Abstract

The general aim of this thesis is to do the radiofrequency (RF) design of a 2 MeV C-Band linac
for a RTM, the mechanical design and thermo mechanical calculations and to follow the
machining procedure. Afterwards, a test bench has to be designed so the RF cold
measurements may be carried out. In addition, the process of brazing of accelerating cavities
will be studied.
The novelty of this thesis arises from the fact that C-band linac was never used before in RTM.
Specific of linac operation in RTM is defined by necessity (i) to accelerate simultaneously in the
same linac low energy non relativistic beam from the electron gun and several different energy
relativistic beams from the orbits; (ii) to accelerate beams moving in opposite directions; (iii)
transverse dimensions are important to provide beam bypass at 1st orbit; (iv) to have
sufficiently large aperture to decrease beam losses; (v) to pay attention to parasitic modes,
especially to TM11 -like modes, which may cause transverse BBU (Beam Blow Up).
Due to this specific of RTM linac, its design for C-band cannot be just scaled from the known
designs for S-band. A full scale study, including beam dynamics and RF properties simulation
and optimization, engineering design, test and final measurements must be done within this
thesis.
