Design and Analysis of the Medium-β Elliptical Cavities for the European Spallation Source Accelerator
(2017)- Abstract
- This thesis is dedicated to the design and analysis of superconducting
elliptical cavities. Elliptical cavities play a central role in modern particle ac-
celerators due to their high efficiency. After an introduction to the European
Spallation Source project, the thesis goes through the design of the medium-β
cavity. The RF design of the inner cell and end cell are presented in sequence
in paper I . The design is completed by the chapter on the mechanical perfor-
mances of the cavity (paper II).
Papers III, IV and V are instead dedicated to the analysis of the cavity.
The necessary mathematical tools for the analysis are presented in paper III
which, after stating fundamental results on hollow cavities,... (More) - This thesis is dedicated to the design and analysis of superconducting

The necessary mathematical tools for the analysis are presented in paper III
which, after stating fundamental results on hollow cavities, presents a spec-
tral decomposition used in the following papers. In paper IV, a time-domain
model for the power dissipation induced by the excited higher-order-modes is
presented. Such modes are excited by the particle beam that passes through
the cavity and are detrimental to the performances of the accelerator. Paper
V presents a time-domain model of the cavity coupled to an externa circuit to
a coupler. The model is functional to the design of the cavity control system. (Less)
