parameters have been computed when the Buncher is subjected to multiple physics factors. The appropriate geometries and materials and can be found.
