Abstract

The ESS elliptical superconducting Linac consists of
two types of 704.42 MHz cavities, medium and high beta,
to accelerate the beam from 216 MeV (spoke cavity
Linac) up to the final energy at 2 GeV. The last Linac
optimization, called Optimus+, has been carried out
taking into account the limitations of SRF cavity
performance (field emission). The medium and high-beta
parts of the Linac are composed of 36 and 84 elliptical
cavities, with geometrical beta values of 0.67 and 0.86
respectively. We describe here the procedures and
numerical analysis leading from half-cells to a complete
medium cavity assembly, which take into account not
only the frequency of the fundamental accelerating mode
but also the higher order modes near the machine line.
The half-cell selection process to form dumb bells will be
described, as well as the reshaping and trimming
procedure.
