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 ... (More)

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. (Less)
