investigated. Perturbation tests of normal conducting models of this cavity have been launched to verify these results.
The effect of the final focus quadrupole magnets on the deflection given to the bunch have also been calculated and
used to calculate luminosity loss due to wakefields.

Diamond will operate with up to three superconducting
cavities provided by ACCEL
Instruments. Each will be capable of delivering
300 kW of RF power to the beam to make
up for radiation losses, and each will provide an accelerating voltage of up to 2 MV. This paper will review the results
of the cavity vertical test and the window conditioning prior to assembly. We will also present measurements from
the cavity commissioning following installation in the Diamond Storage Ring.
Low- and Intermediate-beta, 352 MHz Superconducting Half-wave Resonators for High

A beta=0.17, 352 MHz superconducting
Half-Wave resonator was designed and constructed
at INFN-LNL in the framework of
the SPES and EURISOL projects. This cavity,
together with the beta=0.31 HWR of similar design that was previously built in the framework of the SPES project,
allows acceleration of high power hadron beams in the 5?100 MeV/u energy range, as required in the SPES primary
linac and in the first part of the EURISOL proton driver. Main features of this structure, compared to other ones
developed elsewhere with different geometries for similar applications, are compactness and mechanical stability.
Characteristics and test results will be presented.
